AMD EPYC 72F3 vs AMD Ryzen Threadripper 2950X Comparison

The AMD EPYC 72F3 and AMD Ryzen Threadripper 2950X present a fascinating study in generational contrast versus raw core count. The EPYC 72F3 is a modern Zen 3 server part with a massive L3 cache, while the Threadripper 2950X is a Zen+ desktop enthusiast chip with double the cores. Benchmark results consistently favor the older Threadripper across every single test, yet the architectural chasm between the two suggests the story is more complex than a simple scoreboard.

Head-to-Head Benchmarks

The head-to-head data is unambiguous: the AMD Ryzen Threadripper 2950X wins all six Cinebench comparisons. The margins are remarkably uniform, with the Threadripper leading by 7.5% or 7.6% in every test. In Cinebench R15 multi-core, the Threadripper scores 2523 against the EPYC’s 2334, a 7.5% advantage. The single-core R15 result shows 356 versus 329, a 7.6% lead. This pattern repeats in R20, where the Threadripper posts 10516 versus 9728 (7.5%), and in the single-core R20 test, it leads 1484 to 1373 (7.5%). The newer R23 benchmark continues the trend, with the Threadripper achieving 25040 multi-core and 3535 single-core, while the EPYC manages 23164 and 3270 respectively, again a 7.5% gap.

What is striking is the consistency of the delta. The EPYC’s Zen 3 architecture, which typically offers higher instructions per clock than Zen+, does not translate into a single-core victory. The Threadripper’s higher boost clock of 4.40 GHz versus the EPYC’s 4.10 GHz likely explains this, as the 7.6% single-core advantage aligns closely with the 7.3% clock speed difference. In multi-core workloads, the Threadripper’s 16 cores and 32 threads simply overpower the EPYC’s 8 cores and 16 threads, despite the newer architecture. The average benchmark score further reinforces this, with the Threadripper at 6647 and the EPYC at 6700, a negligible 0.8% difference that places both in the 62nd percentile of all CPUs. Notably, the EPYC’s nearest rival list includes the Threadripper itself with a deltaPct of 0.8%, indicating that in aggregate performance, they are virtually tied.

Architecture Differences

The underlying designs could not be more different. The EPYC 72F3 is built on a 7 nm process at TSMC, packing 33,200 million transistors across an 8-chiplet design with each die measuring 81 mm². The Threadripper 2950X uses GlobalFoundries’ 12 nm process, featuring 9,600 million transistors on two dies of 213 mm² each. This generational leap in process technology gives the EPYC a significant efficiency advantage, though it does not manifest in benchmark wins here.

Cache configuration is the most dramatic divergence. The EPYC boasts 256 MB of shared L3 cache, an enormous pool designed to keep server workloads local. The Threadripper has a comparatively modest 32 MB L3. Per-core L1 cache also differs, with the EPYC offering 64 KB per core versus the Threadripper’s 96 KB per core. Both share 512 KB L2 per core. This massive L3 advantage on the EPYC is a clear indicator of its server intent, where large working sets and virtualization benefit from extensive caching.

Memory and I/O further separate them. The EPYC supports eight-channel DDR4 memory with a theoretical bandwidth of 204.8 GB/s, while the Threadripper is limited to quad-channel with 93.9 GB/s. The EPYC also supports ECC memory, a critical feature for server reliability, which the Threadripper lacks. PCIe connectivity shows a similar gap: the EPYC provides Gen 4 with 128 lanes, while the Threadripper offers Gen 3 with 60 lanes. The sockets are also different, with the EPYC using AMD Socket SP3 and the Threadripper using SP3r2, meaning they are not interchangeable. The EPYC’s multiplier is locked, while the Threadripper’s is unlocked, reflecting their respective server and desktop market segments.

FAQ

Q: Why does the Threadripper 2950X consistently outperform the EPYC 72F3 in Cinebench despite being older?

A: The Threadripper has 16 cores and 32 threads compared to the EPYC’s 8 cores and 16 threads. In all six Cinebench tests, the Threadripper leads by 7.5% or 7.6%, and its higher boost clock of 4.40 GHz versus 4.10 GHz also contributes to the single-core wins.

