Intel Xeon Platinum 8260 vs Intel Xeon W-2195 Comparison

The Intel Xeon Platinum 8260 and Intel Xeon W-2195 are both high-core-count Intel server/workstation processors, but the benchmark data reveals a consistent, albeit narrow, edge for the Platinum 8260. Across every Cinebench test — R15, R20, and R23, in both single-core and multi-core — the Platinum 8260 wins, with deltas of 1.4% to 1.5%. The W-2195, an older Skylake-W part, trails in every metric despite its higher boost clock. The data suggests that the Platinum 8260 is the better performer for raw compute workloads, while the W-2195 offers a different platform trade-off with its older socket and quad-channel memory bus.

The Verdict

From the benchmark results, the Intel Xeon Platinum 8260 is the clear performance winner, taking all six head-to-head Cinebench comparisons. The largest advantage is 1.5% in Cinebench R15 multi-core (2436 vs 2401) and single-core (343 vs 338) and R20 single-core (1433 vs 1412). The smallest margin is 1.4% in R20 multi-core (10152 vs 10007) and R23 multi-core (24173 vs 23828). This means that for users whose primary concern is maximizing Cinebench scores, the Platinum 8260 is the pick. The data shows no workload where the W-2195 pulls ahead.

However, the W-2195 is not without its own merits. It has a higher boost clock of 4.30 GHz compared to the Platinum 8260's 3.90 GHz, and it features a quad-channel memory bus with 85.3 GB/s of bandwidth, whereas the Platinum 8260's memory bus details are not listed. The W-2195 also has a lower TDP of 140 watts versus 165 watts for the Platinum 8260, and it is marked as end-of-life, while the Platinum 8260's production status is not specified. The W-2195's launch MSRP is $2553, a figure that should be noted once for context.

Given these facts, the verdict is straightforward: choose the Platinum 8260 for superior benchmark performance across the board. Choose the W-2195 if the specific platform features matter more — namely the higher boost clock, lower TDP, and the documented quad-channel memory configuration — or if the older Intel Socket 2066 platform is a requirement. The data does not support choosing the W-2195 for any Cinebench-based performance reason.

Architecture Differences

The two processors come from different Intel microarchitectures. The Platinum 8260 is based on Cascade Lake, specifically the Cascade Lake-SP generation, while the W-2195 is based on the older Skylake architecture, known as Skylake-W. This architectural gap is significant because it means the Platinum 8260 is a newer design. Both are built on the same 14 nm process node, but the Platinum 8260 has a higher transistor count of 8,000 million, whereas the W-2195's transistor count is not listed in the data. The W-2195 does have a documented die size of 484 mm².

The core counts differ substantially. The Platinum 8260 packs 24 cores and 48 threads, while the W-2195 offers 18 cores and 36 threads. This 6-core advantage for the Platinum 8260 is a key architectural differentiator. The cache hierarchy reveals a similar story: both have 64 KB of L1 and 1 MB of L2 per core, but the L3 cache is larger on the Platinum 8260 at 35.75 MB shared, compared to 24.75 MB on the W-2195. That extra cache and additional cores likely contribute to the Platinum 8260's benchmark edge.

The sockets and platforms are entirely different. The Platinum 8260 uses Intel Socket 3647, a server-oriented platform, while the W-2195 uses Intel Socket 2066. The W-2195's platform explicitly supports PCIe Gen 3 with 48 lanes (CPU only) and a quad-channel memory bus with a documented bandwidth of 85.3 GB/s. The Platinum 8260's PCIe lanes and memory bandwidth are not listed, leaving a gap in direct comparison. The W-2195 is also marked as end-of-life in production status, while the Platinum 8260's status is not specified. The release dates differ too: the Platinum 8260 launched on 2018-12-10, while the W-2195 launched earlier on 2017-08-28.

Specification Differences

The specification table shows where the two diverge. The most obvious difference is core and thread count: 24 cores/48 threads for the Platinum 8260 versus 18 cores/36 threads for the W-2195. Base clocks are close, with the Platinum 8260 at 2.40 GHz and the W-2195 at 2.30 GHz, a 0.10 GHz gap. Boost clocks, however, favor the W-2195: 4.30 GHz versus 3.90 GHz for the Platinum 8260. The TDP also differs, with the Platinum 8260 rated at 165 watts and the W-2195 at a lower 140 watts.

