Cinebench and Blender
Cinebench R23 Multi-Core
Of course, we have to test Cinebench R23 starting with Multi-Core performance. It’s no surprise the Ryzen 9 5900X is a lot faster here, 35% faster than the Intel Core i9-11900K with Adaptive Boost turned on. You just can’t overcome the core count here. The Intel Core i9-10900K is the second fastest with its higher core count.
Interestingly though, with Adaptive Boost enabled the Intel Core i9-11900K is not too far away from the older i9-10900K. This shows that its newer architecture is superior to the previous generation. The Intel Core i9-11900K with Adaptive Boost also is faster than the Ryzen 7 5800X. However, without Adaptive Boost (which is the default) it’s pretty much just on par with the 5800X.
Cinebench R23 Single-Core
Testing single-core tends to lend more to CPU frequency, and this is why we see the Intel Core i9-11900K on top here. It’s actually quite a bit faster than the older i9-10900K by 23% which is pretty huge for single-core performance uplift. It’s also slightly faster than the 5800X and 5900X.

Remember, here we are looking for the lowest result. The less time it takes to render, the fastest it is, and the better you’ll be. Nothing beats the Ryzen 9 5900X here, with its core and thread advantage it rips through this render in 1 minute and 54 seconds. The i9-10900K is next, as it also has a higher core count. Then, it looks like the new Intel Core i9-11900K is faster than the AMD Ryzen 7 5800X in this render. It completes it faster, even without Adaptive Boost. That’s actually quite good, but remember the i9-11900K is competing by price with the Ryzen 9 5900X.

The Ryzen 7 5800X and Intel Core i9-11900K are very close, practically the same, with Adaptive Boost off. When you turn on Adaptive Boost the i9-11900K takes a slight lead, but not by much. Once again though, keep in mind that by the price the i9-11900K is competing with the Ryzen 9 5900X, and they just aren’t in the same league at all performance-wise.
