AMD EPYC 7281 vs AMD Ryzen 7 PRO 3700 Comparison

Where Each One Wins

The benchmark data presents a clear and consistent picture across every recorded Cinebench test: the AMD Ryzen 7 PRO 3700 wins all six head-to-head comparisons against the AMD EPYC 7281. This is not a narrow victory in a single workload; it is a sweep across both multi-core and single-core rendering tests, spanning three generations of the Cinebench suite.

The Ryzen 7 PRO 3700 takes the multi-core crown decisively. In Cinebench R23 multi-core, it scores 19,397 against the EPYC 7281's 18,377, a 5.6% advantage. The same pattern holds in Cinebench R20 multi-core, where the Ryzen posts 8,146 versus 7,718, and in Cinebench R15 multi-core, where it leads 1,955 to 1,852. The delta in each multi-core test hovers around 5.5% to 5.6%, remarkably consistent across all three suite versions.

Single-core performance is where the Ryzen 7 PRO 3700 stretches its lead slightly further in relative terms. In Cinebench R23 single-core, it scores 2,738 against 2,594 for the EPYC, a 5.6% margin. Cinebench R20 single-core shows 1,149 versus 1,089, and Cinebench R15 single-core shows 275 versus 261. These margins, between 5.4% and 5.6%, tell a story of architectural efficiency rather than sheer core count.

The EPYC 7281, despite offering twice the cores and threads, 16 cores and 32 threads versus 8 cores and 16 threads, cannot convert that hardware advantage into a benchmark win in these tests. Its higher 170 W TDP and server-class platform do not translate into superior Cinebench results. The data shows the Ryzen 7 PRO 3700 winning every recorded workload, making it the clear choice for applications that resemble these rendering benchmarks.

Architecture Differences

The two processors come from different generations and design philosophies. The AMD Ryzen 7 PRO 3700 is built on the Zen 2 architecture, codenamed Matisse, using a 7 nm process node fabricated by TSMC. The AMD EPYC 7281 belongs to the original Zen architecture, codenamed Naples, and uses a 14 nm process node from GlobalFoundries. This process node gap, 7 nm versus 14 nm, is a fundamental differentiator that explains much of the performance delta despite the EPYC's larger core count.

Transistor counts and die sizes reinforce the generational divide. The Ryzen 7 PRO 3700 packs 3,800 million transistors into a 74 mm² die, while the EPYC 7281 contains 4,800 million transistors across a much larger 213 mm² die. The smaller, denser 7 nm process allows the Ryzen to achieve higher clock speeds, 3.60 GHz base and 4.40 GHz boost, against the EPYC's 2.10 GHz base and 2.70 GHz boost, while consuming far less power at 65 W versus 170 W.

Cache configurations differ in structure. The Ryzen 7 PRO 3700 offers 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of L3 cache. The EPYC 7281 provides 96 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3. The L3 cache is identical in total capacity, but the per-core L1 advantage goes to the EPYC, a detail that does not prevent the Ryzen from winning every benchmark.

Platform and memory support diverge sharply. The Ryzen uses AMD Socket AM4 with dual-channel DDR4 memory and a memory bandwidth of 51.2 GB/s, and it does not support ECC memory. The EPYC uses AMD Socket SP3 with eight-channel DDR4 memory, a memory bandwidth of 170.6 GB/s, and full ECC memory support. The EPYC also supports PCIe Gen 3, while the Ryzen offers PCIe Gen 4 with 24 lanes from the CPU. The Ryzen has an unlocked multiplier; the EPYC also has an unlocked multiplier.

Market positioning and release timing separate them further. The Ryzen 7 PRO 3700 is a desktop processor from the 3000 series, released on 2019-09-29. The EPYC 7281 is a server and workstation part from the EPYC 7001 series, released on 2017-06-28. Both remain in active production status. The Ryzen belongs to the Ryzen 7 generation with the Zen 2 (Matisse) codename, while the EPYC belongs to the EPYC generation with the Zen (Naples) codename.

Head-to-Head Benchmarks

The recorded head-to-head data shows a uniform outcome: the AMD Ryzen 7 PRO 3700 wins all six tests, with every victory falling between 5.4% and 5.6%. No test goes the way of the EPYC 7281.

