Intel Sapphire Rapids-SP Xeon ES CPU’s performs admirably well against AMD’s EPYC 7773X Milan-X Chips in the new Benchmark test

Although the Intel Sapphire Rapids-SP is slated to be released later this year, numerous Xeon CPUs have leaked in various benchmarks. The latest bars pit the Xeon chips against AMD’s Milan-X parts in cache and memory performance.

YuuKi AnS has leaked the newest benchmarks for the Intel Sapphire Rapids-SP Xeon and AMD EPYC Milan-X CPUs. The leaker was the first to get his hands on engineering samples of the Xeon Sapphire Rapids-SP series, and the latest chip he received is a 48-core, 96-thread part with a 270W TDP and clock rates of 2.30 GHz base and 3.30 GHz boost.

The processor has 90 MB of L3 cache and a single-core boost clock of 3.60 GHz. The CPU is a D0 revision ES chip with a QSPEC of ‘QYFQ’. This model is just behind the flagship model, which has a 1.6 GHz base clock and a 3.6 GHz boost speed across a single core. The Intel Sapphire Rapids-SP Xeon CPU will have 56 cores and 112 threads, a 105 MB L3 cache, and a 350W TDP. The processor was compared to 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 and DDR4-2866 memory. The Ice Lake-SP and Sapphire Rapids-SP Xeon CPUs’ memory types aren’t 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 chips in terms of memory and latency. The CPU cache latency is likewise impressive, but Milan-X emerges victorious in the L3 cache testing.

The Intel Sapphire Rapids-SP Xeon CPU is up to 9% faster in the Cinebench R15 evaluations. While it does feature 22.5 per cent more cores, they are clocked at a significantly lower clock speed of 1.50 GHz against 2.30 GHz for the Ice Lake-SP components.

The ES chip isn’t far behind AMD’s EPYC 7773X Milan-X processors, and the final version could be faster. The Sapphire Rapids-SP chip surpasses the Milan-X CPU by 26% in single-core tests despite AMD’s frequency advantage.

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 launches, so team red will still have a significant advantage over team blue.
