The Wi-Fi standard 6 was officially launched today and the Wi-Fi Alliance now awards Wi-Fi 6 certifications to manufacturers with eligible hardware. We will start seeing devices and equipment with Wi-Fi support 6 coming to the market in the near future.
The Wi-Fi 6 has several features that make it advantageous compared to 802.11ac (also called Wi-Fi 5). First of all, for those of you who may not remember where this nickname "Wi-Fi 6" comes from: The Wi-Fi Alliance have defined certain specific Wi-Fi levels (4, 5 and 6) corresponding to certain levels of technology. Wi-Fi 4 corresponds to 802.11n, Wi-Fi 5 to 802.11ac and Wi-Fi 6 to 802.11ax.
802.11ax is designed to integrate more Wi-Fi signals into the same congested space, especially in your home / business / local NFL stadium. The standard shines in dense deployments, with throughput up to 4x greater than 802.11ac, even though nominal nominal speeds have only improved by 37% in the best of times. The 802.11ax standard uses OFDMA (Orthogonal Frequency Division Multiple Access) to subdivide the spectrum for simultaneous assignment to many users (this feature was missing in the 802.11ac standard). It can simultaneously use multi-user MIMO and multi-user OFDMA, and has features for more efficient spectrum sharing and reuse between devices.
According to the Wi-Fi Alliance, all of these enhancements are needed to support the heavy deployments of today's homes. In the early days of Wi-Fi, the only enabled device could be a laptop or two. Today, a household can have 3 to 5 computers, 3 to 5 phones, a smart TV and a smart speaker. However, device manufacturers must plan for a future in which a router might be juggling connections with 3 to 5 computers, 3 to 5 phones, 2 to 4 smart TVs, 4 to 6 smart speakers, and 20 to 30 smartphones. different IoT. appliances and devices deployed throughout the house. Cumulate as many products and start encountering local interference from your own network, not to mention what your neighbor might be doing.
The other major feature introduced with Wi-Fi 6 is the WPA3. Unfortunately, it has already been confirmed that WPA3 suffered from some of the same security vulnerabilities as WPA2. Earlier this year, security researchers published results demonstrating these vulnerabilities and called the development approach used to certify WPA3 fundamentally flawed. "In light of the attacks presented, we believe that WPA3 does not meet the standards of a modern security protocol," wrote the authors. "In addition, we believe that our attacks could have been avoided if the Wi-Fi Alliance had created WPA3 certification more openly."
There are many ways to force WPA3 into a degraded mode that exposes network information insecurely, and the standard as a whole does not seem to be as powerful as WPA2 or WPA was perceived in their final deployment. There is evidence that it is possible to correct WPA3 devices in some cases, and we are not trying to suggest that there is no improvement in security between WPA3 and WPA2 that has not been compromised, but the situation does not seem to be as strong as in the life cycles of previous products.
In all honesty, this is not necessarily surprising. A major review of the firmware of the device over the past 15 years conducted in August revealed essentially zero improvement in security during this time. According to Sarah Zatko, chief scientist of the Cyber Independent Testing Lab (CITL), "No one is trying. We have found no consistency in the fact that a supplier or product line improves or shows improvement. There is no indication that anyone is making concerted efforts to ensure the safety of the products in terms of hygiene. "
In theory, WPA3 should be a major selling point for a product like this, but the overall security issues associated with these devices clearly show that to secure they are of secondary importance for their different designers. It is perhaps not surprising that WPA3 is also a problem.
The first devices supporting Wi-Fi 6 include the Galaxy Note 10, the Galaxy S10 and the three iPhones recently announced by Apple. Most, if not all, of the flagship devices will likely include support from now on.
In early October, Microsoft will unveil the latest hardware for its future Surface products. In recent years, these updates have been generally modest, with some new products (Surface Studio, Surface Laptop) designed to fill various market niches. According to rumors, Microsoft will announce a major change at its October event: a Surface laptop with an AMD chip, rather than an Intel microprocessor.
(D) At a series of corresponding entries in non-public databases of European retailers, we are confident that the new Surface Laptop 3 15-inch model will definitely be equipped with AMD processors … According to the current state, we met three AMD-based models of the Surface Laptop 3 with a 15-inch screen.
