AMD EPYC 7351 vs AMD Ryzen Threadripper 1920X Comparison

The AMD EPYC 7351 and AMD Ryzen Threadripper 1920X are both 14 nm Zen processors manufactured by GlobalFoundries, but they target different market segments. The EPYC 7351 is a 16-core server/workstation part on AMD Socket SP3, while the Threadripper 1920X is a 12-core desktop part on AMD Socket SP3r2. The recorded benchmark data shows the EPYC 7351 winning all six head-to-head Cinebench matchups, though by narrow margins of 0.4% to 0.5%.

Head-to-Head Benchmarks

The head-to-head results cover six Cinebench tests, and the EPYC 7351 wins every one of them. In Cinebench R15 multi-core, the EPYC scores 1989 against 1979 for the Threadripper, a 0.5% lead. In R15 single-core, the EPYC scores 280 against 279, a 0.4% lead. In R20 multi-core, the EPYC scores 8291 against 8248, a 0.5% lead. In R20 single-core, the EPYC scores 1170 against 1164, a 0.5% lead. In R23 multi-core, the EPYC scores 19742 against 19640, a 0.5% lead. In R23 single-core, the EPYC scores 2787 against 2772, a 0.5% lead. The win count stands at 6 to 0.

The margins are consistent but small. Four of the six tests show exactly 0.5%, and the R15 single-core test shows 0.4%. The Threadripper 1920X runs at a base clock of 3.50 GHz and a boost clock of 4.00 GHz, well above the EPYC's 2.40 GHz base and 2.90 GHz boost. Despite that clock advantage, the EPYC still edges ahead in every test. The EPYC's 16 cores and 32 threads, combined with 64 MB of shared L3 cache, appear to offset the Threadripper's higher clocks.

The average benchmark scores reinforce the head-to-head results. The EPYC 7351 has an average benchmark score of 5710, while the Threadripper 1920X averages 5306. The EPYC sits at the 61st percentile of all CPUs, and the Threadripper sits at the 60th. The EPYC's nearest rivals in the database are the AMD EPYC 7F32 with an average score of 5703 (0.1% behind), the AMD Ryzen Threadripper 2920X at 5730 (0.4% ahead), the Intel Core i9-7920X at 5673 (0.7% behind), and the Intel Xeon W-2175 at 5770 (1% ahead). The Threadripper's nearest rivals are the Intel Core i9-9900X at 5301 (0.1% behind), the AMD EPYC 7281 at 5315 (0.2% ahead), the Intel Core i9-10900KF at 5316 (0.2% ahead), and the Intel Core i9-13900TE at 5342 (0.7% ahead). The EPYC's average score places it slightly above the Threadripper's, and its nearest-rival field includes higher-scoring parts like the Xeon W-2175, while the Threadripper's nearest rivals cluster closer to its own score.

FAQ

Q: Which processor wins the head-to-head benchmark suite?

A: The AMD EPYC 7351 wins all six Cinebench comparisons. It leads in R15 multi-core (1989 vs 1979), R15 single-core (280 vs 279), R20 multi-core (8291 vs 8248), R20 single-core (1170 vs 1164), R23 multi-core (19742 vs 19640), and R23 single-core (2787 vs 2772). The final win count is 6 to 0.

Q: How large are the performance differences between the two?

A: The margins are narrow. Four of the six head-to-head tests show a 0.5% delta, and the R15 single-core test shows 0.4%. The average benchmark scores are 5710 for the EPYC and 5306 for the Threadripper, with the EPYC at the 61st percentile and the Threadripper at the 60th.

Q: What memory bandwidth do the two processors support?

A: The EPYC 7351 uses an eight-channel DDR4 memory bus with 170.6 GB/s of bandwidth. The Threadripper 1920X uses a quad-channel DDR4 bus with 85.3 GB/s. The EPYC also supports ECC memory, while the Threadripper does not.

Q: Do the two processors have the same core and thread counts?

A: No. The EPYC 7351 has 16 cores and 32 threads, while the Threadripper 1920X has 12 cores and 24 threads. Both use the Zen architecture and a 14 nm process from GlobalFoundries.

