CPU Comparison

The AMD Ryzen Threadripper 1950X and Intel Xeon W-2191B are both high-core-count processors from the 2017 era, yet they target different segments: the Threadripper is a desktop part, while the Xeon is a workstation/server processor. The benchmark data shows a clear overall winner in the Intel Xeon W-2191B, which takes 7 of the 8 head-to-head tests, but the single-core result and architectural differences create a nuanced picture. The Xeon W-2191B holds a decisive lead in multi-threaded workloads, particularly in Geekbench, while the Threadripper 1950X offers a marginal, but notable, win in single-core performance.

Where Each One Wins

The Intel Xeon W-2191B dominates the multi-core arena across every Cinebench iteration and Geekbench. In Cinebench R15, R20, and R23 multi-core tests, the Xeon leads by a consistent margin of 1.9% in each case, scoring 2407, 10032, and 23887 respectively, versus the Threadripper’s 2362, 9844, and 23440. The most striking difference appears in Geekbench multi-core, where the Xeon W-2191B scores 9614 against the Threadripper’s 7989, a substantial 16.9% advantage. This indicates that the Xeon’s additional 2 cores and 4 threads (18 cores/36 threads vs 16 cores/32 threads) translate into significant gains in heavily parallelized applications, likely due to better scaling in workloads that leverage many threads.

The AMD Ryzen Threadripper 1950X’s only victory comes in Geekbench single-core, where it scores 1183 versus the Xeon’s 1182, a razor-thin 0.1% margin. While this is technically a win, the delta is negligible and within measurement noise. However, the Threadripper also shows competitive single-core results in Cinebench, trailing by only 1.8% in R15 (333 vs 339) and 1.9% in R20 and R23 (1389 vs 1416, and 3309 vs 3372 respectively). For users prioritizing single-threaded responsiveness, the Threadripper’s higher base clock of 3.40 GHz (versus 2.30 GHz on the Xeon) likely contributes to its slight edge, despite the Xeon’s higher boost clock of 4.30 GHz.

The Xeon W-2191B also wins on efficiency metrics. Its thermal design power (TDP) is 140 watts, compared to the Threadripper’s 180 watts, meaning the Xeon delivers higher multi-core performance while consuming less power. This makes the Xeon the clear choice for sustained all-core workloads where thermals and power draw are a concern. The Threadripper, by contrast, is a desktop part with an unlocked multiplier, suggesting it is designed for enthusiasts who may overclock to close the gap, though the data shows it cannot match the Xeon’s raw multi-core output at stock settings.

The Verdict

Based strictly on benchmark results, the Intel Xeon W-2191B is the superior processor for multi-threaded workloads. It wins 7 out of 8 head-to-head comparisons and holds a commanding 16.9% lead in Geekbench multi-core, which is the largest performance gap in the entire dataset. Its consistent 1.9% advantage across all Cinebench multi-core tests reinforces this dominance. The Xeon also achieves this with a lower TDP (140W vs 180W), making it more power-efficient for server or workstation environments where sustained load is common. With ECC memory support and 48 PCIe Gen 3 lanes, the Xeon W-2191B is architecturally positioned for reliability and expandability in professional settings.

The AMD Ryzen Threadripper 1950X, however, is not without merit. Its single-core Geekbench win, while marginal, suggests it has slightly better per-thread performance in certain scenarios. The unlocked multiplier offers overclocking potential that the locked Xeon lacks, allowing users to potentially boost performance beyond stock figures. As a desktop part with a launch MSRP of $999, the Threadripper targets a different audience, enthusiasts who want high core counts for content creation or gaming, but who value flexibility and the ability to tune their hardware. For users who prioritize single-threaded tasks or plan to overclock, the Threadripper is the better choice; for those who need maximum multi-core throughput out of the box, the Xeon W-2191B is the definitive pick.

Head-to-Head Benchmarks

The most lopsided result is in Geekbench multi-core, where the Intel Xeon W-2191B scores 9614 versus the Threadripper’s 7989. This 16.9% delta is the largest in the comparison and highlights the Xeon’s advantage in applications that scale well with core count and memory bandwidth. The Cinebench multi-core tests show a tighter race, with the Xeon winning R15 (2407 vs 2362), R20 (10032 vs 9844), and R23 (23887 vs 23440) by 1.9% each. This consistency suggests that the Xeon’s extra cores provide a steady, predictable benefit in rendering workloads, though not an overwhelming one.

Single-core results are nearly identical across the board. In Cinebench R15, the Xeon wins 339 to 333 (1.8% delta), and in R20 and R23, it wins 1416 to 1389 and 3372 to 3309, respectively, each by 1.9%. The only AMD victory is in Geekbench single-core, where the Threadripper edges out the Xeon 1183 to 1182, a 0.1% delta that is effectively a tie. This pattern indicates that the Threadripper’s higher base clock (3.40 GHz) helps it stay competitive in lightly threaded tasks, but the Xeon’s higher boost clock (4.30 GHz) allows it to pull ahead in most single-threaded benchmarks. The overall average benchmark score reinforces the Xeon’s standing: it averages 6531 versus the Threadripper’s 6231, placing the Xeon in the same performance tier as the Intel Core i9-7960X (delta 0%) and the AMD Ryzen Threadripper 1950X (delta 0.7% versus the EPYC 7272).

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen Threadripper 1950X uses the Zen architecture (codename "Zen") on a 14 nm process from GlobalFoundries, with a die size of 2x 213 mm² and 9,600 million transistors. It features 16 cores and 32 threads with a base clock of 3.40 GHz and a boost clock of 4.00 GHz. The cache hierarchy includes 96 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3 cache. It supports DDR4 memory in a quad-channel configuration with 85.3 GB/s bandwidth, but does not support ECC memory. The socket is AMD Socket SP3r2, and the part number is YD195XA8UGAAE.

The Intel Xeon W-2191B uses the Skylake architecture (codename "Skylake-W") on a 14 nm process from Intel, with a single die size of 484 mm². It has 18 cores and 36 threads with a base clock of 2.30 GHz and a boost clock of 4.30 GHz. Its cache layout is different: 64 KB of L1 per core, 1 MB of L2 per core, and 24.75 MB of shared L3 cache. It also supports DDR4 memory in a quad-channel configuration with the same 85.3 GB/s bandwidth, but it does support ECC memory. The Xeon uses Intel Socket 2066 and offers 48 PCIe Gen 3 lanes (CPU only). It is classified as a server/workstation part with end-of-life production status, while the Threadripper is an active desktop part. The Xeon’s memory bandwidth is identical to the Threadripper’s, but its larger core count and shared L3 cache design appear to benefit multi-threaded scaling. The Threadripper’s higher base clock and unlocked multiplier make it more appealing for desktop enthusiasts, whereas the Xeon’s ECC support and PCIe lane count target professional workstations.
