NVIDIA has released a new version of its graphics card driver (in beta) to correct poor performance seen on some PCs when upgrading to the latest version of Windows 11.
In a post on its support page, NVIDIA acknowledges the issue: “Some users may notice slower performance in games or applications after upgrading to Microsoft Windows 11 2022 Update .”

NVIDIA has taken quite a short time to update its drivers to solve the problem. The published driver is in beta, but it works without problems according to our own tests. If you want to install it you can do it in two different ways :
A- Manually download the GFE.3.26.0.131 driver from the official NVIDIA website. Once downloaded, proceed with the installation as with any other executable for Windows.
B- Open the GeForce Experience app and go to Settings. Select “Enable Experimental Features” and close the app. Wait a minute, reopen it, and you will see how the application will automatically install the new version with the fixed problem.
The Ryzen 9 7900X and Ryzen 7 7600X are two of the most anticipated processors in the Ryzen 7000 series, whose presentation took place on August 30. It was undoubtedly one of the most important events in the technology sector, and it is perfectly understandable, not in vain we speak of a generation that picks up the witness of the Ryzen 5000, and that has to face two important challenges: overcome the bar that they have left these, and frankly, it has been very high, and show that they have what it takes to lead the field of high-performance general consumption x86 CPUs.
I am not going to lie to you, after writing so much about the Ryzen 7000 I really wanted to be able to try them, and thanks to AMD Spain I have been lucky enough to receive not one but two units, the Ryzen 9 7900X, which is a high- end model, and the Ryzen 5 7600X, which positions itself directly in the mid-range and succeeds the legendary Ryzen 5 5600X, one of the best gaming processors AMD has launched so far.
AMD has completely changed the design of the box in the Ryzen 7000
At first glance, we might think that there are no major changes since the Ryzen 9 7900X has 12 cores and 24 threads, the same as the Ryzen 9 5900X, and the Ryzen 5 7600X has 6 cores and 12 threads, the same amount as the Ryzen 5 5600X, but nothing could be further from the truth. Both processors bring profound changes at the microarchitecture level, are manufactured in a more advanced node, and are integrated into the latest generation platform.
The changes introduced by the Zen 4 architecture have made possible an increase in the IPC which, according to AMD itself, is 13% compared to the Ryzen 5000. This means that a Zen 4 core running at the same working frequency as a core Zen 3 performs 13% more. However, if we add to this the increase in working frequencies, we see that single-thread performance has increased by 29% compared to the Ryzen 5000. Impressive, without a doubt.
AMD has kept the MCM design in the Ryzen 7000, which means that the CCD unit is once again the central pillar and the I/O chip is still present. The first one is made in a 5nm node, and the second one uses a 6nm node. TSMC has been the “cook” for both, as our regular readers will remember, and all those chip lets are interconnected through the Infinity Fabric system.
With this comparison, we are going to discover in a direct and simple way what are the key differences that exist between both processors. We are not going to delve into details at the level of architecture or performance since we will talk about it later, we will only see its specifications to have the first contact with its characteristics and differences.
Zen 3 architecture, manufactured on TSMC’s 7nm node.
Two CCD Windows units with 8 cores each and SMT technology, which allows handling one process and one thread per core.
12 cores and 24 threads at 3.7GHz-4.8GHz, normal and turbo mode.
64 MB of L3 cache (32 MB per CCD unit) and 6 MB of L2 cache (512 KB per core).
105-watt TDP.
Compatible with DDR4 and PCIe Gen4 memory.
Support overclock.
It uses the AM4 socket and is compatible with motherboards equipped with the 300, 400, and 500 series chipsets.
Does not have an integrated GPU.
- Zen 4 architecture, manufactured on TSMC’s 5nm node.
- Two CCD units with 8 cores each and SMT technology, which allows handling one process and one thread per core.
- 12 cores and 24 threads at 4.7 GHz-5.6 GHz, normal and turbo mode.
- 64 MB of L3 cache (32 MB per CCD unit) and 12 MB of L2 cache (1 MB per core).
- 170-watt TDP.
- Compatible with DDR5 and PCIe Gen5 memory.
- Support overclock.
It uses the AM5 socket and is compatible with motherboards equipped with the 600 series chipsets.
AVX512 instructions.
It has an integrated Radeon RDNA2 GPU with two Windows units (128 shaders).
The differences between both processors are notable and are clear at a glance. The Ryzen 9 7900X uses a more advanced node, supports next-generation technologies and standards, comes with an integrated GPU, which gives it more value at a functional level, and increases the CPU’s working speed by 1 GHz in base mode. and at 800 MHz in turbo mode, two impressive values explain that great improvement in single-thread performance that we referred to, and that show that AMD’s chipset design has matured like fine wine
The use of DDR5 memory will also represent a significant increase in performance, in fact we have already begun to see it in some games, such as Spider-Man Remastered, for example, and compatibility with the PCIe Gen5 standard will allow us to enjoy a wide higher bandwidth both with graphics cards and storage units compatible with said standard.
We can also see one of the most important changes at the microarchitecture level that Zen 4 has introduced, the increase in the L2 cache, which becomes 1 MB per core, and we must not forget that the jump to the 5nm node has allowed AMD to reduce the size of the transistors. This has made it possible for CCD units to have higher transistor density despite being smaller than Zen 3.