If this is true, it would be a major marketing victory for AMD. Area may not have the marketing stamp of Apple, and the Microsoft PC market is not as big as a big OEM, but it would still be a gain of visibility for the APU of the company. At the same time, however, it would be a little surprising. AMD's current range of mobile APUs can name Ryzen 7 3700U and Ryzen 5 3500U processors as class 3000 processors, but it relies on the company's 12nm Zen + designs and not on mobile APUs of 7 nm currently under development. With improved processor performance and power consumption at 7nm, AMD expects the company's current 7nm mobile products to be a significant leap forward. But these parts are not there yet.
Intel's Intel Ice Lake and Intel's Coffee Lake processors are generally faster than the 3700U in a number of direct comparisons, though readers need to be aware of two important factors. First, these systems can have very different prices (PC Perspective compare at 1300 USD, Lenovo AMD system against an Ice Lake of about 1900 USD). Secondly, AMD systems can be designed to slow down their performance. Lenovo AMD systems keep clocks up to 60% faster than HP AMD systems with the same APU, according to one the comparison by NotebookCheck.
Nowadays, this type of stupidity controlled by manufacturers does not weigh on Microsoft products. But it's interesting to see the rumor that Microsoft would use AMD at a junction like this one. About eight years ago there was a persistent rumor Apple had seriously considered using the AMD Llano for an iteration of the MacBook Air. Rumors like this are not uncommon, but this one was stronger than most others. According to sources with whom we spoke at the time, Apple was not interested in the product because it was worried about the long – term roadmap. AMD and its ability to provide iterative editions of the family of processors that would improve thermal performance and performance of Air performance
C & # 39; possible the interest of Microsoft has been stung by the opposite this time. The Ryzen 7 3700U and Ryzen 5 3500U are solid pieces to start with. Although this story is a rumor and deserves to be treated as such, it is not impossible that the Ryzen family reaches at 12 nm a series of price / performance balances that Microsoft has found attractive, especially on the GPU side , where the Ryzen family offers strong assets. performance (Ice Lake has a built-in GPU faster, but is also relatively hard to find). What would be more interesting is that if Microsoft is confident to build a product line based on Ryzen because He estimates that AMD's 7 nm APU family will continue to offer excellent performance scaling.
Even if this is true, we probably will not hear about it on October 2nd, and we do not even know if this first rumor is true. I guess Microsoft will not be a surprise launch product for AMD's new 7 nm APUs. It's not impossible, but I suppose we would have heard if it happened, and there has been no word to date. Whatever the case may be, gaining room in a Microsoft Surface product would be a major win for AMD, producing 12nm or 7nm. The volume of absolute sales may not be huge for a given Surface device, but the gain in marketing would be considerable.
Acer designed his Nitro 5 Gaming Laptops Affordable mid-range solutions for gamers. These systems are available in 15.6-inch and 17.3-inch sizes with different hardware configurations. In this article, I will focus on a larger model of 17.3 inches. Acer has equipped its Nitro 5 gaming laptops with a relatively modest set of features compared to other gaming laptops, but that does not stop them from being solid values overall.
The exterior of the Nitro 5 is entirely made of plastic. The 1080p display of the system simply has a refresh rate of 60 Hz and a color depth of 6 bits. The 17.3-inch model is also quite heavy at 6.6 pounds.
Our sister site PCMag compared a system with an Intel Core i5-9300H processor with four Hyper-Threaded processor cores, as well as an Nvidia GeForce GTX 1650 graphics processor with 4 GB of RAM. Acer has launched 8GB of RAM and a 512GB NVMe SSD. This notebook also has a second unoccupied M.2 slot and additional workspace to add a 2.5-inch drive, making it easy to adding storage if you feel adventurous enough to disassemble the system.
PCMag pointed out that the computer's speakers carried a clear sound even when the volume was up, but, like most speakers, the bass of this laptop is lacking. However, Acer has chosen to mount the Nitro 5 speakers on the bottom, which means that your audio experience will vary greatly depending on the position of the notebook and the type of equipment. Personally, I absolutely hate when laptop makers opt for bottom-mounted speakers, because the speakers mounted next to the keyboard provide a much better and more consistent audio experience.
