Intel Xeon W9-3575X and W7-2595X CPUs Benchmarked: First Look at Sapphire Rapids Refresh

The first benchmarks of Intel’s Sapphire Rapids Refresh CPUs, the 44-core Xeon W9-3575X and the 26-core Xeon W7-2595X, have been unveiled, showcasing significant advancements in performance and efficiency.

Intel Sapphire Rapids Refresh: Xeon W9-3575X and Xeon W7-2595X

Intel’s Sapphire Rapids Refresh CPUs are set to launch on the W790 platforms, bringing more cores, increased cache, and faster clock speeds. These processors are designed for workstation platforms but also support various overclocking capabilities on enthusiast motherboards, aiming to set new performance records.

Detailed Specifications and Benchmarks

The Xeon W9-3575X is a powerhouse with 44 cores and 88 threads, featuring a base clock of 2.2 GHz and a boost clock of 4.6 GHz. It boasts 97.50 MB of L3 cache and 88 MB of L2 cache, with a TDP of 340W. This CPU supports 8-channel memory, tested with eight 32 GB DDR5-7000 modules on the ASUS PRO WS W790E-SAGE SE motherboard.

On the other hand, the Xeon W7-2595X offers 26 cores and 52 threads, with a base clock of 2.8 GHz and a boost clock of 4.8 GHz. It includes 48.75 MB of L3 cache and 52 MB of L2 cache, with a TDP of 250W. This CPU was tested with quad-channel memory, using four 16 GB DDR5-6000 sticks on the ASUS PRO WS W790-ACE motherboard.

Performance Comparison

Compared to their predecessors, the Xeon W9-3575X provides 8 additional cores, 16 more threads, and 15 MB more L3 cache, albeit with slightly lower clock speeds due to its engineering sample nature. The Xeon W7-2595X offers 2 additional cores, 2 more threads, and a 3.75 MB increase in cache capacity.

Xeon W9-3575X vs W9-3475X: +8 Cores / +16 Threads / +15 MB L3 Cache / +40W TDP
Xeon W7-3595X vs W7-3495X: +2 Cores / +4 Threads / +3.75 MB L3 Cache / +25W TDP

Conclusion

The Intel Sapphire Rapids Refresh CPUs, Xeon W9-3575X and W7-2595X, offer a modest performance uplift over their predecessors, thanks to the additional cores, cache, and TDP. These improvements, while not revolutionary, provide decent gains at similar or lower price points. The compatibility with existing platforms ensures that workstation users and enthusiasts can upgrade without needing new hardware.

Despite these advancements, AMD’s Threadripper series is expected to maintain its dominance in the workstation and HEDT segments.

Stay tuned for more updates as we approach the official launch of Intel’s Sapphire Rapids Refresh CPUs.
