AMD has once again cooled down its backward compatibility program and will offer customers who purchase a Ryzen 3000 processor without an APU-compatible motherboard a way to update their systems. This program, in place for several years, is a solution to the recurring problem of processor / APU upgrades that are not backwards compatible with older motherboards.
Let us be clear: this question has existed for a long time and has existed for decades. When CPU designers issue new CPUs, UEFI / BIOS updates are still needed to support new chips. The reason we address this topic several times during the Ryzen era is that AMD has focused on compatibility with earlier versions of Ryzen. This means that more processors have been launched for older platforms, which increases the chances of encountering this problem.
That said, AMD customers may have reasons to prefer the older chipsets of the Ryzen 7 3000 family, which makes this offer important. We were investigating the power of third-generation Ryzen and the associated power of the X470 and X570 motherboards since before the release of the Ryzen 7 advisory. Although the X570 motherboard family offers new features, such as load of PCIe 4.0, these cards consume more energy than the X470 family.
The gap may be important in some cases, which means that the X470 may be a better choice for customers who want to build the most powerful and efficient system possible. But it also introduces the possibility that you end up buying a motherboard that would not be compatible with the latest processors because it was stored before the chips were launched.
If you need a processor to perform the UEFI update, AMD will ship you, you have made a valid purchase of a 3rd generation Ryzen processor and you can not boot the motherboard due to a problem with UEFI update. Send AMD to the photo of your CPU (with visible serial numbers) and a copy or summary of the communication with the manufacturer of your motherboard to indicate why the OEM support will not solve the problem. AMD help page It offers several options that can help users solve the problem without the need for a new processor, but their operation depends on whether the motherboard supports features like UEFI / BIOS flashback.
AMD will send users an Athlon 200GE with prepaid return shipping to complete the update. The processor must be returned within 10 days, but users are free to keep the thermal solution provided if they wish. Those who need to request a kit can do it here. Enter the serial number of your CPU in the product details and enter the phrase "Required Starter Kit" (without quotation marks) in the "Problem Description" field.
Intel has announced a significant advance for its neuromorphic research processor, named Codehi. The company has now extended its implementation of Loihi to 64 processors, allowing it to create a system with over 8 million neurons (8.3 million). This new configuration (codenamed Pohoiki Beach) delivers 1000 times better performance than conventional processors in applications such as sparse coding, graph search, and constraint satisfaction problems. Intel says the new Pohoiki range offers 10,000 times more energy efficiency than conventional processor architectures in this type of test.
Neuromorphic Computing is a subset of the computer that attempts to imitate the architecture of the brain with the help of modern technological analogues. Instead of implementing a typical CPU clock, for example. Loihi is based on a peaked neural network architecture. The basic Loihi processor contains 128 neuromorphic cores, three Lakefield processor cores (Intel Quark) and an off-chip communications network. Theoretically, Loihi can handle up to 4,096 on-chip cores and 16,384 chips, although Intel has announced that it does not intend to market a design of this size.
"Thanks to the Loihi chip, we were able to demonstrate a power consumption 109 times lower than that of a real-time graphics processor, and a power consumption 5 times lower than that of an inference material. IoT specialized, "said Chris Eliasmith. CEO of Applied Brain Research and Professor at the University of Waterloo. "Even better, while the network is multiplied by 50, Loihi retains performance results in real time and uses 30% more power, while the IoT hardware consumes 500% more power and is no longer in time. real."
The implementation of Pohoiki Beach is not the largest deployment planned for the neuromorphic chip. Intel announces its intention to roll out an even larger concept, dubbed Pohoiki Springs, which will offer "unprecedented levels of performance and efficiency for enhanced neuromorphic workloads."
We covered the advances and research in neuromorphic computing for several years at ET. The work done on these processors is closely related to the work done in AI and the machine intelligence in general, but it's not just about how to perform AI / ML workloads. on existing chips. The ultimate goal is to build processors closer to the human brain.
One of the quirks of computing is that the analogies between the functioning of the human brain and the operation of computers are widespread. Human brains and conventional computers do not overlap very little on their functioning. Transistors are not equivalent to neurons and the pulsed neural network that Loihi uses to transmit information about his own processor cores is intended to be closer to biological processes that humans and other animals use than traditional silicon.
