AMD Ryzen Threadripper PRO 5975WX vs Intel Xeon w7-2595X Comparison

The Verdict

The AMD Ryzen Threadripper PRO 5975WX is the dominant multi-threaded workstation processor in this comparison, winning 14 of 17 head-to-head benchmark matchups. Its 32 cores and 64 threads create a substantial throughput advantage over the Intel Xeon w7-2595X, which fields 26 cores and 52 threads. In Cinebench tests, the AMD part leads by a consistent 16.7% across both single-core and multi-core workloads, a uniformity that points to a well-balanced architectural edge rather than a workload-specific quirk. The Threadripper PRO also delivers massive wins in integer math, data encryption, and prime number finding, where it outperforms the Xeon by 37.8%, 61.6%, and 69.1%, respectively.

The Intel Xeon w7-2595X, however, claims the single-threaded crown in Passmark with a score of 3723 versus 3323, a 10.7% advantage. It also edges out the AMD part in floating-point math, scoring 202906 against 202363, a marginal 0.3% difference. This makes the Xeon the better choice for lightly threaded workloads that rely on raw per-core speed, such as legacy simulation codes or certain types of single-threaded analysis. The AMD chip counters with a higher boost clock of 4.50 GHz, but the Xeon's boost clock reaches 4.80 GHz, which explains the Passmark single-thread result.

The data indicates the Threadripper PRO 5975WX should be selected for render farms, scientific computing, and any environment where core count and memory bandwidth (204.8 GB/s versus 153.6 GB/s) translate directly into reduced wall-clock time. The Xeon w7-2595X suits users who need Intel's platform features, such as PCIe Gen 5 with 64 lanes, and who prioritize per-core responsiveness over absolute multi-core throughput. The AMD part also carries a higher launch MSRP of $3299, while the Intel part lists at $2039, though the performance delta in multi-core tasks often justifies the premium for production workloads.

Architecture Differences

The AMD Ryzen Threadripper PRO 5975WX is built on the Zen 3 architecture, codenamed Chagall PRO, using a 7 nm process from TSMC. It deploys four chiplets, each with a die size of 81 mm², totaling 16,600 million transistors. The Intel Xeon w7-2595X uses the Sapphire Rapids codename on Intel's 10 nm process, with no transistor count or die size listed in the database. The AMD part features 64 KB of L1 cache per core and 512 KB of L2 per core, while the Intel part has 80 KB of L1 and 2 MB of L2 per core. The L3 cache is a major differentiator: the Threadripper PRO offers 128 MB, while the Xeon provides 48.75 MB, a 2.6x difference that heavily favors the AMD chip in cache-sensitive workloads.

Memory architecture diverges sharply. The AMD processor supports DDR4 with an eight-channel memory bus, delivering 204.8 GB/s of bandwidth. The Intel processor supports DDR5 with a quad-channel bus, delivering 153.6 GB/s. Despite the newer DDR5 standard, the Intel part has fewer channels, resulting in lower peak bandwidth. Both support ECC memory, which is expected for workstation platforms. The PCIe interface also differs: AMD provides Gen 4 with 128 lanes (CPU only), while Intel provides Gen 5 with 64 lanes (CPU only). The Intel part offers newer interconnect speed but half the lane count.

The AMD part has a base clock of 3.60 GHz and a boost clock of 4.50 GHz, with a TDP of 280 W. The Intel part runs at a lower base clock of 2.80 GHz but boosts higher to 4.80 GHz, with a TDP of 250 W. The Intel processor has an unlocked multiplier, enabling overclocking, while the AMD part is locked. The AMD socket is WRX8, the Intel socket is 4677. The AMD part was released on March 7, 2022, while the Intel part arrived later on August 23, 2024. Neither part includes integrated graphics on the AMD side, while the Intel side lists N/A for integrated graphics.

Head-to-Head Benchmarks

The Cinebench suite shows a perfectly uniform 16.7% advantage for the AMD Ryzen Threadripper PRO 5975WX across all three versions (R15, R20, R23) and both single-core and multi-core tests. In R23 multi-core, the AMD scores 64021 against 54863, a difference of 9158 points. In R23 single-core, the AMD scores 9038 against 7745. This consistency suggests the Zen 3 architecture delivers a per-clock IPC advantage that scales evenly, regardless of thread count.

The Passmark suite tells a more nuanced story. The AMD part wins data compression with 1293784 versus 983046, a 31.6% margin. Data encryption shows a 61.6% gap (80453 versus 49782), likely reflecting the AMD part's larger L3 cache and higher thread count. Extended instructions see a modest 6.7% win for AMD (82850 versus 77613). Prime number finding is the largest AMD victory at 69.1% (438 versus 259), a workload that scales almost linearly with core count. Integer math shows a 37.8% advantage (360156 versus 261384), while multithread scoring gives AMD a 16.5% edge (75319 versus 64628). Physics tests favor AMD by 58% (4360 versus 2759), and random string sorting goes to AMD by 20.8% (123527 versus 102230).

The Intel Xeon w7-2595X wins two Passmark tests. Floating-point math is essentially a tie, with Intel at 202906 and AMD at 202363, a 0.3% difference that falls within measurement noise. Single-thread performance, however, is a clear Intel win: 3723 versus 3323, a 10.7% margin. This aligns with the Intel part's higher boost clock of 4.80 GHz versus 4.50 GHz. The single-thread result appears twice in the data (as "passmark_single_thread" and "passmark_singlethread"), both showing the same scores, confirming the measurement.

The overall average benchmark score for the AMD part is 124171, placing it at the 97th percentile of all CPUs. The Intel part has an average score of 108663, also at the 97th percentile. This means both parts sit in the top tier of the database, but the AMD part holds a 14.3% higher average score. The nearest rivals for the AMD part include the AMD EPYC 7642 (avg score 124006, delta 0.1%) and the AMD EPYC 9384X (avg score 120427, delta 3.1%), showing it competes directly with server-class silicon. The Intel part's nearest rivals include the AMD Ryzen 9 PRO 9955 (avg score 110612, delta -1.8%) and the Intel Xeon w7-3555 (avg score 106192, delta 2.3%), indicating it sits in a slightly lower performance tier.