The sockets are different, as noted: Intel Socket 3647 for the Platinum 8260 and Intel Socket 2066 for the W-2195. The memory support is DDR4 for both, but the W-2195 specifies a quad-channel bus and 85.3 GB/s bandwidth, while the Platinum 8260 lists no memory bus or bandwidth details. The W-2195 also has an explicit PCIe configuration of Gen 3 with 48 lanes (CPU only), which the Platinum 8260 does not list. The W-2195 has a launch MSRP of $2553, while the Platinum 8260 has no launch MSRP provided. Finally, the part numbers differ: SRF9HCD8069504201101 for the Platinum 8260 and SR3RX for the W-2195.

Head-to-Head Benchmarks

The head-to-head data is unambiguous: the Platinum 8260 wins every single test. In Cinebench R15 multi-core, the Platinum 8260 scores 2436 against the W-2195's 2401, a 1.5% margin. The single-core R15 test shows a similar 1.5% lead, with scores of 343 and 338. Moving to Cinebench R20, the multi-core scores are 10152 for the Platinum 8260 and 10007 for the W-2195, a 1.4% delta. The R20 single-core test again shows a 1.5% difference, with 1433 versus 1412.

In the newest Cinebench R23 tests, the pattern holds. The multi-core score for the Platinum 8260 is 24173, compared to 23828 for the W-2195, a 1.4% difference. The single-core R23 scores are 3412 and 3363, respectively, also a 1.5% delta. The fact that the deltas are so consistent — hovering between 1.4% and 1.5% across all tests — suggests a systematic advantage for the Platinum 8260, likely stemming from its extra cores and larger L3 cache. The W-2195's higher boost clock does not translate into any single-core win, as the Platinum 8260 still edges it out in every single-core test.

When looking at the broader benchmark context, the Platinum 8260's average benchmark score of 6992 is higher than the W-2195's 6892. The Platinum 8260's nearest rivals include the Intel Core i9-7980XE (avg score 7018, 0.4% higher) and the Intel Core i9-9960X (avg score 6938, 0.8% lower). The W-2195's nearest rivals are the Intel Core i5-3470 (avg score 6906, 0.2% higher) and the AMD Ryzen 3 3200G (avg score 6931, 0.6% higher). This places both CPUs in the same 63rd percentile of all CPUs, but the Platinum 8260 sits closer to stronger rivals like the i9-7980XE.

Where Each One Wins

The Platinum 8260 wins in all measured performance categories. In multi-core workloads, its 24 cores and 48 threads give it a consistent edge over the W-2195's 18 cores and 36 threads. The Cinebench R23 multi-core score of 24173 versus 23828 is the largest absolute gap, representing a 345-point difference. This makes the Platinum 8260 the better choice for heavily threaded tasks like 3D rendering, video encoding, and scientific simulations, based on the Cinebench data.

The Platinum 8260 also wins in single-core performance, despite the W-2195's higher boost clock. The R23 single-core scores of 3412 versus 3363 show a 49-point advantage. This suggests that the Platinum 8260's architecture is more efficient per clock, even if it cannot reach the same peak boost frequency. For workloads that are lightly threaded, such as everyday productivity or certain legacy applications, the Platinum 8260 still holds the edge.

The W-2195 does not win any benchmark, but it has platform advantages that are not captured in Cinebench scores. Its lower TDP of 140 watts versus 165 watts means it draws less power under load, which could be relevant for dense server deployments. The quad-channel memory bus with 85.3 GB/s of bandwidth is a specific feature that the Platinum 8260's data does not list, potentially benefiting memory-bandwidth-sensitive applications. The W-2195 also has a documented PCIe Gen 3 configuration with 48 lanes, which may be a deciding factor for users with specific expansion needs. For users on the Intel Socket 2066 platform, the W-2195 is the only choice between the two, as the Platinum 8260 requires Socket 3647. The W-2195's end-of-life status, however, means it is no longer in active production, while the Platinum 8260's production status is not listed, leaving future availability an open question.
