Download AMD’s new driver now to fix a major Windows 11 bug

A day after Windows 11 launched, AMD posted a notice about two severe bugs that could tank performance as much as 15%. The two issues are resolved now. One fix comes from AMD, while you can obtain the other through Windows Update.

The AMD update is focused on UEFI CPPC2, or in practical terms, AMD’s preferred core feature. The Windows 11 bug wouldn’t put the most demanding work on the fastest core, leading to decreased performance overall. You can download the chipset driver update now (revision 3.10.08.506) from AMD’s website. As a reminder, this update is relevant to all AMD processors that work with Windows 11.

Microsoft just released a patch for the issue that many Windows 11 users are concerned about that can reduce gaming performance as much as 15%. This bug is related to increased L3 cache latency. It’s the lowest level of cache on the CPU, and increased latency means it clogs up data flowing into the CPU and up to the higher levels of cache.

Originally, Windows 11 could nearly double the latency of the L3 cache. Microsoft issued a patch for Windows 11 on its normal Patch Tuesday, and we hoped to see the problem resolved. But the update made the L3 cache latency issue worse, more than tripling the latency in some processors.

Microsoft issued a patch fixing this issue to Windows Insiders on October 15. Now, the patch is rolling out to the general public. To update, use Windows Key + S, search for Windows Update, and select Check for Updates. The build that fixes this issue should be available (KB 5006476). The update is all the more important considering Intel’s upcoming 12th-gen Alder Lake launch. These processors are said to work best on Windows 11, but bugs meant AMD was entering the fight at a disadvantage.

If you have an AMD processor that works with Windows 11, you should install the new patch now. Ryzen 2000, 3000, 4000, and 5000 chips are affected, as well as Threadripper 2000 and 3000, select EPYC server processors, and select Athlon processors.

After downloading the update, AMD recommends users with Zen+ or Zen 2 CPUs (Ryzen 2000 and 3000) set the AMD Ryzen Balanced power plan in the power options. To do that, open the Control Panel, select Power Options, then select Choose Power Plan. You can change your plan there.

Needless to say, Windows 11 isn’t off to a perfect start. However, these two new patches fix two of the biggest problems with the operating system. Microsoft recently released Android apps to Windows Insiders, too, delivering on one of the biggest promises for the new OS.

How to remove a Microsoft account from Windows 11
Windows 11 updates are moving to once a year.

While many people love porting their Microsoft account to their new Windows 11 PC, just as many hate the experience. One of the nicest things about having a new computer is how little tabs it has over you, and letting Microsoft in from the beginning — especially in a way that feels required — is a bit letdown for privacy-minded people.

To make matters worse, getting rid of your account feels tricky. It not only feels like it, Microsoft is your direct antagonist in getting the privacy you want. Luckily, you can make a local account that is disconnected from the rest of your life to gain back the personal feel of your computer. Here's how:

AMD’s new CPUs let you play Cyberpunk without a graphics card
AMD announcing AMD Ryzen 8000G.

AMD just revealed its new lineup of desktop APUs with built-in graphics at CES 2024: the Ryzen 8000G series. According to AMD, the Ryzen 8000G lineup can run AAA titles without requiring a discrete GPU. Will these CPUs really rival some of the best processors when it comes to graphics performance? Here's everything we know.

Equipped with AMD's Radeon 700M graphics, these chips combine a CPU and a GPU, and AMD claims that the integrated graphics can compete against some of the most popular discrete graphics cards.

Please, don’t buy an AMD GPU right now
RX 7900 XTX slotted into a test bench.

It's basically a foregone conclusion that Nvidia is launching new Super GPUs next week at CES. We have no official announcement from Nvidia, outside of a keynote presentation at the event, but a mountain of evidence shows that Team Green may be gearing up to launch three new graphics cards. But what about Team Red?

We have heard murmurs that AMD is set to launch a budget-focused RX 7600 XT soon, but the rumor mill has been quiet about a slate of new graphics cards. Even with a pile of graphics cards in stock at reasonable prices and few indications that AMD is going to upend its GPU lineup, it's best to wait a couple of weeks before picking up a new AMD GPU.
Super AMD GPUs? Unlikely
