Intel Xeon W7-3455 Sapphire Rapids Workstation 24-Core CPU Tested, Slower Than 24-Core Threadripper 5965WX

The specific chip relies entirely on its Golden Cove cores which total 24 along with 48 threads. The CPU should have a base clock of 2.5 GHz and a boost clock of up to 4.8 GHz. The CPU will also incorporate 67.5 MB of L3 cache and an 8-channel IMC. TDP is expected to be rated at 270W.

Those are some decent specifications and the chip was tested within the V-Ray 5 benchmark. The Intel Xeon W7-3455 "Sapphire Rapids" workstation CPU scored 26,175 points. The score looks a bit underwhelming compared to AMD's Threadripper PRO 5965WX which has the same 24 cores and 48 threads (Zen 3 architecture) but is able to score 30,700 points or 17% higher performance. This makes me think that the Xeon chip might be an early sample considering it even loses to the Core i9-13900K which is able to score 28,907 points.


Intel's Sapphire Rapids Xeon Workstation CPUs are headed for an official unveiling on the 15th of February and we have more benchmark leaks.