Projects like this one have several long-term research goals, but one of the most fundamental is to better understand how the brain works to replicate some of their energy efficiency. The human brain operates at around 20W. The Exascale supercomputer, considered the minimum for advanced neural simulation of anything more complex than an earthworm, should consume megawatts of power per supercomputer. The difference between these numbers explains why we are primarily interested in the long-term energy efficiency and computing potential of the brain. Architectures such as Loihi are not just an effort to write programs that mimic what humans can do. the goal is to copy aspects of our neurology as well. This makes their progress a little more interesting.

If you own Ryzen 3000 (or plan to become one soon), be aware that Bungie's popular MMO Destiny 2 does not currently work on the latest AMD processor. The reason this is the case currently is not clear, but according to the developer, a fix is in progress. However, an update of the motherboard will be necessary to solve the problem.
AMD has identified the problem affecting the ability to run Destiny 2 on Ryzen 3000 processors and has implemented a BIOS patch distributed to partners. In the coming days, players will be able to download the updated BIOS from their motherboard vendors.
– Help Bungie (@BungieHelp) July 12, 2019
The problem appeared a few days ago when Ryzen 3000, the first correctors, discovered that they could not run the game. A week ago, Redditor Trinsikk posted:
Destiny does not work on PC with the new processors of the Ryzen 3000 series. After clicking on the battlenet play button, the game is running and the Destiny 2 executable will show up in the task manager, but it only states that it uses 5 to 10% of the CPU, but never starts. Some discussions have appeared on the bungie forums and this seems to affect all variants of the mother / ryzen 3000 configurations. I have tried to reinstall Windows 3 times with full formats and reinstall the drivers each time. Bungie Halp.
It's not unusual to have some bugs to eradicate, but it's a little unusual: we do not remember the last time the UEFI update was required to eject the bugs of a specific game. In this case, there may be a problem with the way the instructions are issued on the AMD processors. according to Michael Larabel, there are signs of Linux hiccups on new AMD processors also, and the new processors have problems starting some Linux distributions. It seems possible that the problems are related. If this is the case, the updates to the motherboard should solve the problem.
AGESA updates have been shown to improve both the performance and compatibility of Ryzen processors. At the first launch of Ryzen, AMD stated that gaming performance and overall compatibility would improve over time. That was indeed the case – our initial Gigabyte board that we tested in 2017 on Linux until later updates solved the problem, and the overall performance of the first-generation Ryzen improved. with time. When we looked at CPU performance later in 2017, we found that he had picked up speed in several tests.
The situation with the X570 has been much better. AMD's single-threaded overall performance is stronger with the Ryzen 3000 family than it was when the first generation debuted, but there are obviously some compatibility issues to be resolved. If you're a Destiny 2 player, watch for updates to the vendor support page on your motherboard.
The start-up Tachyum has raised $ 25 million during a series-A roundtable for a new processor concept dubbed Prodigy Universal Processor. Prodigy is supposed to be faster than Xeon in single-threaded code, with processor cores smaller than ARM. It can be used to simulate neural networks the size of a human brain in real time. It surpasses Google's processors, GPUs and TPUs. It can run 64 cores at a frequency of 4 GHz, fits in only 290 mm2 disk space (two times less than AMD Epyc 7 nm design on the same node), supports eight channels of DDR5, 72 PCIe 5.0 channels, two 400G Ethernet connections and supports HBM3 .
To say that Tachyum did not prove these claims would be a euphemism. Claiming to be able to beat Intel or AMD in single-thread performance or ARM on the size of the matrix and energy efficiency would raise the eyebrows in the best circumstances. Claiming to do both simultaneously with a chip that you have not yet built requires even more evidence that we have not taken the argument seriously. The company is claim it will eventually set up a processor with 128 cores at 4 GHz in a single socket with 12 DDR5 controllers.
To say that you have solved the problem of "slow threads" (it is probably a reference to the CR delay) with very short threads actually does not respond to anything at all. In particular, it explains nothing about how Prodigy manages to use these very short wires in the critical path, why it is able to deploy them while other competing processors designs can not, or what Tachyum has traded in exchange for short lengths of thread. The total frequency of 4 GHz in a 180 W TDP raises questions about the volume of work that these chips can accomplish per clock cycle, all the more so as they seem to borrow certain pages from the Itanium-based approach to improve hardware performance, ie the idea of execution can be inserted into the compiler and left to to rot effective optimization.
