Where Each One Wins

The benchmark data splits cleanly along workload type. The AMD EPYC 7413 dominates in every multithreaded and throughput-oriented test recorded, winning 9 of 11 head-to-head comparisons. Its largest victories come in data encryption, physics, and prime number finding, where the delta exceeds 100 percent. The EPYC's 24 cores and 48 threads provide a decisive advantage in parallel workloads that scale with core count, such as integer math, floating point math, and data compression.

The AMD Ryzen 7 PRO 9755 wins in both single-thread tests, taking the passmark single-thread and passmark singlethread entries with identical scores. Its 5.4 GHz boost clock, enabled by the smaller 4 nm process and Zen 5 architecture, gives it a significant per-core performance lead. This makes it the better choice for workloads that rely heavily on single-core responsiveness, such as certain database queries, latency-sensitive applications, or lightly threaded scientific tasks.

In terms of average benchmark scores, the EPYC 7413 records 80041, while the Ryzen 7 PRO 9755 records 75738. Both sit at the 95th percentile among all CPUs in the database, meaning they outperform nearly all other processors in the aggregate. However, the EPYC's higher average score, combined with its lead in 9 of 11 tests, indicates that for bulk processing and multitasking, the EPYC is the stronger tool. The Ryzen wins where speed per thread matters more than thread count.

The data also shows that the Ryzen's single-thread dominance does not translate into multithreaded wins. In the passmark multithread test, the EPYC scores 50641, which is 30.8 percent higher than the Ryzen's 38721. Even in the floating point math test, which often favors modern high-clock designs, the EPYC leads by 45.9 percent. This suggests that the Ryzen's architectural advantages are real but insufficient to overcome the EPYC's core and thread count advantage in parallel workloads.

Architecture Differences

The two processors represent different architectural generations and design goals. The EPYC 7413 is part of the EPYC 7003 series, based on the Zen 3 architecture with the codename Milan. It uses AMD Socket SP3 and is built on a 7 nm process from TSMC. The die is composed of four separate dies, each measuring 81 mm², with a total transistor count of 16,600 million. The larger transistor budget supports the 24-core configuration and the massive 128 MB shared L3 cache.

The Ryzen 7 PRO 9755 belongs to the 9000 series, based on Zen 5 architecture with the codename Granite Ridge. It uses AMD Socket AM5 and is built on a 4 nm process, also from TSMC. Its die is a single 70.6 mm² piece with 8,315 million transistors. The smaller process node and newer architecture allow higher clock speeds, but the physical die is far smaller, reflecting the lower core count.

The cache hierarchies diverge significantly. The EPYC allocates 64 KB of L1 and 512 KB of L2 per core, plus a shared 128 MB L3. The Ryzen has a larger per-core L1 at 80 KB and 1 MB L2, but only 32 MB of shared L3. The EPYC's larger L3 is typical for server parts, designed to hold data for many threads. The Ryzen's per-core cache is larger, likely to feed its high clock speeds with lower latency.

Memory support also reflects the design split. The EPYC uses DDR4 with an eight-channel memory bus, delivering 204.8 GB/s of bandwidth, which is essential for feeding 48 threads. The Ryzen uses DDR5 with a dual-channel bus, providing 89.6 GB/s. Both support ECC memory, which is important for server and workstation reliability.

PCIe connectivity differs as well. The EPYC offers Gen 4 with 128 lanes from the CPU, while the Ryzen provides Gen 5 with 24 lanes. The EPYC's lane count is far higher, suitable for many storage cards, GPUs, or network adapters in a server chassis. The Ryzen's Gen 5 lanes are faster per lane, but the total lane count is lower.

The Ryzen includes integrated Radeon Graphics, while the EPYC has no integrated graphics. This is typical for server processors, which usually rely on a discrete GPU or a baseboard management controller for display.

Specification Differences

The two processors differ in almost every major specification. The EPYC 7413 has 24 cores and 48 threads, compared to 8 cores and 16 threads on the Ryzen 7 PRO 9755. Base clock is 2.65 GHz for the EPYC and 3.80 GHz for the Ryzen. Boost clock is 3.60 GHz for the EPYC and 5.40 GHz for the Ryzen. The EPYC has a TDP of 180 watts, while the Ryzen has a lower TDP of 120 watts.

