Update: Wouldn't you know it? Almost as soon as we published this article, Microsoft began pushing out a fix for the L3 cache latency bug that was introduced with the first cumulative (Patch Tuesday) update for Windows 11, and which only affected AMD processors and platforms. This is great news for AMD chip owners. Along with the updated chipset driver highlighted below, the addition of Microsoft's patch (now available via Windows Update) means the performance issues affecting Ryzen processors should be completely resolved. AMD Ryzen 9 5950 L3 Cache Latency With KB5006746 Installed In fact, we installed the new drivers and patch moments after they became available and can confirm that L3... Read more...
We've reported on the performance problems with Ryzen CPUs under Windows 11 a few times now, and produced our own test results to demonstrate the issues. AMD and Microsoft said they had patches forthcoming, and indeed, that seems to be the case. Testers in the Beta and Release Preview channels in the Windows 11 Insider's program will have received build 22000.282 by now, which includes among its myriad fixes a patch for the severely increased L3 cache latency issue on Ryzen processors. In case you didn't see our prior reporting, an unspecified bug in Windows' low-level services, drivers, or kernel somewhere caused L3 cache latency to spike to over triple its value on Windows 10. Such an increase... Read more...
Windows 11 hit the ground running last week—or maybe stumbling, at least on AMD Ryzen-based systems. As we reported at the release of the new operating system, CPUs based on AMD's Zen architecture are seeing drastically-worsened L3 cache latency under Windows 11. Yesterday was the first "patch Tuesday" for Microsoft's new baby, and lo and behold, the issue is... worse? Indeed, after yesterday's updates, users on tech forums have noted that L3 cache latency is even worse for Ryzen systems. TechPowerUp reports that a Ryzen 7 2700X test system went from 10ns in Windows 10 to 17ns latency on Windows 11's release, and yesterday's update increases that figure to an absolutely awful 31.9 nanoseconds....

If you are an enthusiast that recently upgraded from Windows 10 to Windows 11 and have noticed some performance degradation, you’re not alone. Although we’re not sure why these issues didn’t rear their heads earlier during the Windows Insider testing phase, AMD confirms that its Ryzen and EPYC processors are affected by two performance-robbing bugs. The first issue involves L3 cache latency, which can increase by 3x compared to the same system running Windows 10. As a result, applications that are “sensitive to memory subsystem access time” could be affected, resulting in a performance hit of 3 to 5 percent in some applications. However, AMD notes that the performance... Read more...
AMD has witnessed a significant resurgence in the PC market with its Zen-based processors, which currently encompass the Ryzen 5000 family in the consumer space. However, the company is always looking for a competitive edge over its close rival Intel, and a new partnership with MediaTek could advance those efforts. DigiTimes alleges that AMD and MediaTek are looking to form a joint venture that would allow intellectual property from the latter to integrate into SoCs from the former. The two companies have previously collaborated on the standalone AMD RZ608 Wi-Fi chip, which is a rebranded version of MediaTek’s MT7921K. This new partnership would have bolder ambitions by putting MediaTek... Read more...
Heads up for anyone running an AMD build, there is a new chipset driver update available, and you're going to want to install it. The update patches a vulnerability that could allow a user with low privileges to access uninitialized physical memory pages that potential contain sensitive information, including passwords. The vulnerability is tracked as CVE-2021-26333. In a security advisory, AMD explained that the flaw resides in the Platform Security Processor (PSP) chipset driver, and recommends either updating through Windows Update (which bumps the PSP driver to 5.17.0.0) or applying a newer chipset driver (version 3.08.17.735 or later). Security researcher Kyriakos Economou discovered the... Read more...
Late last week, we received the latest market share numbers from Mercury Research regarding AMD's processor market share. Needless to say, the company is performing exceptionally well in both the client and server markets. According to Mercury Research, AMD's share of the overall x86 processor revenue market stood at 16.9 percent for Q2 2021, which was a +0.8 point change compared to the prior quarter and a +7.3 point change year-over-year. In addition, client and server revenue share stood at 15.8 percent and 11.6 percent, up 4.1 and 4.7 percentage points, respectively, compared to the same period last year. With this in mind, we decided to venture over to two of the most popular retail websites... Read more...
Over the last eight months or so, segment by segment, AMD's various Zen 3-based processors have taken the world by storm. High performance servers, desktops, and notebooks all feature AMD's flagship silicon, thanks in no small part to its excellent perf-per-watt and strong overall value proposition. That dynamic really started in 2020, but we could sense a bit of hesitancy on the part of manufacturers with last year's Ryzen 4000 series gaming notebooks, since those topped out with midrange graphics. This year, though, the kid gloves have come off and higher-end graphics options have been made available.  That's especially true with Dell's Alienware gaming brand. Last year, there wasn't a...

