Despite the fact that the Intel Sapphire Rapids-SP is not expected to be available until later this year. multiple Xeon CPUs have leaked in various benchmarks. In terms of cache and memory speed, the current testing put the Xeon processors against AMD’s Milan-X components. Cache & Memory Benchmarks Leak: Intel Sapphire Rapids-SP Xeon vs. AMD EPYC 7773X Milan-X Server CPUs
Furthermore, the leaker has posted updated V-Ray and Cinebench benchmarks comparing the three server processors. This variant is just slightly slower than the flagship model, which has a 1.6 GHz base clock. Also a 3.6 GHz boost speed over a single core. The Intel Sapphire Rapids-SP Xeon CPU will also have 56 cores and 112 threads, a 105 MB L3 cache, with a TDP of 350W. In a dual-socket configuration with 96 cores and 192 threads , the processor was compared against Intel’s Xeon Platinum 8380 (Ice Lake-SP) and AMD’s EPYC 7773X Milan-X CPUs.
The AMD EPYC 7773X Milan-X CPUs are equipped with 64 cores and 128 threads, plus, as DDR4-2866 memory. The memory types of the Ice Lake-SP and Sapphire Rapids-SP Xeon CPUs are not stated; nonetheless, the former should support DDR4-3200 and the latter should support DDR5-4800.
The AIDA64 Cache & Memory benchmark put the chips through their paces. The Intel Sapphire Rapids-SP Xeon CPUs surpass AMD’s EPYC Milan-X and Intel’s Ice Lake-SP processors in terms of memory and latency when using an 8-channel interface. Although the CPU cache latency is very impressive, Milan-X succeeds in the L3 cache test.
The EPYC Milan-X CPUs feature a slight increase in total latency, although having better performance overall, as was already stated. The Ice Lake-SP components have cores tuned at a considerably higher clock speed of 2.30 GHz. The Intel Sapphire Rapids-SP Xeon CPU performs up to 9% faster in the Cinebench R15 tests despite having 22.5 percent more cores. The final version of the ES chip could be quicker and is not far behind AMD’s EPYC 7773X Milan-X CPUs. Despite AMD’s higher frequency advantage, single-core testing shows that the Sapphire Rapids-SP chip outperforms the Milan-X CPU by 26%.
While the Intel Sapphire Rapids-SP Xeon CPU scores wonderfully in these tests, especially in the ES state Remember that the lineup will be competing against AMD’s EPYC Genoa rather than EPYC Milan-X. So team red will still have a big advantage over team blue.
