A rare sight: an Intel processor is much faster than a comparable AMD CPU. 36-core Xeon 8351N showed itself in tests

Already on April 6, Intel will fully introduce Xeon Ice Lake-SP server processors, but now we can see what such a CPU is capable of.

In this case, the tests are interesting for two reasons at once. Firstly, the 36-core model passed them, and this is already a direct confirmation that the top-end CPUs of the line will definitely be models with more than 32 cores. Secondly, the tests were using AVX-512 instructions. Recall that AMD Epyc processors do not support these instructions either in the past or in the new generation, which means that Intel CPUs should be faster in the corresponding tasks.

As you can see, it is, but so far only in comparison with the already previous generation of Epyc Rome processors. In particular, in SiSoft Sandra arithmetic tests, the 36-core Xeon 8351N is faster than all 32-core Epyc by about 19%, and the Xeon 8352N outperforms the new product by 8%. However, this may not seem enough, given the 6% higher frequencies and 12% more cores.

But in multimedia tests, the new Xeon 8351N looks much better. Here it is ahead of its predecessor by 13%, and AMD processors – by about a huge 60%.

True, you need to remember that the third generation Epyc (Milan) has already been released. In addition, AVX-512 instructions are not always needed, and besides, applications with their use load the CPU much more, which significantly increases power consumption and heating.
