AMD EPYC 9575F vs AMD Ryzen Threadripper 9980X Comparison

Both the AMD Ryzen Threadripper 9980X and the AMD EPYC 9575F are 64-core, 128-thread Zen 5 processors aimed at extreme high-end computing, yet they carve out distinctly different identities. The Threadripper 9980X, part of the 9000 series, is a desktop part on the sTR5 socket, while the EPYC 9575F is a server/workstation processor on the SP5 platform. Benchmark data shows the Threadripper 9980X winning 11 of 17 head-to-head tests and holding a 3.2% lead in aggregate average benchmark score (321,753 vs. 311,774), but the EPYC 9575F retaliates decisively in specific server-oriented workloads, proving that the "better" chip depends entirely on the task at hand.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head results is the Threadripper 9980X’s clean sweep of every Cinebench test. Across all six Cinebench runs—R15, R20, and R23, both single-core and multi-core—the Threadripper 9980X wins by a consistent 2.2% margin. For instance, in Cinebench R23 multi-core, it scores 130,529 against the EPYC’s 127,739, and in single-core it posts 18,427 versus 18,033. This uniformity suggests a fundamental clock-speed advantage rather than architectural variation, as the Threadripper’s 5.40 GHz boost clock exceeds the EPYC’s 5.00 GHz.

The Threadripper 9980X extends its lead in several PassMark workloads, often by larger margins. The biggest win comes in extended instructions, where it scores 228,959 versus 197,484—a 15.9% advantage that indicates superior handling of advanced instruction sets. It also leads by 7.2% in data compression (2,974,534 vs. 2,773,634), 6.3% in floating point math (559,003 vs. 526,003), and 8.7% in single-thread performance (4,537 vs. 4,173). These results paint a picture of a processor that is not just faster per-core but also more efficient in compute-heavy, vectorized tasks.

However, the EPYC 9575F is far from uncompetitive. Its most dramatic victory is in PassMark physics, where it scores 20,652 against the Threadripper’s 8,001—a 61.3% lead that is by far the largest delta in the entire comparison. It also wins decisively in find prime numbers (1,215 vs. 769, a 36.7% edge) and random string sorting (348,500 vs. 292,083, a 16.2% lead). Smaller wins come in multithread (147,998 vs. 141,641, 4.3%), data encryption (162,818 vs. 157,137, 3.5%), and integer math (891,817 vs. 872,071, 2.2%). These are not marginal differences; the physics and prime-number results suggest the EPYC’s architecture is substantially better optimized for certain integer-heavy and simulation-style workloads.

Architecture Differences

Both processors share the same fundamental Zen 5 architecture, 4 nm process node from TSMC, and identical transistor counts of 66,520 million spread across 8x 70.6 mm² dies. The L3 cache is also the same size at 256 MB, though the Threadripper lists it as "256 MB" while the EPYC specifies "256 MB (shared)." The per-core L1 cache differs: the Threadripper has 64 KB per core, while the EPYC has 80 KB per core. L2 cache is identical at 1 MB per core.

The most consequential differences lie in memory and I/O. The EPYC 9575F employs a twelve-channel memory bus delivering 576.0 GB/s of bandwidth, while the Threadripper 9980X uses a quad-channel bus at 204.8 GB/s. That is a 2.8x bandwidth advantage for the EPYC, which directly explains its dominance in memory-sensitive tests like random string sorting. Similarly, the EPYC offers 128 PCIe Gen 5 lanes versus the Threadripper’s 80, making it the more expandable platform for storage and accelerators.

Clock speeds and power draw tell the opposite story. The Threadripper 9980X boosts to 5.40 GHz versus the EPYC’s 5.00 GHz, and it does so within a 350 W TDP compared to the EPYC’s 400 W. The base clocks are close (3.20 GHz vs. 3.30 GHz), but the Threadripper’s higher boost ceiling gives it the edge in single-threaded and lightly threaded tasks. The Threadripper also has an unlocked multiplier, whereas the EPYC is locked, and the two use different sockets (sTR5 vs. SP5) with different memory channels (quad vs. twelve). The EPYC launched earlier, on 2024-10-09, while the Threadripper followed on 2025-07-29.

Where Each One Wins

The Threadripper 9980X is the clear choice for workloads that depend on raw per-core performance and floating-point throughput. Its 8.7% single-thread lead and 6.3% floating-point math advantage make it well-suited for rendering engines, video encoding, and 3D modeling where individual thread speed directly impacts responsiveness and final render times. Its 15.9% lead in extended instructions also suggests it handles modern SIMD-heavy code more efficiently, which benefits scientific computing and machine learning inference tasks that rely on AVX-512-style instructions. The consistent 2.2% Cinebench wins across the board indicate that it is the better processor for content creation suites that scale well with multi-threading but still value high clocks.

The EPYC 9575F, on the other hand, is the winner in memory-bandwidth-bound and certain integer-heavy scenarios. The 61.3% physics score advantage and 36.7% prime-number lead are not subtle; they point to workloads involving collision detection, finite element analysis, or cryptographic key generation where the EPYC’s larger L1 cache and twelve-channel memory architecture shine. Its 16.2% win in random string sorting is a classic memory-latency and bandwidth test, and its 3.5% edge in data encryption aligns with server-side tasks like secure communications and database encryption. The 4.3% multithread win, despite losing all Cinebench multi-core tests, suggests the EPYC is better at keeping all 128 threads fed with data, which is critical for virtual machine hosts and large-scale database servers.

The Verdict

The data does not crown a single overall winner; it identifies two distinct tools. For a desktop workstation user running Cinebench, 3D rendering, or floating-point analysis, the Threadripper 9980X is the superior chip. It wins every rendering benchmark, offers better single-thread performance, and does so with 50 W less TDP (350 W vs. 400 W). Its 3.2% aggregate benchmark lead (321,753 vs. 311,774) and 99th percentile standing among all CPUs confirm that it is the higher-performing part on average.

However, for a server administrator running virtual machines, database workloads, or physics simulations, the EPYC 9575F is the better investment despite its lower aggregate score. The 61.3% physics win and 36.7% prime-number win are too large to ignore, and its 576.0 GB/s memory bandwidth is an absolute requirement for many enterprise workloads. The EPYC also offers more PCIe lanes (128 vs. 80) for storage expansion. The Threadripper’s 3.2% lead in average score is dwarfed by the EPYC’s massive wins in specific server tasks. Pick the Threadripper 9980X for content creation and desktop compute; pick the EPYC 9575F for data-center-style workloads that demand memory bandwidth and integer throughput.
