Sapphire Rapids-SP Xeon CPU（ chart via Cnet）
It was revealed that the one on hand was 48 The core / 96 Engineering samples of threads , Have 90MB Three level cache . Thermal design power consumption （TDP）270W,QSPEC by QYFQ / D0 Stepping .
Base frequency 2.3 GHz / Single core Rui frequency is the highest 3.6 GHz（ Whole nucleus 3.3 GHz）, However, considering that it is still an early engineering sample （ES）, The parameters here are not of great reference significance .
B Station news （ Portal ）
With the flagship of the series （ Basic screen 【 frequency 1.6 GHz / Single core Rui frequency is the highest 3.6 GHz） comparison , This piece ES edition CPU Is second only to it .
You know Intel by Sapphire Rapids-SP Xeon CPU Provides up to 56 The core / 112 Thread options , supplemented 105 MB Three level cache @ 350W TDP .
The test platform adopts a two-way scheme （ A total of 96C / 192T）, And with Intel Xeon platinum 8380（Ice Lake-SP） and AMD Xiaolong 7773X（Milan-X） The competitive products are compared （ Both are two-way platforms ）.
EPYC 7773X Have 64C / 128T Threads , collocation DDR4-2866 Memory . Although the informant did not mention Ice Lake-SP and Sapphire Rapids-SP Memory type of the platform , But both support DDR4-3200 / DDR5-4800 .
And then in AIDA64 Cache and Memory Benchmark project ,Sapphire Rapids-SP Xeon CPU With the advantage of eight channels , Achieved relatively EPYC Milan-X and Ice Lake-SP Better memory and latency performance .

But it should be pointed out that , Even though Sapphire Rapids-SP The delay data is bright , but Milan-X stay L3 The advantages of caching are also quite significant （ Delay is a little worse , But the overall performance is better ）.
Cinebench R15 Productivity benchmarking ： Although this one ES edition Sapphire Rapids-SP The core frequency of Zhiqiang processor is Ice Lake-SP Much lower （1.5 vs 2.3 GHz）, But there are more in the kernel 22.5% Under the circumstances , It has achieved 9% Leading edge .
Whereas ES The chip has been connected with EPYC 7773X“Milan-X” On a par , We can expect the official version to bring more surprises .
Even if the frequency of the latter is higher , But in terms of single core performance ,Sapphire Rapids-SP With as much as 26% The advantages of .
As for whether the official chip can be connected with AMD new generation EPYC Genoa Competing products , Please wait and see .
