AMD EPYC 9745 vs AMD Ryzen Threadripper PRO 9995WX Comparison

The AMD EPYC 9745 and AMD Ryzen Threadripper PRO 9995WX are both flagship AMD processors aimed at the highest tiers of server and workstation performance. The benchmark data reveals a clear split: the EPYC 9745 excels in specific data-heavy throughput tasks, while the Threadripper PRO dominates in raw multi-threaded compute and single-core responsiveness. The EPYC 9745 scores an average of 425,973 across all benchmarks, landing 4.8% above the Threadripper PRO 9995WX’s average of 406,395. Both chips sit at the 100th percentile among all CPUs tested. The EPYC 9745 wins 6 of the 17 head-to-head tests, while the Threadripper PRO takes 11.

Head-to-Head Benchmarks

The most striking pattern in the data is the Threadripper PRO’s sweeping victory across the entire Cinebench suite. In Cinebench R23 multi-core, the Threadripper PRO scores 148,601 against the EPYC’s 111,093, a 25.2% lead. This gap is remarkably consistent: the Threadripper PRO also leads by 25.2% in Cinebench R15 multi-core (14,978 vs 11,198) and by 25.2% in Cinebench R20 multi-core (62,412 vs 46,659). Single-core results follow the same shape, with the Threadripper PRO ahead by 25.3% in R15 (2,114 vs 1,580) and R20 (8,811 vs 6,586), and by 25.2% in R23 (20,979 vs 15,683). This uniformity suggests a consistent per-core advantage for the Threadripper PRO across all Cinebench workloads, not a workload-specific quirk.

The Passmark suite tells a different story. The EPYC 9745 wins the data compression test with 3,929,890 points versus 3,627,619 for the Threadripper PRO, a 8.3% margin. Data encryption also favors the EPYC, which scores 229,447 against 215,680, a 6.4% edge. The largest EPYC win comes in extended instructions, where it posts 280,477 versus 247,436, a 13.4% advantage. Floating point math also goes to the EPYC (761,219 vs 707,600, or 7.6% ahead), and random string sorting follows with a 9.9% win (468,975 vs 426,857). The integer math test is nearly a tie: the EPYC scores 1,224,315 against the Threadripper’s 1,220,090, a razor-thin 0.3% margin.

The Threadripper PRO’s Passmark wins are equally decisive in its favor. The single-thread test shows a 38.5% gap, with the Threadripper scoring 4,565 against the EPYC’s 2,806. The find prime numbers test is another strong Threadripper win: 1,573 versus 979, a 37.8% lead. The multithread test goes to the Threadripper by 25.2% (174,825 vs 130,698), mirroring the Cinebench multi-core delta. Physics also favors the Threadripper, scoring 20,011 versus 17,122, a 14.4% margin. Notably, the Threadripper PRO’s wins are often larger than the EPYC’s: the 38.5% single-thread and 37.8% prime-number margins dwarf the EPYC’s best win of 13.4% in extended instructions.

Where Each One Wins

The EPYC 9745’s wins cluster around workloads that stress memory bandwidth and data manipulation. Data compression, encryption, extended instructions, floating point math, and random string sorting all fall to the EPYC. These tasks often benefit from the EPYC’s twelve-channel memory bus, which provides 576.0 GB/s of bandwidth compared to the Threadripper’s eight-channel 409.6 GB/s. The EPYC also has 128 cores versus the Threadripper’s 96, which may help in highly parallel data-processing pipelines that are not limited by per-core clock speed.

The Threadripper PRO 9995WX wins everywhere else. Its Cinebench sweep indicates a substantial per-core performance advantage, likely stemming from its 5.40 GHz boost clock versus the EPYC’s 3.70 GHz. The single-thread and find-prime-numbers results reinforce this: these are latency-sensitive tasks where higher clocks matter more than core count. The multithread Passmark score and physics test also favor the Threadripper, suggesting that even in parallel workloads, the higher clock speed and per-core efficiency can overcome a 32-core deficit. The Threadripper’s 384 MB of shared L3 cache, compared to the EPYC’s 256 MB, may also play a role in workloads with large working sets that fit in cache.

The Verdict

The data points to a simple split: choose the AMD EPYC 9745 for server-style data throughput, and the AMD Ryzen Threadripper PRO 9995WX for workstation-style compute. The EPYC 9745 leads in data compression, encryption, extended instructions, floating point math, and random string sorting, all by margins from 6.4% to 13.4%. These are the workloads where the EPYC’s 128 cores and twelve-channel memory bandwidth pay off. The Threadripper PRO 9995WX, however, wins 11 of the 17 tests, including all Cinebench benchmarks and the crucial single-thread test. Its 25.2% lead in multi-core Cinebench and 38.5% lead in single-thread Passmark are far larger than any EPYC advantage. For users running rendering, simulation, or general compute that scales with per-core speed, the Threadripper is the stronger choice. The EPYC is the pick for data-center tasks like compression and encryption, where its bandwidth and core count matter most. The overall average score favors the EPYC by 4.8%, but that figure is heavily influenced by the EPYC’s large wins in data-heavy tests; the Threadripper’s consistent wins across Cinebench and single-thread workloads argue for it in most desktop or workstation scenarios.
