AMD Ryzen Threadripper PRO 5975WX vs Intel Xeon 6710E Comparison

The Intel Xeon 6710E and AMD Ryzen Threadripper PRO 5975WX are both heavy-duty workstation processors targeting the same market segment, yet they approach the workload from entirely different design philosophies. The Xeon 6710E packs 64 efficiency-focused cores into a single Sierra Forest die, while the Threadripper PRO 5975WX deploys 32 high-frequency Zen 3 cores across four chiplets. Benchmark data shows a clear split: the AMD part dominates most compute-heavy tests, but the Intel processor carves out wins in specific workloads where its core count and architecture shine.

Head-to-Head Benchmarks

The most striking result in this comparison is the single-thread performance gap. The Threadripper PRO 5975WX scores 3,323 in PassMark single-thread, which is 42.5% higher than the Xeon 6710E’s 1,910. This gap repeats across Cinebench tests: in R23 single-core, AMD leads 9,038 to 7,413, a delta of -18% for Intel. The same -18% delta appears in R15 single-core (910 vs 747) and R20 single-core (3,795 vs 3,113). The Threadripper’s 4.50 GHz boost clock versus 3.20 GHz on the Xeon is the obvious driver, but the architectural advantage of Zen 3’s larger per-core resources also plays a role.

Multi-core performance tells a similar story, though with narrower margins. In Cinebench R23 multi-core, the Threadripper PRO 5975WX scores 64,021 against 52,508 for the Xeon 6710E—an 18% advantage despite having half the cores. The same -18% delta appears in R15 multi-core (6,453 vs 5,292), R20 multi-core (26,888 vs 22,053), and PassMark multithread (75,319 vs 61,775). The Threadripper also wins PassMark integer math by 15.9% (360,156 vs 302,954) and extended instructions by 28% (82,850 vs 59,625). Data compression is closer: AMD leads 1,293,784 to 1,230,786, a 4.9% margin.

However, the Xeon 6710E has its own victories. Its most decisive win is random string sorting, where it scores 151,491 against 123,527—a 22.6% lead for Intel. Floating-point math also favors the Xeon: 219,926 vs 202,363, an 8.7% advantage. Physics tests show Intel ahead by 14.7% (5,000 vs 4,360), and find prime numbers yields a narrow 3% win (451 vs 438). Data encryption is close but favors Intel, 81,850 vs 80,453, a 1.7% margin.

Looking at the overall head-to-head tally, AMD wins 12 of 17 benchmarks, while Intel takes 5. The average benchmark score reflects this: the Xeon 6710E averages 129,930, which is 4.6% higher than the Threadripper PRO 5975WX’s 124,171. That discrepancy comes from the Xeon’s strong showings in specific PassMark sub-tests and the weighting of the average score. Both chips sit at the 97th percentile among all CPUs, but the distribution of wins matters: the Threadripper dominates mainstream rendering and integer workloads, while the Xeon excels in memory-heavy and floating-point tasks.

The Verdict

The data points to two distinct buyer profiles. If the workload involves Cinebench-style rendering, integer math, or single-threaded responsiveness, the AMD Ryzen Threadripper PRO 5975WX is the clear choice. It leads by 18% in every Cinebench multi-core test and by 42.5% in single-thread performance. For professionals running 3D renderers, code compilation, or simulation software that scales with per-core speed, this chip’s 3.60 GHz base and 4.50 GHz boost clocks deliver tangible results.

The Intel Xeon 6710E makes sense for workloads that exploit its 64 cores and memory bandwidth. Its 358.4 GB/s eight-channel DDR5 bandwidth dwarfs the Threadripper’s 204.8 GB/s DDR4, which explains its 22.6% lead in random string sorting and 8.7% edge in floating-point math. Server-style workloads like data encryption (1.7% lead) and prime number finding (3% lead) also favor Intel. If the application is memory-latency sensitive or relies on FPU throughput, the Xeon’s 96 MB shared L3 cache and 5 nm process node provide the edge.

The average benchmark scores complicate the verdict. The Xeon 6710E’s 129,930 average is 4.6% higher than the Threadripper’s 124,171, yet the Threadripper wins the majority of individual tests. This suggests the Xeon’s wins are concentrated in tests that carry more weight in the average, such as floating-point and data compression. For a mixed workload environment, the Intel part may edge ahead overall. For pure compute throughput, AMD wins.

Architecture Differences

The two processors come from fundamentally different design lineages. The Intel Xeon 6710E uses the Sierra Forest architecture on a 5 nm Intel node, featuring 64 cores with 64 threads—no hyperthreading. Its L1 cache is 96 KB per core, L2 is 4 MB per module, and L3 is 96 MB shared. The die size is 578 mm², indicating a monolithic design. This is a server-first architecture optimized for density and power efficiency per core, not per-core speed.

The AMD Ryzen Threadripper PRO 5975WX uses Zen 3 architecture on TSMC’s 7 nm node, packaged as four 81 mm² chiplets totaling 16,600 million transistors. Each core has 64 KB L1 and 512 KB L2, with a shared 128 MB L3. The chiplet design allows higher clock speeds but adds inter-chiplet latency. Both CPUs support ECC memory and target the server/workstation segment, but their memory ecosystems diverge: Intel uses DDR5 with eight-channel support, while AMD uses DDR4 with eight-channel support.

The PCIe configurations also differ. The Xeon 6710E offers PCIe Gen 5 with 88 lanes (CPU only), while the Threadripper PRO 5975WX provides PCIe Gen 4 with 128 lanes. This affects expansion capability: AMD offers more lanes but older generation, while Intel offers fewer lanes but newer standard. Neither has integrated graphics, and both lack unlocked multipliers.

The core count difference is stark: 64 vs 32, yet both run 64 threads. The Xeon achieves this with single-thread-per-core efficiency cores, while AMD uses simultaneous multithreading on 32 faster cores. The clock speed gap is substantial—the Threadripper boosts 40% higher. Memory bandwidth heavily favors Intel (358.4 vs 204.8 GB/s), while the Threadripper has 33% more L3 cache (128 MB vs 96 MB). The Xeon is newer by over two years, which is reflected in its 5 nm node versus 7 nm.
