Although the Intel Sapphire Rapids-SP is slated to be released later this year, numerous Xeon CPUs have leaked in various benchmarks. The latest benchmarks pit the Xeon processors against AMD’s Milan-X components in terms of cache and memory performance. Benchmarks Leak In Cache & Memory Tests: Intel Sapphire Rapids-SP Xeon versus AMD EPYC 7773X Milan-X Server CPUs
In addition, the leaker has uploaded updated V-Ray and Cinebench benchmarks that compare the three server processors. This model is just behind the flagship model, which has a 1.6 GHz base clock and a 3.6 GHz boost speed over a single core. The Intel Sapphire Rapids-SP Xeon CPU will have 56 cores and 112 threads, as well as a 105 MB L3 cache and a 350W TDP. The processor was compared against Intel’s Xeon Platinum 8380 (Ice Lake-SP) and AMD’s EPYC 7773X Milan-X CPUs in a dual-socket configuration with 96 cores and 192 threads.
The AMD EPYC 7773X Milan-X CPUs provide 64 cores and 128 threads, as well as DDR4-2866 memory. The Ice Lake-SP and Sapphire Rapids-SP Xeon CPUs’ memory types are not specified, however, the former should support DDR4-3200 while the latter should support DDR5-4800.
The chips were put through their paces in the AIDA64 Cache & Memory benchmark. With an 8-channel interface, the Intel Sapphire Rapids-SP Xeon CPUs outperform AMD’s EPYC Milan-X and Intel’s Ice Lake-SP processors in terms of memory and latency. The CPU cache latency is likewise impressive, but Milan-X emerges victorious in the L3 cache testing.
The EPYC Milan-X CPUs have a little increase in total latency, although as previously said, overall performance is superior. The Intel Sapphire Rapids-SP Xeon CPU is up to 9% quicker in the Cinebench R15 evaluations, and while it does feature 22.5 percent more cores, these cores are tuned at a significantly lower clock speed of 1.50 GHz against 2.30 GHz for the Ice Lake-SP components. The ES chip is not far behind AMD’s EPYC 7773X Milan-X processors, and the final version might be faster. Despite AMD’s frequency advantage, the Sapphire Rapids-SP chip surpasses the Milan-X CPU by 26% in single-core testing.
While the Intel Sapphire Rapids-SP Xeon CPU performs admirably in these tests, especially in the ES state, we must keep in mind that the lineup will be fighting against AMD’s EPYC Genoa rather than EPYC Milan-X when it releases, so team red will still have a significant edge over team blue.