Q: What is the launch MSRP of the Threadripper 1920X?

A: The Threadripper 1920X has a launch MSRP of $799. The EPYC 7351 has no listed launch MSRP in the database.

Q: Which processor has a higher clock speed?

A: The Threadripper 1920X has a base clock of 3.50 GHz and a boost clock of 4.00 GHz. The EPYC 7351 has a base clock of 2.40 GHz and a boost clock of 2.90 GHz. Despite the lower clocks, the EPYC wins all six head-to-head benchmarks.

Architecture Differences

Both processors are built on the Zen architecture at 14 nm by GlobalFoundries, but they diverge in several key areas. The EPYC 7351 uses the Naples codename and belongs to the EPYC 7001 series, while the Threadripper 1920X uses the Whitehaven codename and belongs to the 1000 series. The EPYC is classified as a Server/Workstation part, while the Threadripper is a Desktop part.

The transistor counts differ substantially. The EPYC 7351 has 4,800 million transistors on a single 213 mm² die. The Threadripper 1920X has 9,600 million transistors across two 213 mm² dies. This dual-die design gives the Threadripper more total silicon area, but it does not translate into a benchmark win in the recorded data.

Cache configurations also differ. Both have 96 KB of L1 cache per core and 512 KB of L2 cache per core. The EPYC has 64 MB of shared L3 cache, while the Threadripper has 32 MB of L3. The EPYC's larger L3 cache is a likely contributor to its consistent, if narrow, benchmark lead.

Memory support is a major differentiator. The EPYC 7351 uses an eight-channel DDR4 memory bus with 170.6 GB/s of bandwidth and supports ECC memory. The Threadripper 1920X uses a quad-channel DDR4 bus with 85.3 GB/s of bandwidth and does not support ECC. The EPYC's memory bandwidth is exactly double the Threadripper's, which matters for memory-intensive server workloads.

The sockets differ as well. The EPYC uses AMD Socket SP3, while the Threadripper uses AMD Socket SP3r2. Both support PCIe Gen 3, but the Threadripper lists 60 lanes (CPU only) in the database, while the EPYC's PCIe lane count is not specified in the recorded data. Both processors have an unlocked multiplier.

The release dates are close. The EPYC 7351 was released on 2017-06-28, and the Threadripper 1920X on 2017-08-09. Both are listed as Active in production status. The TDP values also differ slightly: 170 W for the EPYC and 180 W for the Threadripper.

The Verdict

The benchmark data is unambiguous: the AMD EPYC 7351 wins every head-to-head Cinebench test against the AMD Ryzen Threadripper 1920X. The margins are small, between 0.4% and 0.5%, but they are consistent across single-core and multi-core workloads. The EPYC's 16 cores, 32 threads, and 64 MB of L3 cache give it an edge over the Threadripper's 12 cores, 24 threads, and 32 MB of L3, even though the Threadripper runs at substantially higher clock speeds.

The EPYC 7351 is the better choice for server and workstation deployments where ECC memory, eight-channel bandwidth at 170.6 GB/s, and the larger L3 cache are priorities. The Threadripper 1920X, with its higher clocks and desktop market segment, is positioned for desktop use, but the recorded data shows it trailing the EPYC in every measured benchmark. The Threadripper's appeal rests on its desktop platform and dual-die design rather than on measured performance.

For buyers who need maximum memory bandwidth and ECC support, the EPYC 7351 is the clear pick. For desktop users who prioritize the Threadripper's higher base and boost clocks, the data still shows the EPYC ahead. The average benchmark scores reinforce this: 5710 for the EPYC versus 5306 for the Threadripper, with the EPYC at the 61st percentile and the Threadripper at the 60th. The EPYC also holds its own against a stronger nearest-rival field, including the Intel Xeon W-2175 at 5770 and the Intel Core i9-7920X at 5673, while the Threadripper's nearest rivals, such as the Intel Core i9-9900X at 5301 and the AMD EPYC 7281 at 5315, sit closer to its own score.