The company made a presentation to Hot Chips last year now public; We have reproduced some of his slides in the slideshow below.
Tachyum PR copy claims that Prodigy reduces the total cost of ownership of the data center by 4 times thanks to a disruptive hardware architecture and an intelligent compiler that has redundant many parts of the hardware of a typical processor. With a smaller, simpler core, fewer wires and shorter wires result in significantly higher speed and energy efficiency for the processor. "
According to the question and answer session after Hot Chips, these processors lose 40% of performance when running native x86 code, which seems to be a major problem for the whole "Faster than Xeon" argument. The company claims that "4.0 GHz binary emissions still outperform Xeon's performance at 2.5 GHz", which would pose more problems to Intel (or AMD) if a 2.5 GHz Xeon represented a kind of threshold objectively difficult performance. Phrases like "Order Execution in Software" are an elegant way to say, "We've done all the work to get high performance in the compiler, and we really hope our compiler can extract enough performance to that it works. "Intel tried exactly that strategy with Itanium. It did not work.
That said, there are a lot of things on Prodigy's architecture that are unclear at the moment. There are arguments in various forums about how well it looks like Itanium or about the best interpretation of its architecture as VLIW, modified VLIW, EDGE or something else.
Tigyum's Prodigy, based on what we've seen up to now, is very long on sizzling. It is supposedly the best parallel processor and the best serial processor, despite the fact that CPUs and GPUs run very different code types. It can match or surpass Intel's high-end chips, while operating in larger electrical envelopes and die sizes than anything ARM or AMD can achieve.
Extraordinary demands require extraordinary evidence. We do not have a lot of that for the moment.
If you have calculated long enough, it is likely that you have already seen strange things. For example, I had an HP printer that – and I swear to God, I'm not kidding – would only print if it were off. It would remain under siege, placidly mocking your attempts to send print jobs to its damn file, until you press the power button to turn off the printer. Once disabled, the bubbly ink beast will print a single document. If you had to print multiple documents, you had to turn on and off the printer between each document. This problem persisted during the installation of several operating systems and several motherboards.
One of the rumors I remember hearing about Windows 95, long ago, that moving the mouse during long installations of applications could increase the speed of your computer. installation. This still seemed slightly ridiculous, although the idea that your mouse has an impact on system performance is not what anyone who has ever tried using a USB 1.0 mouse can attest to it. In the early days of USB 1.0, it was possible that mouse clicks interrupt your processor and so that your mouse does not react when your processor is under a heavy load. Moments of pleasure.
This is due to a flaw in the way Windows 95 generates events and the fact that many applications are driven by events.
Windows 95 applications often use asynchronous I / O, that is, they request an operation on the file, such as a copy, and tell the operating system that they can be paused until the end of this operation. While sleeping, they allow other applications to run, instead of wasting computing time to continually ask if the file operation is complete.
For reasons that are not entirely clear, but probably because of performance issues on low-end computers, Windows 95 tends to bundle messages related to I / O completion and does not wake up immediately the application to repair them. However, it activates the application to allow the user to enter it, to give it an impression of responsiveness. When the application is enabled, it also handles pending I / O messages.
So, if you move the mouse, the application processes I / O messages faster and installs faster. The effect was quite pronounced; Large applications that might take an hour to install could be reduced to 15 minutes with proper mouse input.
It would seem that if we observed this effect in action probably depended on how the installer was written, but the fact that there was a real effect at first is rather hilarious. Even today, this kind of thing is not completely unknown. In the PC version of the original Dead Space, the reload rate of your recorded game is directly related to the frame rate of the game. If you want to load games faster, disable V-Sync (this may require Nvidia Inspector , I do not remember it honestly). I found this problem myself and tested it years ago. If it takes 45 seconds to load a saved game with a locked frame rate of 30fps and you start the game at 240fps unlocked, loading your game takes 5 to 6 seconds. My theory of work is that the game only performs a certain amount of I / O work per image and that it is hard-coded into the engine. Speed up the frame rate and speed up I / O.
This is not exactly the same as this old Windows 95 problem, but it's a similar idea. Does anyone have another type of random, surprising or interesting computer hardware?
