Intel Sapphire Rapids server example with 8-channel DDR5 memory tested in AIDA64 and Cinebench

Insider YuuKi_AnS shared information about the performance of a technical sample of a 4th generation Intel Xeon Scalable processor with 48 cores and 96 threads and a TDP of 270 W. This processor series, also known as Sapphire Rapids, is used for the Intel Eagle Stream (LGA 4677 ) platform developed.

According to the informant, the chip has an operating frequency range of 2.3 to 3.3 GHz, is equipped with 90 MB of L3 cache and has no integrated HBM memory. This is not a flagship solution for the upcoming Sapphire Rapids line of processors. It will be a 56-core, 112-thread model that is forecast to draw 350 watts of power.

Configuration of two 48-core engineering samples 4th generation scalable Xeon passed the performance test of cache memory and RAM in the synthetic AIDA64 benchmark. It was compared with a system based on two server flagship processors AMD EPYC 7773X (Milan-X) with 64 cores and 128 threads and 3D V-Cache technology and a system based on two Intel Xeon Platinum 8380- Generations with 40 cores based Ice Lake-SP . The informant did not provide data on the memory configuration, but we recall that the platform natively supports DDR5-4800 memory.

It is to be expected that the new Intel platform with 8-channel DDR5 will emerge as the leader in terms of RAM bandwidth. RAM read speed reached 515 GB/s, write speed 317 GB/s and latency 106.4 ns. Sapphire Rapids’ final samples will likely be even better.

At the same time, the AMD Milan-X-based system proved to be significantly more efficient in terms of L2 and L3 cache performance, since each chip is equipped with 768 MB of 3D V-cache buffer memory. Below are also comparative test results of the three platforms in the Cinebench R15 benchmark. As you can see, EPYC wins in multi-threaded performance, but Intel solutions are faster in a single thread.

Sapphire Rapids processors are based on the Golden Cove microarchitecture, known from desktop and mobile Alder Lake chips. Intel 7 (10-nm) technological process is used for their release. Some models will come with onboard HBM storage.
