AMD EPYC 7F52 vs AMD Ryzen Threadripper PRO 5945WX Comparison

Head-to-Head Benchmarks

The recorded data presents a remarkably consistent picture across all six Cinebench comparisons: the AMD EPYC 7F52 wins every single test, and it does so by an identical margin of 2.7% in each case. This uniformity is unusual in processor benchmarking, where workload characteristics typically produce varying deltas across different renderers and scene complexities. Here, the EPYC 7F52's advantage holds steady whether the test stresses all cores or just one.

In Cinebench R15 multicore, the EPYC 7F52 scores 3540 against the Threadripper PRO 5945WX's 3447, a 2.7% edge that puts roughly 93 points between them. The single-core R15 result follows the same pattern: 499 versus 486, again a 2.7% lead. Moving to Cinebench R20, the multicore gap widens in absolute terms, with the EPYC reaching 14751 while the Threadripper manages 14365, though the percentage delta remains locked at 2.7%. The single-core R20 scores of 2082 and 2027 show the same relative difference.

Cinebench R23, the most demanding of the trio, repeats the script. The EPYC 7F52 posts 35123 multicore, the Threadripper 34204, and the single-core results are 4958 and 4828 respectively. Every one of these six head-to-head matchups favors the EPYC 7F52, and the victory margin never strays from 2.7%. The win count stands at six for the EPYC 7F52 and zero for the Threadripper PRO 5945WX.

While the EPYC's sweep is clear, the absolute differences are modest. A 2.7% gap in Cinebench R23 multicore translates to roughly 900 points, which is meaningful for long render jobs but not a generational leap. The Threadripper's higher boost clock of 4.50 GHz against the EPYC's 3.90 GHz does not translate into a single-core victory, suggesting that architectural efficiency plays a larger role than raw frequency in these workloads.

Architecture Differences

The two processors come from different AMD generations and are built on different Zen microarchitectures. The EPYC 7F52 uses Zen 2, codenamed Rome, while the Threadripper PRO 5945WX uses Zen 3, codenamed Chagall PRO. Both are manufactured on TSMC's 7 nm process, but the similarities largely end there.

The EPYC 7F52 packs 16 cores and 32 threads, while the Threadripper PRO 5945WX has 12 cores and 24 threads. That is four fewer cores and eight fewer threads on the Threadripper, yet the benchmark data shows only a 2.7% performance deficit in the EPYC's favor. This indicates that Zen 3's per-core improvements are substantial, allowing the Threadripper to nearly match a processor with 33% more cores in multicore workloads.

Transistor counts differ dramatically. The EPYC 7F52 contains 3,800 million transistors on a 74 mm² die, while the Threadripper PRO 5945WX packs 16,600 million transistors across 4x 81 mm² dies. The Threadripper's multi-chip design with four separate dies explains the higher transistor budget. Cache configurations also diverge: the EPYC offers 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB shared L3 cache. The Threadripper provides 64 KB of L1 per core, 512 KB of L2 per core, and 64 MB of L3. The EPYC's L3 cache is four times larger, which can be decisive for workloads with large working sets.

Clock speeds favor the Threadripper. Its base clock of 4.10 GHz and boost clock of 4.50 GHz both exceed the EPYC's 3.50 GHz base and 3.90 GHz boost. Despite this frequency disadvantage, the EPYC still wins every benchmark, pointing to its core count and cache advantage as the deciding factors. Power envelopes are close: the EPYC draws 240 W TDP, the Threadripper 280 W.

Memory support is identical in capacity and bandwidth: both use DDR4 across an eight-channel bus with 204.8 GB/s of bandwidth, and both support ECC memory. PCIe connectivity also matches at Gen 4, though the Threadripper's specification notes 128 lanes from the CPU only, while the EPYC's lane count is unspecified in the data. Both target the server and workstation market segment, and both remain in active production. The EPYC launched in April 2020, the Threadripper in March 2022, making the Threadripper a newer design by roughly two years.

Where Each One Wins

The AMD EPYC 7F52 wins every recorded benchmark comparison. In all six Cinebench tests, spanning R15, R20, and R23 with both multicore and single-core modes, the EPYC holds a 2.7% advantage. Its strengths are rooted in a 16-core, 32-thread configuration with a 256 MB L3 cache, which gives it an edge in heavily threaded workloads such as multi-scene rendering, simulation, and data processing that can utilize the larger cache pool. The EPYC also leads in average benchmark score at 10159 versus 9348, and it ranks one percentile higher at 66 versus 65.

The AMD Ryzen Threadripper PRO 5945WX has no benchmark wins in the recorded data, but its profile suggests different strengths. Its higher base and boost clocks, 4.10 GHz and 4.50 GHz respectively, paired with the newer Zen 3 architecture, allow it to nearly match the EPYC despite having 25% fewer cores. In workloads that are lightly threaded and sensitive to clock speed, the Threadripper's frequency advantage could narrow the gap further than the 2.7% seen in these tests. The larger transistor count of 16,600 million and the four-die design indicate a more complex chip layout, which may benefit workloads that spread across multiple memory controllers. The Threadripper also has a newer release date, March 2022 versus April 2020, meaning it incorporates more recent design improvements.

For tasks dominated by core count and cache capacity, such as long-running server-side rendering or database operations with large working sets, the EPYC 7F52 is the better choice based on its consistent benchmark wins. For workstation tasks that lean on single-threaded responsiveness or that can exploit the Zen 3 architecture's higher per-core efficiency, the Threadripper PRO 5945WX offers a compelling alternative, even though it does not win any of the recorded comparisons.

The Verdict

The data points to a clear but narrow winner. The AMD EPYC 7F52 outperforms the AMD Ryzen Threadripper PRO 5945WX in every recorded benchmark, taking all six Cinebench tests with a 2.7% margin each time. Its 16 cores, 32 threads, and 256 MB L3 cache provide the structural advantages that drive these results. The EPYC also holds a higher average benchmark score of 10159 against 9348 and a better percentile ranking of 66 versus 65.

The Threadripper PRO 5945WX, while losing every head-to-head matchup, demonstrates that Zen 3's architectural improvements are substantial. With only 12 cores and 24 threads, it comes within 2.7% of the EPYC across the board, and its higher clocks of 4.10 GHz base and 4.50 GHz boost suggest it could be competitive in scenarios not captured by these Cinebench tests. Its newer release date and significantly larger transistor count of 16,600 million point to a more modern design.

Buyers who prioritize raw multicore throughput, large cache capacity, and a higher average benchmark score should choose the EPYC 7F52. Buyers who value newer architecture, higher clock speeds, and the potential for better single-threaded performance in unmeasured workloads may prefer the Threadripper PRO 5945WX, provided they accept the 2.7% deficit in all recorded comparisons. The EPYC is the safer pick based on the available data; the Threadripper is the more speculative choice with a stronger architectural foundation.