Sockets differ: SP3 for the EPYC, AM5 for the Ryzen. Process node: 7 nm for the EPYC, 4 nm for the Ryzen. Transistors: 16,600 million for the EPYC, 8,315 million for the Ryzen. Die size: 4x 81 mm² for the EPYC, 70.6 mm² for the Ryzen. L1 cache per core: 64 KB for the EPYC, 80 KB for the Ryzen. L2 cache per core: 512 KB for the EPYC, 1 MB for the Ryzen. L3 cache shared: 128 MB for the EPYC, 32 MB for the Ryzen.

Memory: DDR4 for the EPYC, DDR5 for the Ryzen. Memory bus: eight-channel for the EPYC, dual-channel for the Ryzen. Memory bandwidth: 204.8 GB/s for the EPYC, 89.6 GB/s for the Ryzen. PCIe: Gen 4 with 128 lanes for the EPYC, Gen 5 with 24 lanes for the Ryzen. Integrated graphics: none for the EPYC, Radeon Graphics for the Ryzen. Release dates: the EPYC was released in March 2021, the Ryzen in June 2026. The EPYC has a launch MSRP of $1825; the Ryzen has no recorded launch MSRP. Both have locked multipliers and active production status.

The market segment for both is listed as server and workstation, though the Ryzen's form factor and socket suggest a desktop-oriented workstation. The EPYC is designed for dense multi-socket servers, given its SP3 socket and high lane count. The Ryzen targets AM5-based workstations.

Head-to-Head Benchmarks

The head-to-head data shows that the EPYC 7413 wins 9 of 11 comparisons, with the Ryzen 7 PRO 9755 taking the other 2. The margins are often large.

In passmark data compression, the EPYC scores 715,616 against the Ryzen's 467,988, a 52.9 percent advantage. This test reflects how quickly a processor compresses data streams, which is a common server workload. The EPYC's extra cores and larger L3 cache clearly help.

In passmark data encryption, the EPYC scores 48,492 versus the Ryzen's 22,577, a 114.8 percent advantage. This is the largest percentage lead in the entire set, showing a more than doubling of throughput. Encryption workloads often parallelize well, so the EPYC's thread count is the key factor.

In passmark extended instructions, the EPYC scores 45,696 against the Ryzen's 38,976, a 17.2 percent advantage. This test measures performance with AVX and other instructions, and the EPYC's margin is modest but consistent.

In passmark find prime numbers, the EPYC scores 397 versus the Ryzen's 197, a 101.5 percent advantage. Prime number finding is a classic threaded workload, and the EPYC doubles the Ryzen's score.

In passmark floating point math, the EPYC scores 118,881 against the Ryzen's 81,456, a 45.9 percent advantage. This test uses heavy floating point operations across many threads, where the EPYC's core count wins.

In passmark integer math, the EPYC scores 215,629 against the Ryzen's 122,411, a 76.2 percent advantage. Integer math is a common server workload, and the EPYC's lead is substantial.

In passmark multithread, the EPYC scores 50,641 against the Ryzen's 38,721, a 30.8 percent advantage. This aggregate test mixes several workloads, and the EPYC's lead is solid.

In passmark physics, the EPYC scores 4,708 against the Ryzen's 2,257, a 108.6 percent advantage. Physics simulations often scale with threads, and the EPYC more than doubles the Ryzen.

In passmark random string sorting, the EPYC scores 81,134 against the Ryzen's 49,326, a 64.5 percent advantage. Sorting is memory and cache sensitive, and the EPYC's 128 MB L3 likely helps.

The only wins for the Ryzen are the two single-thread tests, which are identical in measurement. The Ryzen scores 4,606 in both, while the EPYC scores 2,400, giving the Ryzen a 47.9 percent advantage. This is a large margin, reflecting the Ryzen's 5.4 GHz boost clock and Zen 5 per-core efficiency.

Overall, the head-to-head data tells a clear story. The EPYC 7413 is a throughput monster for parallel workloads, while the Ryzen 7 PRO 9755 is a per-core speed champion. The EPYC's average benchmark score of 80,041 and the Ryzen's 71,738 place both at the 95th percentile, but the EPYC's 9-2 win record and larger margins in most tests make it the stronger overall processor in the database, especially for server-like workloads. The Ryzen's single-thread dominance is noteworthy, but it does not translate into any multithreaded victory.