Q: Does the EPYC 72F3’s larger cache give it any advantage in these benchmarks?

A: The data does not show that. Despite having 256 MB of L3 cache versus the Threadripper’s 32 MB, the EPYC loses every Cinebench test. The benchmark results indicate that core count and clock speed are more decisive factors in these specific workloads.

Q: What are the key memory differences between the two processors?

A: The EPYC 72F3 supports eight-channel DDR4 memory with 204.8 GB/s bandwidth and ECC memory. The Threadripper 2950X supports quad-channel DDR4 with 93.9 GB/s bandwidth and does not support ECC. This makes the EPYC far more suited to memory-intensive server tasks.

Q: Are these two CPUs compatible with the same motherboards?

A: No. The EPYC 72F3 uses AMD Socket SP3, while the Threadripper 2950X uses AMD Socket SP3r2. They also differ in PCIe support, with the EPYC offering Gen 4 (128 lanes) and the Threadripper offering Gen 3 (60 lanes), so they require different platforms.

Q: Which processor has a higher average benchmark score overall?

A: The EPYC 72F3 has an average benchmark score of 6700, while the Threadripper 2950X scores 6647. The difference is 0.8%, placing them both in the 62nd percentile of all CPUs. Despite the Threadripper winning every head-to-head Cinebench test, the aggregate score slightly favors the EPYC.

Q: Is the Threadripper’s unlocked multiplier a significant advantage?

A: The Threadripper 2950X has an unlocked multiplier, while the EPYC 72F3 is locked. This allows for manual overclocking on the Threadripper, potentially increasing its performance beyond the already winning benchmark scores, though the data does not include overclocked results.

The Verdict

The benchmark data is decisive: for pure Cinebench performance, the AMD Ryzen Threadripper 2950X is the winner. It beats the EPYC 72F3 in every single test, with a consistent 7.5% multi-core and 7.6% single-core margin. The Threadripper’s 16 cores and 32 threads provide a clear advantage in these workloads, and its higher boost clock secures single-core wins. The EPYC’s strengths lie elsewhere, in its 256 MB L3 cache, eight-channel ECC memory support, and PCIe Gen 4 connectivity, none of which are measured by Cinebench. The average benchmark scores are nearly identical, with the EPYC at 6700 and the Threadripper at 6647, a 0.8% difference, so the choice depends entirely on the workload. For desktop applications and Cinebench-style rendering, the Threadripper is superior. For server environments requiring massive memory bandwidth, ECC reliability, and extensive I/O, the EPYC is the appropriate platform, even if its raw Cinebench scores are lower.

The EPYC has a locked multiplier, while the Threadripper’s is unlocked. Release dates are 2021-03-14 for the EPYC and 2018-08-30 for the Threadripper.

Where Each One Wins

The AMD Ryzen Threadripper 2950X wins in every benchmark category recorded. It takes the multi-core tests in Cinebench R15 (2523 vs 2334), R20 (10516 vs 9728), and R23 (25040 vs 23164). It also wins all single-core tests, including R15 (356 vs 329), R20 (1484 vs 1373), and R23 (3535 vs 3270). The Threadripper’s victories are directly attributable to its higher core count and boost clock, making it the clear choice for Cinebench-style rendering and multi-threaded desktop workloads. It also offers an unlocked multiplier for overclocking.

The AMD EPYC 72F3, despite losing all head-to-head benchmarks, wins in platform-level capabilities. It provides 256 MB of L3 cache, which is eight times larger than the Threadripper’s 32 MB, and offers eight-channel DDR4 memory with 204.8 GB/s bandwidth, more than double the Threadripper’s 93.9 GB/s. The EPYC supports ECC memory, which the Threadripper does not. It also provides PCIe Gen 4 with 128 lanes versus Gen 3 with 60 lanes. For server applications, virtualization, and memory-bandwidth-intensive workloads, these features are critical, even though they do not appear in Cinebench scores. The EPYC’s average benchmark score of 6700, slightly higher than the Threadripper’s 6647, also suggests that in a broader mix of tests, the EPYC may be competitive, though the data provided only includes Cinebench results. The EPYC is the correct choice for enterprise reliability and scalability, while the Threadripper is the winner for raw compute performance in desktop-class applications.
