But we are talking about 1080p here. This resolution is more dependent on CPU performance due to the speed at which the GPU can render frames. Each frame issued by the GPU must be followed by the processor. So naturally, at 1080p, where frame rates are often in the hundreds, your CPU can have more of an impact on your overall performance as it tries to keep up with your multi-threaded GPU.
Testing or benchmarking a CPU at 1080p is a great way to get an idea of the performance differences between the two, but it’s also true that games tend to get much more GPU-limited in their performance the more pixels you use.
|Ryzen 7 5800X3D||Ryzen 9 5900X|
|Boost clock (GHz)||4.5||4.8|
|Base frequency (GHz)||3.4||3.7|
|Process node||TSMS 7nm||TSMS 7nm|
|L3 cache (MB)||96||64|
|L2 cache (MB)||4||6|
The reality is that you should buy a more expensive processor for more cores, more bandwidth, and better single-threaded and multi-threaded performance. It should be a more holistic purchase.
And it must be said that with the Ryzen 9 5900X, you get a lot more than just gaming performance. It has four more cores and eight more threads at its disposal, and those I will make a difference if you use your computer for many multi-threaded applications or resource-intensive workloads such as video editing or 3D model building. GPU acceleration is commonplace today, but there are still many cases where simply using more cores to solve a problem produces better results.
And I think that’s the reason why I’m still leaning towards the Ryzen 9 5900X here – I’m not too leaning into the argument about sacrificing cores to increase L3 cache just yet. It’s not that the Ryzen 7 5800X3D isn’t as interesting as a concept – 3D V-Cache seems to be the future – but that thanks to recent discounts, the Ryzen 9 5900X offers deals that are hard to pass up at this price.
The same can be said for the Ryzen 7 5800X, which is now available for $349. You might argue that without much need for a lot of cores, you can just save money and chips that can be used for a better graphics card instead. It’s definitely money well spent if you can manage to boost your GPU’s performance and increase your frame rate significantly.
There is something else that I am also a little afraid of. I don’t want to go overboard with the unknown amount in Zen 4, but it’s worth considering as it’s due later this year.
The 5800X3D is a test case for 3D V-Cache technology, and as with AMD’s other early technology test case, the Radeon VII graphics card, we’ll likely see the red team outperform this particular chip pretty quickly. The first generation RDNA architecture outperformed the Radeon VII on release and at a lower price point. AMD’s upcoming CPU architecture, Zen 4 will likely do the same with the Ryzen 7 5800X3D.
