AMD EPYC 7551 vs AMD Ryzen Threadripper 2970WX Comparison

Where Each One Wins

The AMD EPYC 7551 and AMD Ryzen Threadripper 2970WX target completely different workloads, and the benchmark data makes that split obvious. The Ryzen Threadripper 2970WX wins every single head-to-head benchmark recorded in the database, taking all six Cinebench tests across R15, R20, and R23, in both single-core and multi-core runs. That is a clean sweep, with a consistent 16% margin in each test. The EPYC 7551, on the other hand, does not record a single win in the direct comparison, yet it still holds its own in the broader market because its strengths are not captured by consumer-oriented rendering tests.

For multi-threaded desktop workloads, video rendering, 3D simulation, and content creation, the Threadripper 2970WX is the clear choice. Its Cinebench R23 multi-core score of 26305 beats the EPYC 7551's 22096 by 16%, and the same gap repeats in R20 (11048 vs 9280) and R15 (2651 vs 2227). Single-core performance is also firmly in the Threadripper's favor, with R23 single-core at 3713 versus 3119, again a 16% advantage. Users who prioritize raw rendering throughput or interactive responsiveness in applications that scale to 24 cores will find the Threadripper substantially faster.

The EPYC 7551 is a server part, and its wins are structural rather than benchmark-driven. It offers 32 cores and 64 threads, which is 8 cores and 16 threads more than the Threadripper, and it supports eight-channel DDR4 memory with 170.6 GB/s of bandwidth. The Threadripper 2970WX uses quad-channel memory with 93.9 GB/s, so in memory-bandwidth-bound server workloads, database operations, or large-scale virtualization, the EPYC's extra channels and higher bandwidth are decisive advantages that the Cinebench suite does not measure. The EPYC also supports ECC memory, while the Threadripper does not, making the EPYC the appropriate part for reliability-critical environments.

The market percentile data places both processors at the 62nd percentile among all CPUs, meaning they are statistically equivalent in aggregate performance across the entire benchmark database. The EPYC 7551 has an average benchmark score of 6391, while the Threadripper 2970WX averages 6760, a difference of roughly 5.8% in the Threadripper's favor. But the EPYC's nearest rivals are Intel Xeon and Core parts: the Xeon D-2796TE (6510, 1.8% faster than the EPYC) and the Xeon W-2191B (6531, 2.1% faster). The Threadripper's nearest rivals are also Intel server and mobile parts: the Core i7-12700E (6776, 0.2% faster) and the Xeon Gold 6154 (6803, 0.6% faster). Both CPUs sit in a competitive cluster where small percentage differences separate them from immediate alternatives.

In short, the Threadripper 2970WX wins on every measured benchmark, especially in single-threaded and rendering tasks. The EPYC 7551 wins on server features: more cores, more memory channels, more memory bandwidth, and ECC support. Choose the Threadripper for a desktop workstation, the EPYC for a server rack.

Head-to-Head Benchmarks

The database records six direct head-to-head benchmark comparisons, and the AMD Ryzen Threadripper 2970WX wins all six by a uniform 16% margin. This consistency is notable: the delta is exactly -16% from the Threadripper's perspective in every test, regardless of whether the workload is single-core or multi-core, and regardless of the Cinebench version.

Starting with Cinebench R15, the Threadripper scores 2651 in multi-core versus the EPYC's 2227. The single-core result is 374 versus 314. Both are 16% gaps. Moving to R20, the multi-core scores are 11048 for the Threadripper and 9280 for the EPYC. Single-core is 1559 versus 1309. Again, 16%. Finally, in R23, the most recent rendering benchmark, the Threadripper reaches 26305 multi-core and 3713 single-core, while the EPYC manages 22096 and 3119.

The story is that the Threadripper 2970WX is faster in every measured metric, but the margin is identical across all tests. This suggests the difference is not workload-dependent but rather reflects a consistent per-thread performance advantage. The Threadripper's higher clock speeds (3.00 GHz base, 4.20 GHz boost) versus the EPYC's (2.00 GHz base, 3.00 GHz boost) likely explain the uniform gap. The EPYC has more cores (32 vs 24), but the Threadripper's superior clock speed and newer architecture (Zen+ vs Zen) overcome the core deficit in every Cinebench test.

There are no benchmark wins for the EPYC in the direct comparison. Its wins are architectural: eight-channel memory versus quad-channel, 170.6 GB/s versus 93.9 GB/s bandwidth, ECC support, and more cores. But in the specific rendering tests recorded, the Threadripper dominates. The Geekbench results only exist for the Threadripper (7195 multi-core, 1236 single-core), with no corresponding EPYC data, so they cannot be compared directly.