PCMag has tested this notebook against four other systems. Helios 300 predator of Acer is easily the fastest system tested here and holds easily in advance in each test. Walmart Power play laptop 17+ should have been an easy winner for second place, but, as you'll see in a moment, he's struggling to outdo the remaining systems of the test group.
With the tests with Cinebench R15, the Acer Nitro 5 falls to the last place. Because Dell and Lenovo systems use the same processor, their performance performance over Acer is probably due to higher cooling. Surprisingly, the Overpowered laptop with its Core i7 processor remains just ahead of the slower Core i5. We basically see the same results when testing with Photoshop CC.
The situation remains gloomy for the Acer Nitro 5 when we look at the results of the synthetic tests. The Acer Nitro 5 is no longer in last place, but fourth when tested with the Unigine Superposition 1.0 test, while the Dell competitor system is very similar to the Nitro 5.
The results of 3DMark are more mixed with the Acer Nitro 5 and Dell G5 15 SE in the running for the 3rd place.
In the actual game tests, the Acer Nitro 5 runs a little better. He claims a clear win for 3rd place Far Cry 5. He also remains in third place and maintains a strong lead over the Dell G5 15 Se on the Tomb Raider when tested with very high graphics settings.
Although Nitro 5 gaming laptops can not compete with Acer's more powerful computers. Predator 300 Notebooks, it clearly offers fierce competition against the Dell G5 15 Se. Not only is it competitive in terms of performance, but the Acer Nitro 5 discussed in today's magazine sells for $ 879.99, while the Dell G5 15 Se is usually sold for $ 1,018.99.
The Dell is currently on sale for $ 919.99, but even then it costs $ 40 more for a very similar product. As such, I would recommend Acer Nitro 5 to its competitors based on the conditions and performance of the current market.
Microsoft's efforts to master the problems encountered in Windows 10 1903 continue to turn against the company. Earlier this month, we explained how a cumulative update fix had broken the functionality of Cortana and SearchUI, causing CPU usage spikes and sometimes even Windows Desktop Search. On Tuesday, September 10, Microsoft distributed a new patch designed to address these issues.
KB4515384, this fix is now confirmed as having its own set of problems. According to some information, the Windows 10 Start menu might no longer work with one of the following two error messages: "We will try to fix this problem the next time you connect" or "Critical error: your menu Start does not work. During this time, Windows Desktop Search may continue to display blank results for any query.
"Microsoft has received information that some users may have problems with the Start Menu and Windows Desktop Search," the company said. "We are currently studying and will provide an update as more information becomes available."
There are also reports of audio issues hitting this update. There are various reports of audio missing in games or significantly reduced. Windows Recent marks One way to solve these problems is to reduce Windows Audio to 16-bit DVD quality. To do this, click on the 'Sound' icon in the Control Panel, click on your Speaker / Headphone solution to modify its properties, go to the 'Advanced' tab, then select the 16-bit 48000 Hz option. (DVD quality).
If nothing works, you can always uninstall the update.
And that's where we are today with Windows 10. In fact, I do not even know how important these issues are. What they exist is a given, but how many people do they have an impact? I do not feel as if Microsoft has created a more stable product with Windows 10 – I do not think the updates will keep you from messing up – but is this really what most people are going through? The fact that Windows is updated much more often makes it easier to track various issues that affect the operating system, but does not tell us how many people are affected by these issues.
At the same time, Microsoft continues to have fairly objective problems, at least in terms of the number of people they touch. Not being fully compatible with Microsoft's Surface products is embarrassing enough. Windows should also not need to block its own updates on systems with external storage solutions. We expected this type of problem to be resolved before any update was put into production.
Microsoft has made many significant changes to the way it addresses privacy in Windows 10 and these changes have generally been positive. He collects less data now and has better explained what he does with what he collects. But the much promised improvement to the operating system update model? It did not really happen, at least not to the extent that they promised it. There are still many problems to overcome that do not seem to be needed. I'm tired of using funny images from a used car salesman and poorly designed aircraft. Could you simply repair the operating system?
Over the years, America has had its share of memorable decades in fashion. We had the roaring twenties, the golden era that followed the end of the Second World War, the disco, and so on. Since then, many things have changed, but in the nostalgic respect of the 1980s and Miami Vice, Origin has designed its customized product Millennium Hard Line Vice Edition game desk with a lot of classic neon style.
