One of the first tests of Intel Sapphire Rapids server processors appeared on the Web. In this case, we are talking about the AIDA64 memory subsystem test, so we cannot directly say anything about the performance of the processor part from it.

Testing took place on a 48-core CPU. This is an engineering sample with frequencies of 2.3-3.3 GHz, 90 MB of L3 cache and a TDP of 270 W. It does not have its own HBM memory.

A system with two of these CPUs was tested and was opposed by a system with two 64-core AMD Epyc 7773X Milan-X processors with 768 MB of 3D V-Cache.

As you can see, both platforms have their advantages. The AMD solution has much better L2, L3 cache performance, more than eight times the L3 cache performance, and lower latencies. Intel's new offerings offer greater L1 cache performance and faster DDR5 RAM.

Of course, all this has an impact on performance in certain tasks, but still full-fledged tests will still have to wait.