The average benchmark scores reinforce the same picture, though with a smaller margin. The Threadripper's average is 6760, the EPYC's is 6391. The nearest rivals for the EPYC are the Intel Core i9-10920X (6347, 0.7% slower), the Core i7-12800HE (6467, 1.2% faster), the Xeon D-2796TE (6510, 1.8% faster), and the Xeon W-2191B (6531, 2.1% faster). The Threadripper's nearest rivals are the Core i7-12700E (6776, 0.2% faster), Xeon Gold 6154 (6803, 0.6% faster), Xeon D-2775TE (6711, 0.7% slower), and Xeon Gold 5317 (6710, 0.7% slower). Both processors are tightly grouped among similar-performing Intel parts.

Specification Differences

The two CPUs differ in nearly every specification category. The EPYC 7551 has 32 cores and 64 threads; the Threadripper 2970WX has 24 cores and 48 threads. Base clocks are 2000 MHz for the EPYC and 3000 MHz for the Threadripper. Boost clocks are 3000 MHz and 4200 MHz respectively. The Threadripper runs at a higher TDP of 250 watts versus the EPYC's 180 watts.

The sockets are different: the EPYC uses AMD Socket SP3, while the Threadripper uses AMD Socket SP3r2. They are not interchangeable. The memory bus is eight-channel for the EPYC and quad-channel for the Threadripper, with memory bandwidth of 170.6 GB/s versus 93.9 GB/s. ECC memory is supported on the EPYC but not on the Threadripper.

The launch MSRP for the Threadripper 2970WX is $1299. The EPYC 7551 has no recorded launch MSRP in the database. The EPYC is from the EPYC 7001 series, while the Threadripper is from the 2000 series. The EPYC's part number is PS7551BDVIHAF; the Threadripper's is YD297XAZUHCAF.

The release dates differ by over a year: the EPYC launched on June 28, 2017, and the Threadripper on October 1, 2018. Both are currently marked as Active in production status. Both have unlocked multipliers, and neither has integrated graphics.

The market segments are fundamentally different: the EPYC is Server/Workstation, the Threadripper is Desktop. The PCIe interface is Gen 3 for both, but the Threadripper specifies 60 lanes (CPU only), while the EPYC listing does not specify a lane count.

Architecture Differences

The architectural divide is clear: the EPYC 7551 uses the Zen architecture on a 14 nm process node, while the Threadripper 2970WX uses Zen+ on a 12 nm node. The codenames reflect this: the EPYC is "Naples," the Threadripper is "Colfax." Both are manufactured by GlobalFoundries.

The transistor counts are dramatically different. The EPYC 7551 has 4,800 million transistors on a 213 mm² die. The Threadripper 2970WX has 19,200 million transistors across a 4x 213 mm² configuration, meaning four dies of 213 mm² each. This multi-die design is a hallmark of the Threadripper approach, allowing higher aggregate transistor counts at the cost of higher power (250 W TDP versus 180 W).

Cache configurations are similar in capacity but structured identically: both have 96 KB L1 per core and 512 KB L2 per core. The L3 cache is 64 MB shared for the EPYC and 64 MB for the Threadripper. The per-core L1 and L2 sizes are the same, which means the Threadripper's advantage comes from clock speed and architecture improvements, not cache size.

The Zen+ architecture in the Threadripper is a refined version of the original Zen used in the EPYC. The 12 nm process node is a die-shrink from the 14 nm node, which typically enables higher clock speeds at similar power. This explains the Threadripper's higher base and boost clocks (3.00 GHz and 4.20 GHz versus 2.00 GHz and 3.00 GHz). The architecture also brings better memory latency and improved instruction scheduling, though the database does not record microarchitectural details beyond the node, codename, and generation.

The EPYC's Naples generation is designed for multi-socket server platforms, with eight-channel memory and ECC support. The Threadripper's Colfax generation is a desktop part with quad-channel memory and no ECC. Both use DDR4 memory, and both support PCIe Gen 3. The Threadripper's 60 PCIe lanes (CPU only) are specified in the database, while the EPYC does not have a lane count listed.

The production status for both is Active, meaning they remain available in the market. The EPYC's 14 nm process and 213 mm² die are older technology, but the server focus with 32 cores and eight-channel memory keeps it relevant for specific workloads. The Threadripper's 12 nm process and four-die design represent a later generation with higher clocks and better single-thread performance. The data shows the Threadripper wins all rendering benchmarks, but the EPYC's server features, more cores, higher memory bandwidth, and ECC support make it the appropriate choice for memory-bound and reliability-critical applications.