At first glance, you will like or dislike this case. On the right side, retro artwork on which is engraved "Origin Vice". I'm pretty sure I had a Nintendo game that looked like this before.
The left side of the case has a tempered glass panel with additional illustrations. The system inside seems immaculate and shines like a real neon sign.
Origin built this system with a hard tube liquid cooling system. Transparent cooling blocks are mounted on the processor and on two Nvidia GeForce RTX 2080 Ti graphics cards. These blocks glow blue and the hard tubes that connect them glow purple. The RAM also features specialized headers designed by Origin, which have been complemented by blue and purple LED lights.
With two RTX 2080 Ti graphics cards in SLI and an Intel Core i9-9900K, this system is excessive for a gaming system. Our sister site, PCMag, compared one of these systems to some of the fastest computers ever tested by the site.
The Core i9-9900K inside the Millenium Hard Line Do not eat overclocked. As a result, it ranked second behind the Velocity Micro Raptor Z55 after being tested with the CPU-based Cinebench R15 benchmark.
Since the RTX 2080 Ti graphics cards are relatively new and the Millennium Hard Line Vice has two with a water cooler, the system has easily outperformed the competition in almost every GPU-based test.
PCMag performed additional tests with a custom system with two RTX 2080 Ti graphics cards and an Intel Core i7-8700K processor. Tests against this system showed that the Millennium Hard Line Vice occasionally fell to second place despite its faster processor and superior thermal solution.
If you keep good memories of the 80s and like the look of this case, you can order the system directly from Origin, but you also have better capabilities. The system has an exuberant price of $ 6,557. Although it offers exceptional performance, high-end parts and an expensive thermal solution in addition to the personalized aesthetic, we are now venturing into the silver of used cars. In fact, I only owned four cars in my life and the first three together cost about half the price of this deal.
Realistically, no one needs this level of performance. And if you're not a fan of the '80s, like me, you're not going to like this thing. But to be fair, this system is not targeted as a reasonable high performance solution. It is meant to be a centerpiece for someone who really digs his mood. The system seems to be well designed and works well. If you really like the case, I recommend you buy it.
The expected behavior of AMD 7 nm Ryzen processors at a very high frequency compared to actual measured behavior is one of the most frequently asked questions by reviewers in recent weeks. AMD promised today to inform the user community today about the expected behavior of its processors and the changes that would be incorporated into future revisions to the UEFI.
To summarize briefly: Reports published at the end of July showed that some AMD processors only reached the upper clock frequency boost on a single central unit. Last week, the overclocker Der8aurer released the results of a user survey, which shows that only some The AMD 7nm Ryzen processors reached their maximum (the exact percentage varies depending on the model). Late last week, Paul Alcorn of Tom's Hardware released a thorough test from the impact of different versions of AMD AGESA and UEFI versions of the motherboard on the motherboard pointing. AGESA is the generic architecture of the encapsulated software AMD – the library of procedures used to initialize the processor and various components. Motherboard vendors use AGESA as a template for creating UEFI versions.
What THG found is that different versions of UEFI and AGESA versions have shown slightly different synchronization results. The latest versions have been slightly lower than previous versions used for journals. At the same time, however, these latest versions have also often maintained their recall clocks for longer before slowing down the processor.
It has also been proven that the acceleration temperatures have been subtly adjusted from 80 ° C to 75 before going back to 77. These changes would not necessarily affect performance – the processor increases slightly, but also longer – but that was not the case. And that's exactly what AMD was trying to accomplish. During his IFA presentation last week, Intel argued that these subtle variations were proof that AMD was trying to deal with a potentially important reliability issue with its processors. THG was not willing to subscribe to this explanation without additional information.
While all this was happening, AMD informed us that it would make an announcement on September 10 regarding a new update of AGESA.
The following text is directly from AMD and concerns the improvements that will be made to the updated UEFIs of different motherboard manufacturers. Normally, I do not quote this blog post extensively, but I think it is important to present the exact text of what AMD says.
The analysis indicates that the processor's boost algorithm has been affected by a problem that could lead to lower target frequencies than expected. This has been resolved. We also explored other possibilities for optimizing performance, which can further improve the frequency. These changes are now implemented in the flashable BIOSes of our motherboard partners. Our internal tests show that these modifications can add approximately 25 to 50 MHz to the current boost rates in various workloads.