We have seen major OEMs tinker with drivers and system settings for workarounds and various fixes in games and other apps before. And now that AMD is firmly back in the mainstream desktop processor race, the company is occasionally under the microscope with power users and developers that stumble onto similar patch type efforts. In that regard, it appears Ryzen systems may pose a potential cause for concern. A researcher has found a seemingly disguised AMD driver toggling certain system behaviors when it detects a list of games, which could open the door to security vulnerabilities and other issues. This past Saturday, security researcher and Windows Internals expert Alex Ionescu was working... Read more...
We are no strangers to Alienware’s Aurora line of gaming PCs here at HotHardware. In fact, we have reviewed many Aurora systems over the years, and for good reason. Aurora desktops embody the essence of a powerful, mainstream prebuilt rig, with semi-custom, almost boutique styling, in a manner that makes them more attainable for the masses. Yet, every time we receive an Aurora in for review, it has something added we have not seen in the family before and this Aurora R10 Ryzen Edition is no exception. Strictly speaking, this is also not the first time we have had an Aurora R10 Ryzen Edition in our lab. Back in 2019, we tested Alienware’s first Ryzen-imbued iteration which housed a... Read more...
AMD reckons it knows why some Ryzen owners are experiencing USB flakiness with motherboards based on a 500-series chipset. And with that knowledge, it plans to roll out a fix. This will come by way of a BIOS update, the timing of which will partially depend on the make and model of your specific motherboard. This primarily has to do with users reporting dropped connections from external peripherals hooked up to a USB 2.0 port. For whatever reason, 500-series motherboards have been having issues in such scenarios, when PCI Express 4.0 is enabled in the BIOS. There was always the option of disabling PCIe 4.0—AMD also offered up a few other potential fixes last week—but that takes away... Read more...

Overclocking a CPU used to be a pretty simple process: change a bus speed or a multiplier, set an appropriate voltage, and voila: your Celeron 300A was running at 450 MHz, or your 600 MHz Duron was knocking on the 1 GHz barrier. These days with the advent of dynamic boost speeds and optimized frequency and voltage curves, processors intelligently push themselves up close to the limit straight out of the box. Setting a multiplier, even if it's higher than the base clock, might actually result in lower performance than stock speeds under certain conditions. The CPUs that likely have the most headroom, those a ways down the chain in Intel's lineup, for example, have locked multipliers and offer... Read more...
This should come as a surprise to absolutely no one who has been paying attention to the tech sector, but AMD is coming off a record quarter of earnings, which contributed to record fiscal year results. AMD capped off 2020 with $3.24 billion in revenue during the fourth quarter, up 16 percent sequentially and 53 percent year-over-year, and raked in $9.76 billion for the full year. That amounts to a staggering 45 percent jump in year-over-year revenue. After paying the bills, AMD was left with a $4.35 billion profit for all of 2020, up 52 percent from the previous year. The company has come a very long way from the days when it used to post quarterly and annual losses with alarming frequency.... Read more...
ASUS Republic of Gamers (ROG) has always been a strong player in the gaming space, especially as CES. This is not going to change at CES 2021 as the company has a number of awesome products in store. With extreme laptops and powerful displays, it is time to get your game on with ASUS ROG… ROG Flow X13/ ROG XG Mobile ASUS Republic of Gamers announced the ROG Flow X13, a 2-in-1 convertible gaming laptop that could change the way people work and game. It features a 13” body packing an 8-core AMD Ryzen 9 5980HS, a dedicated NVIDIA GeForce GTX 1650 GPU, and up to 16GB of LPDDR4X-4266 RAM. It is also only 15.8mm thick and weighs just 2.9lbs, making it a great option for whatever you need... Read more...
We're not sure who needs to hear this at Amazon, be it Jeff Bezos or a warehouse manager, or someone in the shipping logistics group, but for the love of everything that is holy, can you PLEASE stop skimping on shipping materials when sending out AMD Ryzen 5000 series processors that cost several hundred dollars? Pretty please, with a Raspberry Pi on top? Look, we get it—over packaging items is both wasteful and an annoyance. You know, like when ordering a stick of lip balm and it gets shipped out in a box that would have been big enough to hold 100 sticks of lip balm, and could have just as easily been sent in a soft-pack mailer -- like the ones you folks for some reason are also using...

