AMD EPYC 9554P vs AMD Ryzen 5 7535U Comparison

The Verdict

The benchmark data presents a clear and decisive outcome: the AMD EPYC 9554P wins all six head-to-head comparisons against the AMD Ryzen 5 7535U. The EPYC 9554P is the dominant choice for any workload that scales with core count or raw computational throughput. The Ryzen 5 7535U is a mobile processor, and the recorded measurements reflect its positioning as a lower-power, portable option. The EPYC 9554P is the unequivocal choice for server and workstation tasks where performance is the sole priority. The Ryzen 5 7535U remains the only viable selection in the database for mobile or ultra-thin laptop scenarios, but it loses every single benchmark comparison in this pairing.

Where Each One Wins

The data shows that the AMD EPYC 9554P wins in every recorded category, from single-core to multi-core. The Ryzen 5 7535U records zero wins in the head-to-head benchmarks. The EPYC 9554P is the winner for computational workloads, including rendering, simulation, and data processing. Its advantage is most pronounced in multi-core tests, where its 64-core configuration is leveraged to a far greater degree than the 6-core Ryzen 5 7535U.

The Ryzen 5 7535U does not claim a single benchmark victory. Its only potential edge over the EPYC 9554P is not measured in the benchmark suite, but is evident in its specifications: it is the only one of the two with integrated graphics (Radeon 660M), and its 28-watt TDP is drastically lower than the 360-watt TDP of the EPYC 9554P. For a system where power consumption and space are the primary constraints, the Ryzen 5 7535U is the only logical choice, but its performance is strictly lower across all recorded metrics.

Architecture Differences

The two processors represent different architectural generations and design goals. The Ryzen 5 7535U is built on the Zen 3+ architecture, codenamed Rembrandt-R, and is part of the Ryzen 5 generation. It is fabricated on a 6 nm process node at TSMC. The EPYC 9554P is built on the newer Zen 4 architecture, codenamed Genoa, and is part of the EPYC 9004 series. It uses a 5 nm process node, also from TSMC, and has a die size reported as 8x 72 mm².

The core and thread counts are starkly different. The Ryzen 5 7535U has 6 cores and 12 threads. The EPYC 9554P has 64 cores and 128 threads. The cache hierarchy also differs significantly. Both have a 64 KB L1 cache per core. The L2 cache is 512 KB per core on the Ryzen 5 7535U, while the EPYC 9554P has 1 MB per core. The L3 cache is a major differentiator: 16 MB shared on the Ryzen 5 7535U versus 256 MB shared on the EPYC 9554P. The EPYC 9554P also reports 52,560 million transistors, a figure not provided for the Ryzen 5 7535U.

Memory support is another area of divergence. Both support DDR5 memory, but the Ryzen 5 7535U uses a dual-channel memory bus with a bandwidth of 76.8 GB/s. The EPYC 9554P uses a twelve-channel memory bus, delivering a bandwidth of 460.8 GB/s, which is six times higher. Both processors support ECC memory. The PCIe capabilities are also distinct: the Ryzen 5 7535U offers Gen 4 with 20 lanes, while the EPYC 9554P offers Gen 5 with 128 lanes.

The socket types are incompatible. The Ryzen 5 7535U uses AMD Socket FP7, while the EPYC 9554P uses AMD Socket SP5. The market segments are explicitly different: the Ryzen 5 7535U is listed as Mobile, and the EPYC 9554P is listed as Server/Workstation. The release dates are also different, with the Ryzen 5 7535U released in January 2023 and the EPYC 9554P released in November 2022.

Head-to-Head Benchmarks

The head-to-head data is one-sided. The EPYC 9554P wins all six tests, with the largest deltas occurring in the multi-core Cinebench tests. In Cinebench R23 multi-core, the EPYC 9554P scores 89,490, while the Ryzen 5 7535U scores 8,591. This is a delta of -90.4%, meaning the Ryzen 5 7535U scores roughly 90% lower. The Cinebench R15 multi-core test shows a similar pattern: the EPYC 9554P scores 9,020, and the Ryzen 5 7535U scores 1,330, a delta of -85.3%.

The single-core tests also favor the EPYC 9554P, but the margins are more variable. In Cinebench R15 single-core, the EPYC 9554P scores 1,273 against 225 for the Ryzen 5 7535U, a delta of -82.3%. In Cinebench R23 single-core, the EPYC 9554P scores 12,633 versus 1,414, a delta of -88.8%. The smallest relative gap is in Geekbench single-core, where the EPYC 9554P scores 1,911 and the Ryzen 5 7535U scores 1,602, a delta of -16.2%. This indicates that while the EPYC 9554P still wins, the architectural differences are less impactful in this specific single-threaded test.

Geekbench multi-core also shows a large EPYC advantage: 17,978 versus 6,466, a delta of -64%. The data consistently shows that the EPYC 9554P's higher core count and newer architecture translate to superior performance across all recorded benchmark types. The Ryzen 5 7535U's closest performance comes in the Geekbench single-core test, but it still trails by over 16%.
