After being delayed last summer, we now have an idea of how Intel’s upcoming Sapphire Rapids processors will compare to its own Ice Lake Xeon Platinum 8380 and AMD’s EPYC 7773X (Milan-X) chips.
As reported by Tom’s hardwarehardware leaker YuuKi-AnS tested the three processors in dual-socket configurations and posted the benchmark results on Twitter.
Intel’s upcoming Sapphire Rapids line features a multi-chip design with EMIB connections and comes from the chipmaker’s rebranded 10nm Enhanced Superfin node. These new Xeon server chips are compatible with the LGA4677 (Socket E) socket and use the company’s Golden Cove cores.
At the same time, Intel’s Sapphire Rapids chips support PCIe 5.0 and DDR5. Each processor also has up to four Ultra Path Interconnect (UPI) 2.0 links to connect to other processors on multi-socket motherboards. The chipmaker’s latest processor is said to have 48 cores, 96 threads, and 90MB of L3 cache. The sample technical chip reviewed by YuuKi-AnS has a 2.3GHz base clock, a 3.3GHz boost clock, and 270W TDP.
Sapphire Rapids Achievements
YuuKi-AnS tested Intel’s Sapphire Rapids chip, the Xeon Platinum 8380 chip, and an AMD EPYC 773X chip in dual-socket configurations.
While the Sapphire Rapids and Xeon Platinum 8380 systems have 96 and 80 cores respectively, the system with an AMD EPYC 773X processor beats both on paper with 128 cores. Theoretically, AMD’s processor will excel at handling multi-threaded workloads compared to both processors from Intel.
As for YuuKi-AnS’s test results, the Sapphire Rapids chip scored 1,033 in the Cinebench R23 single-core benchmark and 67,932 in the Cinebench’s multi-core benchmark. Meanwhile, the EPYC 773X system scored 712 and 82,464 in the same benchmark, while the Xeon Platinum 8380 system scored 950 and 66,242. It’s worth noting that since the Sapphire Rapids processors tested were technical examples, the clock speeds are not definitive.
We’ll likely learn more about Sapphire Rapids’ real-world performance later this year, as Intel has said it plans to launch its next-generation Xeon scalable processor in the third quarter.