Though Epic Games is giving away games for Christmas, not everything that seems free truly is. Either by lousy design, stealthy data collection, or a combination of the two, the Epic Games Launcher appears to be continuously running some sort of relatively demanding process in the background. This issue is so pronounced that a Reddit user by the name Neoncarbon noticed that his AMD Ryzen 7 5800X idle temps dropped from 50C to 37C when he closed down the app. We actually proved this out for ourselves as well, as you'll see in the screen shots below. What's odd is that other game store apps, like GOG and Steam, do not show this behavior at all. What exactly could Epic Games Launcher be doing in... Read more...
There was little question, when we took a deep dive look at AMD's Ryzen 9 5950X and Ryzen 9 5900X in our launch day review, we came away thoroughly impressed. Not only did AMD deliver on its promise of a significant performance lift in many areas, versus its previous gen Ryzen 3000 series, but we also realized better power consumption characteristics for even better performance-per-watt results than we expected. But let's take a step back. You might recall that a little over a year ago, we trucked on down to scenic Kenilworth New Jersey to meet with our buds at Maingear for a very special all-AMD DIY PC build in Maingear's new Vybe chassis with its oh-so swank Apex Liquid cooling system. Maingear... Read more...
When Cyberpunk 2077 launched earlier this week we knew it would not be a lightweight game, simply by looking at the vast number of available graphics settings and impressive visuals. Moreover, with the sheer NPC and texture density of Night City, frame rates are not always the greatest unless you have the most powerful of graphics cards. However, what’s also surprising is that AMD Ryzen CPU owners may not have noticed the extra performance hit they are taking because Cyberpunk 2077 is not correctly utilizing all core resources of their CPU. Fortunately, there is an easy fix, thanks to some reddit sleuths, so let’s optimize Cyberpunk 2077 for Ryzen processors shall we? First,... Read more...
AMD versus Intel is sort of a David versus Goliath story, only these days, AMD has armed itself with more than just a slingshot. Zen is the real deal. That is abundantly clear by now, but lest anyone needs reminding, a peek at Steam's latest hardware survey results for November 2020 show how well AMD's processors are being received by gamers, as it continues to, uh, chip away at Intel's share. I can hear the groans at the pun, but bear with me. The point is, this is a different AMD versus Intel battle than in past years, before Zen came along. AMD for a long time was the also-ran, while Intel dominated the market with better performing CPUs at the high end. But now? The Ryzen 5000 series is an... Read more...

AMD introduced Precision Boost Overdrive, or PBO, a couple of years back to make extracting additional performance from its Ryzen processors, in systems with additional power and thermal headroom, as simple as a few clicks in Ryzen Master. And today, the company just updated the feature with a couple of new wrinkles to boost performance of Ryzen 5000 series processors even further. Unlike a manual overclock which can lock cores at a particular frequency, with Precision Boost Overdrive SenseMI is left in control of the processor, so frequencies and voltages can still dynamically scale up and down depending on the workload at the time. PBO monitors real-time environmental info from the processor... Read more...
