AMD EPYC 7601 vs AMD Ryzen Threadripper 3960X Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen Threadripper 3960X and the AMD EPYC 7601 is decisively one-sided. Across all six recorded Cinebench tests, the Ryzen Threadripper 3960X takes the win, with the EPYC 7601 failing to claim a single head-to-head victory. The margin is consistent and substantial, hovering around 56% in every test.

In Cinebench R15 multi-core, the Threadripper 3960X scores 4692 against the EPYC 7601's 3003, a 56.2% advantage. The single-core R15 result tells the same story: 662 versus 423, a 56.5% lead. Moving to Cinebench R20, the multi-core score of 19553 for the Threadripper overshadows the EPYC's 12516, again a 56.2% difference. The single-core R20 result shows 2760 against 1766, a 56.3% margin.

The pattern holds in the more demanding Cinebench R23 tests. The Threadripper 3960X posts 46557 in multi-core, while the EPYC 7601 manages 29800, a 56.2% gap. In single-core R23, the scores are 6572 and 4207 respectively, another 56.2% difference. The consistency of these deltas, all within a narrow band of 56.2% to 56.5%, suggests the performance advantage is structural rather than workload-specific.

Looking at the broader database averages, the Threadripper 3960X holds an average benchmark score of 9284, placing it in the 65th percentile of all CPUs. Its nearest rivals include the Intel Xeon Platinum 8280M at 9260 (0.3% behind), the Intel Core i5-10300H at 9243 (0.4% behind), the Intel Core i7-1165G7 at 9235 (0.5% behind), and the Intel Xeon Gold 5320 at 9234 (0.5% behind). These are tight margins, indicating the Threadripper sits in a crowded performance tier.

The EPYC 7601, by contrast, records an average benchmark score of 8619, also in the 65th percentile. Its nearest rivals are markedly different in character: the Intel Core i7-8565U at 8665 (0.5% ahead), the Intel Core i7-10510U at 8580 (0.5% behind), the Intel Core i5-8250U at 8577 (0.5% behind), and the Intel Core i5-8265U at 8568 (0.6% behind). The EPYC's rivals are all low-power mobile parts, which contextualizes its standing: it is a server chip competing in average score territory with efficient laptop processors, while the Threadripper competes with high-end Xeon and mobile H-series parts.

The head-to-head data leaves no ambiguity. The Threadripper 3960X outperforms the EPYC 7601 by more than half in every recorded test, and the gap is uniform across single-core and multi-core workloads.

Architecture Differences

The two processors come from different generations of AMD design. The Ryzen Threadripper 3960X uses the Zen 2 architecture under the codename Castle Peak, built on a 7 nm process at TSMC. The EPYC 7601 uses the original Zen architecture under the codename Naples, built on a 14 nm process at GlobalFoundries. This process node difference, 7 nm versus 14 nm, is a primary driver of the performance gap.

The transistor counts reflect the generational leap. The Threadripper 3960X integrates 15,200 million transistors across a die configuration of 4x 74 mm². The EPYC 7601 integrates 4,800 million transistors on a single 213 mm² die. The Threadripper's multi-die approach and higher transistor budget enable its superior throughput.

Core and thread counts differ in an interesting way. The EPYC 7601 actually has more cores: 32 cores and 64 threads, versus 24 cores and 48 threads on the Threadripper 3960X. Despite having fewer cores, the Threadripper wins every multi-core benchmark by a wide margin, proof of the per-core efficiency gains of Zen 2 over the original Zen.

Clock speeds tell a similar story. The Threadripper 3960X has a base clock of 3.80 GHz and a boost clock of 4.50 GHz. The EPYC 7601 has a base clock of 2.20 GHz and a boost clock of 3.20 GHz. The Threadripper's clocks are substantially higher on both ends, which explains its single-core dominance.

Cache hierarchies also differ. The Threadripper 3960X has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 128 MB of L3 cache. The EPYC 7601 has 96 KB of L1 cache per core, 512 KB of L2 cache per core, but only 64 MB of shared L3 cache. The Threadripper's L3 cache is twice the size of the EPYC's.

Memory support diverges significantly. Both support DDR4, but the Threadripper 3960X uses a quad-channel memory bus with a bandwidth of 102.4 GB/s, while the EPYC 7601 uses an eight-channel memory bus with a bandwidth of 170.6 GB/s. The EPYC has the advantage here, offering nearly 67% more memory bandwidth. Additionally, the EPYC 7601 supports ECC memory, while the Threadripper 3960X does not.

PCIe generations also differ. The Threadripper 3960X supports PCIe Gen 4, while the EPYC 7601 is limited to PCIe Gen 3. The Threadripper also uses the AMD Socket TRX4, whereas the EPYC 7601 uses AMD Socket SP3. The Threadripper's multiplier is unlocked, as is the EPYC's. Neither chip includes integrated graphics.

The market positioning reinforces these differences. The Threadripper 3960X is a desktop part with a release date of 2019-11-24, while the EPYC 7601 is a server or workstation part released on 2017-06-28. The Threadripper is the newer, more advanced design.

Cache configurations differ in L1 and L3. The Threadripper has 64 KB of L1 per core and 128 MB of L3, while the EPYC has 96 KB of L1 per core and 64 MB of shared L3. Both have 512 KB of L2 per core.

Memory support shows a split: both use DDR4, but the Threadripper has a quad-channel bus with 102.4 GB/s bandwidth, while the EPYC has an eight-channel bus with 170.6 GB/s bandwidth. The Threadripper does not support ECC memory; the EPYC does. The Threadripper uses PCIe Gen 4, while the EPYC uses PCIe Gen 3.

The market segments are Desktop for the Threadripper and Server/Workstation for the EPYC. The release dates are 2019-11-24 for the Threadripper and 2017-06-28 for the EPYC.

The Verdict

The benchmark data indicates that the AMD Ryzen Threadripper 3960X is the stronger performer in every recorded test. It leads the EPYC 7601 by 56.2% to 56.5% across all six Cinebench benchmarks, covering both single-core and multi-core workloads. Its higher clock speeds, newer Zen 2 architecture, and 7 nm process give it a decisive edge despite having 8 fewer cores.

The EPYC 7601 retains advantages in specific server-oriented features. It supports ECC memory, which the Threadripper does not, and it offers a wider eight-channel memory bus with 170.6 GB/s of bandwidth compared to the Threadripper's quad-channel 102.4 GB/s. For workloads that depend heavily on memory bandwidth or require ECC for data integrity, the EPYC 7601 has a functional edge.

The Threadripper 3960X is the choice for raw compute performance on the desktop, where its higher clocks and larger 128 MB L3 cache deliver superior results in both lightly threaded and fully threaded applications. The EPYC 7601 is the server part with more cores, more memory channels, and ECC support, suited to environments where those features outweigh raw benchmark scores.

The data does not support choosing the EPYC 7601 for performance reasons. The Threadripper 3960X wins every head-to-head benchmark by a consistent margin, and its average benchmark score of 9284 sits above the EPYC's 8619. The EPYC's relevance lies in its server-specific capabilities, not its computational throughput as measured in these tests.
