AMD EPYC 8224P vs AMD Ryzen 7 PRO 9755 Comparison

The AMD Ryzen 7 PRO 9755 and AMD EPYC 8224P both sit at the 95th percentile of all CPUs, but they achieve that status through radically different designs. The Ryzen 7 PRO 9755 is the single-thread champion, while the EPYC 8224P dominates nearly every multi-threaded workload. Benchmark data shows the EPYC 8224P wins 9 of 11 head-to-head comparisons, with the Ryzen 7 PRO 9755 taking only the two single-thread tests. The pick depends entirely on workload: the Ryzen for latency-sensitive, lightly-threaded tasks; the EPYC for throughput and parallel compute.

The Verdict

The AMD EPYC 8224P is the clear overall winner in this matchup. It wins 9 of the 11 shared benchmark comparisons, including decisive margins in data compression (702,065 vs 467,988, a 33.3% lead), integer math (185,556 vs 122,411, a 34% lead), and random string sorting (81,674 vs 49,326, a 39.6% lead). Its multithread score of 45,421 surpasses the Ryzen's 38,721 by 14.8%. For any workload that scales across cores, the EPYC 8224P is the superior processor.

The AMD Ryzen 7 PRO 9755 has exactly one compelling case: raw single-thread performance. Its PassMark single-thread score of 4,606 is 96.9% higher than the EPYC's 2,339. This is an enormous gap, nearly double the performance. The Ryzen also carries integrated Radeon Graphics, which the EPYC lacks entirely. If the workload is primarily single-threaded or requires a display output without a discrete GPU, the Ryzen is the only rational choice.

The average benchmark scores are nearly identical — 75,738 for the Ryzen versus 75,582 for the EPYC, a 0.2% difference. This masks the true story. The EPYC wins by large margins in throughput tests, while the Ryzen wins by an even larger margin in single-thread. The EPYC is the better all-rounder for server environments; the Ryzen is a specialist for single-thread dominance.

Architecture Differences

The two CPUs come from different generations and design philosophies. The Ryzen 7 PRO 9755 is built on the Zen 5 architecture with the Granite Ridge codename, fabricated on a 4 nm process at TSMC. The EPYC 8224P uses the Zen 4c architecture with the Siena codename, on a 5 nm process also from TSMC. The Ryzen's 4 nm node gives it a transistor-density advantage despite its smaller absolute count.

The core counts differ dramatically. The Ryzen 7 PRO 9755 has 8 cores and 16 threads, while the EPYC 8224P has 24 cores and 48 threads — three times the cores and threads. The EPYC compensates for its lower clock speeds with sheer core count. Its base clock of 2.55 GHz and boost of 3.00 GHz are far below the Ryzen's 3.80 GHz base and 5.40 GHz boost.

Cache structures also diverge. The Ryzen has 80 KB of L1 per core and 1 MB of L2 per core, with 32 MB of shared L3. The EPYC has 64 KB of L1 and 1 MB of L2 per core but doubles the shared L3 to 64 MB. The EPYC's larger L3 cache, combined with its 6-channel memory bus, supports its multi-threaded workload. The Ryzen has a dual-channel memory bus with 89.6 GB/s bandwidth; the EPYC has six-channel memory with 230.4 GB/s.

The transistor counts reflect the scale difference. The Ryzen packs 8,315 million transistors on a 70.6 mm² die. The EPYC uses 17,750 million transistors across two 73 mm² dies. This dual-die design helps explain the EPYC's higher TDP of 160 watts versus the Ryzen's 120 watts.

Head-to-Head Benchmarks

The EPYC 8224P dominates the multi-threaded landscape. Its largest win is in data compression, scoring 702,065 against the Ryzen's 467,988 — a 33.3% advantage. The encryption test shows an even wider relative gap: 46,742 versus 22,577, a 51.7% lead for the EPYC. In integer math, the EPYC's 185,556 beats the Ryzen's 122,411 by 34%. Floating-point math follows the same pattern: 104,698 versus 81,456, a 22.2% EPYC lead.

The EPYC also wins the more specialized tests. Random string sorting goes to the EPYC at 81,674 versus 49,326, a 39.6% margin. Physics tests show the EPYC at 3,236 versus 2,257 for the Ryzen, a 30.3% advantage. Extended instructions favor the EPYC at 43,614 versus 38,976, a 10.6% lead. Even find prime numbers, a test that often favors higher clock speeds, goes to the EPYC at 206 versus 197, a 4.4% margin. The multithread test, a broad measure of parallel performance, shows the EPYC ahead at 45,421 versus 38,721, a 14.8% lead.

The Ryzen 7 PRO 9755 wins the two single-thread tests decisively. Its score of 4,606 is 96.9% higher than the EPYC's 2,339. This is the largest margin in either direction across all benchmarks. The Ryzen's 5.40 GHz boost clock, versus the EPYC's 3.00 GHz, directly explains this result. No other test comes close to this level of dominance for the Ryzen.

Where Each One Wins

The AMD EPYC 8224P wins in every parallel, throughput-oriented scenario. Data compression, encryption, integer math, floating-point math, physics, and random string sorting all favor the EPYC by margins ranging from 4.4% to 51.7%. Its 24 cores and 48 threads, combined with 64 MB of L3 cache and 230.4 GB/s of memory bandwidth, make it the choice for server virtualization, database workloads, scientific computing, and any application that can utilize more than 16 threads. The EPYC's wins in multithread (14.8%), integer math (34%), and data compression (33.3%) show consistent strength across different parallel task types.

The AMD Ryzen 7 PRO 9755 wins exclusively in single-thread performance. Its 4,606 score versus 2,339 is a 96.9% advantage, which is more than double the EPYC's best win margin. This makes the Ryzen the pick for legacy software, latency-sensitive applications, gaming, and any workload that cannot scale beyond one or two cores. The Ryzen also has the integrated Radeon Graphics, which the EPYC lacks, making it suitable for workstations that need display output without a separate graphics card. The Ryzen's 5.40 GHz boost clock is its key asset.

The average scores tell a story of near-parity — 75,738 versus 75,582 — but this hides the specialization. The EPYC wins 9 benchmarks, the Ryzen wins 2. The EPYC is the safer choice for general server workloads. The Ryzen is the specialist that wins big where it wins at all.