In Cinebench R15 multi-core, the Ryzen scores 1,955 against 1,852 for the EPYC, a 5.6% win. Cinebench R15 single-core sees the Ryzen at 275 versus 261, a 5.4% margin, the smallest relative gap in the entire comparison. Cinebench R20 multi-core gives the Ryzen 8,146 against 7,718, a 5.5% edge, and Cinebench R20 single-core gives 1,149 versus 1,089, also 5.5%. Cinebench R23 multi-core shows the largest absolute gap, 19,397 versus 18,377, again a 5.6% margin, and Cinebench R23 single-core rounds out the sweep at 2,738 versus 2,594, another 5.6% win.

The consistency of these margins is notable. Across six tests, the delta never strays beyond a 0.2 percentage point range. This suggests the performance advantage is systemic, rooted in the architectural and process node differences, rather than workload-specific. A 5.6% lead in both single-core and multi-core Cinebench R23 indicates the Ryzen's advantage applies equally to lightly threaded and heavily threaded rendering tasks.

Average benchmark scores in the broader database reinforce this outcome. The Ryzen 7 PRO 3700 holds an average benchmark score of 5,610 across all recorded tests, while the EPYC 7281 sits at 5,315. The Ryzen also ranks at the 61st percentile among all CPUs, versus the 60th percentile for the EPYC. These aggregate figures, while close, confirm the head-to-head sweep.

The nearest rivals for each processor provide context. The Ryzen 7 PRO 3700's closest competitor is the Intel Core i7-12700T, with an average score of 5,606 and a delta of 0.1%. The Intel Atom x7433RE follows at 5,601 with a 0.2% delta. The EPYC 7281's nearest rival is the Intel Core i9-10900KF at 5,316 with a 0% delta, and the AMD Ryzen Threadripper 1920X at 5,306 with a 0.2% delta. These rival comparisons show both processors operating in similar average performance territory, despite the EPYC's vastly different core count and platform.

FAQ

Q: Which processor wins in multi-core performance?

A: The Ryzen 7 PRO 3700 was released on 2019-09-29, and the EPYC 7281 was released on 2017-06-28. Both remain in active production status.

Specification Differences

The two processors differ across nearly every major specification category, reflecting their distinct market segments and generations. The Ryzen 7 PRO 3700 offers 8 cores and 16 threads, while the EPYC 7281 doubles that to 16 cores and 32 threads. Clock speeds strongly favor the Ryzen: 3.60 GHz base and 4.40 GHz boost, versus 2.10 GHz base and 2.70 GHz boost for the EPYC. Thermal design power follows the same pattern, with the Ryzen at 65 W and the EPYC at 170 W.

Socket and platform details diverge completely. The Ryzen uses AMD Socket AM4, the EPYC uses AMD Socket SP3. The Ryzen is built on the Zen 2 architecture with the Matisse codename, the EPYC on the original Zen architecture with the Naples codename. Process nodes differ by a full generation: 7 nm from TSMC for the Ryzen, 14 nm from GlobalFoundries for the EPYC.

Cache structures vary in L1 and L3 organization. The Ryzen has 64 KB of L1 per core and 32 MB of L3, while the EPYC has 96 KB of L1 per core and 32 MB of shared L3. Both share 512 KB of L2 per core. Memory support favors the EPYC on bandwidth, 170.6 GB/s versus 51.2 GB/s, and channel count, eight-channel versus dual-channel, and the EPYC supports ECC while the Ryzen does not. PCIe generations differ as well, with the Ryzen offering Gen 4 and 24 CPU lanes, against Gen 3 for the EPYC.

Market segment, release date, and part numbering distinguish the two further. The Ryzen is a desktop part from the 3000 series, released on 2019-09-29, with the part number 100-000000073. The EPYC is a server and workstation part from the EPYC 7001 series, released on 2017-06-28, with no recorded part number. Both have unlocked multipliers. The Ryzen's transistor count is 3,800 million on a 74 mm² die, while the EPYC's is 4,800 million on a 213 mm² die. Neither processor includes integrated graphics.