AMD Reference Motherboard (AGESA 1003ABBA Beta BIOS)
AMD Wraith Prism and Noctua NH-D15S chillers
Windows Update May 10, 2019
Laboratory of ambient tests at 22 ° C
Streacom BC1 open work table
AMD 1.8.19.xxx Chipset Driver
AMD Ryzen Balanced diet plan
Default BIOS (except OC in memory)
These improvements will be available in flashable BIOSes from about two to three weeks, depending on the timing of testing and implementation of the manufacturer of your motherboard.
In the future, it is important to understand how our Boost technology works. Our processors perform intelligent real-time analysis of processor temperature, motherboard voltage regulator current (amperes), socket power (watts), charged cores, and power intensity. workload to optimize performance, from millisecond to millisecond. Make sure your system has adequate thermal paste; reliable cooling system; the latest BIOS of the motherboard; reliable BIOS settings / configuration; the latest AMD chipset driver; and the latest operating system can enhance your experience.
After installing the latest BIOS update, a consumer running a single threaded application on a PC with the latest software updates and sufficient voltage and thermal margin should benefit from the overvoltage frequency maximum of its processor. PCMark 10 is a good proxy for a user who tests the maximum boost rate of the processor in his system. If users run a workload such as Cinebench, which runs for an extended period of time, the operating frequencies may be lower than the maximum throughout the run.
In addition, we want to answer recent questions about reliability. We perform extensive technical analysis to develop reliability models and to model the life of our processors before starting serial production. Although AGESA 1003AB contains modifications aimed at improving system stability and user performance, no changes have been made for reasons of product longevity. We do not expect that boosting frequency enhancements for AGESA 1003ABBA will impact the life of your Ryzen processor. (Underline added).
In addition, AMD also provided information on the firmware changes implemented in AGESA 1003ABBA, intended to reduce the operating voltage of the processor by filtering requests for voltage / frequency increase for light applications. 1003ABBA AGESA now contains an activity filter designed to ignore "intermittent background noise from the operating system and applications." This should reduce the processor voltage to 1.2 v, unlike the higher peaks reported.
Finally, AMD will release a new surveillance SDK that will allow everyone to create a monitoring tool to measure the different facets of Ryzen processor performance. More than 30 API calls will be exposed in the new application, including:
Current operating temperature: Indicates the average core temperature of the CPU over a short sample period. By design, this metric filters transient spikes that can distort temperature reports.
Peak voltage (s) (PCV): Indicates the voltage identification (VID) requested by the CPU package of the voltage regulators on the motherboard. This voltage is configured to meet the needs of cores under active load, but does not necessarily correspond to the final voltage experienced by all cores of the CPU.
Average heart tension (ACV): Reports the average voltages experienced by all processor cores over a short sampling period, taking into account active power management, sleep states, VDROOP, and time of day. inactivity.
CDE (A), CDT (A), PPT (W): Current and power limits for the VRM and CPU socket of your motherboard.
Maximum speed: Maximum frequency of the fastest kernel during the sampling period.
Effective frequency: Frequency of the processor cores after taking into account the time spent in the sleep state (for example, basic sleep cc6 or packet sleep pc6). Example: A processor core operates at 4 GHz when it is awake, but in standby cc6 for 50% of the sampling period. The effective frequency of this nucleus would be 2 GHz. This value can give you an idea of how often cores use aggressive energy management features that are not immediately obvious (for example, clock or voltage changes).
Different voltages and clocks, including: SoC voltage, DRAM voltage, matrix clock, memory clock, etc.
Ryzen Master has already been updated to give the average base voltage values. AMD expects motherboard manufacturers to release their new UEFIs with the 1003ABBA AGESA version built in two weeks from now. As we wrote last week and despite rumors from Shamino, an Asus employee, AMD in no way describes these timing behavior adjustments as reliability-related.
Regarding AMD's statements on improved clocks, I want to wait to see how these changes impact the behavior of our own test processors before drawing any conclusions. I will say that I do not expect to see a lot of changes in overall performance – 25-50 MHz is only an improvement of 0.5 to 1% on a 4.2 processor GHz and we may not even be able to detect a performance change in a standard benchmark from such a change in clock. But we can directly monitor the clock speeds and will report the impact of these changes.
