AMD EPYC 4545P vs AMD Ryzen 7 PRO 9755 Comparison

The AMD EPYC 4545P is the clear performance leader in this comparison, winning 9 of 11 head-to-head benchmarks and delivering decisive multi-threaded advantages, while the AMD Ryzen 7 PRO 9755 takes only the single-thread crown. The Ryzen 7 PRO 9755 edges out the EPYC 4545P in single-thread performance by 6.7%, but the EPYC 4545P’s doubling of cores and threads translates to massive wins in every other workload category, making it the choice for heavily threaded server and workstation tasks. The Ryzen 7 PRO 9755 is the pick for single-thread-sensitive applications, while the EPYC 4545P dominates everything else.

The Verdict

The data is unambiguous: the AMD EPYC 4545P is the superior processor for multi-threaded workloads, and the AMD Ryzen 7 PRO 9755 is the better option for single-thread-bound tasks. With 16 cores and 32 threads versus the Ryzen’s 8 cores and 16 threads, the EPYC 4545P posts a 27.6% higher Passmark multithread score (53504 vs 38721) and a 42.7% higher integer math score (213485 vs 122411). The Ryzen 7 PRO 9755’s only benchmark victories are in Passmark single-thread tests, where it scores 4606 against the EPYC’s 4318, a 6.7% advantage. Both processors sit at the 95th percentile among all CPUs and have nearly identical average benchmark scores (75738 for the Ryzen, 75373 for the EPYC), but the EPYC 4545P’s wins are far more decisive in magnitude. Users who need raw parallel processing power — database compression, encryption, physics simulation, or floating point math — should choose the EPYC 4545P. Users whose primary workloads rely on per-core speed, such as legacy or lightly threaded applications, should pick the Ryzen 7 PRO 9755.

Architecture Differences

The architectural divide is stark. The Ryzen 7 PRO 9755 uses the Granite Ridge codename with a monolithic 4 nm TSMC die measuring 70.6 mm² and containing 8,315 million transistors. The EPYC 4545P, codenamed Grado, uses a dual-die design on the same 4 nm TSMC process, with two 70.6 mm² dies totaling 16,630 million transistors. Both are Zen 5 architecture, but the EPYC 4545P’s dual-die arrangement doubles the core count and cache capacity. The Ryzen 7 PRO 9755 features 8 cores and 16 threads, while the EPYC 4545P offers 16 cores and 32 threads. The EPYC 4545P also doubles the L3 cache: 64 MB shared versus the Ryzen’s 32 MB shared. L1 and L2 caches are identical at 80 KB per core and 1 MB per core, respectively. Both processors support DDR5 memory on a dual-channel bus with 89.6 GB/s bandwidth and both support ECC memory. PCIe capabilities match at Gen 5 with 24 lanes (CPU only), and both integrate Radeon Graphics. The EPYC 4545P has a significantly lower TDP of 65 watts versus the Ryzen 7 PRO 9755’s 120 watts, despite having twice the cores — a notable efficiency advantage. The EPYC 4545P’s base clock is 3.00 GHz versus the Ryzen’s 3.80 GHz, but both boost to 5.40 GHz. The Ryzen 7 PRO 9755 has no launch MSRP listed, while the EPYC 4545P carries a launch MSRP of $549.

Head-to-Head Benchmarks

The EPYC 4545P’s dominance is comprehensive across compute-heavy workloads. In Passmark data compression, the EPYC 4545P scores 636279 against the Ryzen 7 PRO 9755’s 467988, a 26.4% lead. Data encryption shows an even bigger gap: 37598 versus 22577, a 40% advantage. Extended instructions favor the EPYC 4545P by 15.7% (46231 vs 38976). Prime number finding is 32.5% faster on the EPYC 4545P (292 vs 197). Floating point math results in a 35.6% win for the EPYC 4545P (126505 vs 81456). The largest single delta is in integer math: the EPYC 4545P scores 213485 versus 122411, a 42.7% margin. The multithread test shows a 27.6% advantage for the EPYC 4545P (53504 vs 38721). Physics simulation favors the EPYC 4545P by 30.8% (3260 vs 2257). Random string sorting is 33.2% faster on the EPYC 4545P (73850 vs 49326). The Ryzen 7 PRO 9755 wins only the two single-thread tests, scoring 4606 in both Passmark single-thread and single-thread variants against the EPYC 4545P’s 4318, a 6.7% margin each. Notably, the Ryzen 7 PRO 9755’s average benchmark score (75738) is slightly higher than the EPYC 4545P’s (75373), but this is driven by the single-thread outliers; the EPYC 4545P’s wins are far more substantial in absolute score differences.

Where Each One Wins

The AMD EPYC 4545P wins in every multi-threaded and throughput-oriented scenario. Its 16 cores and 32 threads, combined with 64 MB of L3 cache, deliver decisive advantages in data compression (26.4% faster), data encryption (40% faster), floating point math (35.6% faster), integer math (42.7% faster), and multithread performance (27.6% faster). The EPYC 4545P is the clear choice for server virtualization, database workloads, scientific computing, video rendering, and any application that can utilize more than 8 cores. Its lower TDP of 65 watts versus 120 watts makes it particularly attractive for dense server deployments where power efficiency matters. The EPYC 4545P also wins in physics simulation (30.8% faster) and random string sorting (33.2% faster), making it suitable for financial modeling and data processing.

The AMD Ryzen 7 PRO 9755 wins exclusively in single-thread performance, with a 6.7% advantage in both Passmark single-thread tests. This makes it the better choice for lightly threaded applications, legacy software that doesn’t scale across cores, or workloads where per-core latency is the bottleneck. Its higher base clock of 3.80 GHz versus the EPYC 4545P’s 3.00 GHz supports this advantage. The Ryzen 7 PRO 9755’s single-die design with fewer transistors (8,315 million versus 16,630 million) may also offer lower latency for memory access in single-threaded tasks. For users running a mix of workloads, the Ryzen 7 PRO 9755’s 95th percentile ranking and near-identical average benchmark score (75738) to the EPYC 4545P (75373) indicate it remains a strong all-rounder, but the EPYC 4545P’s 9-to-2 benchmark win ratio makes it the default recommendation for most server and workstation tasks.
