AMD EPYC 9554P vs Intel Core Ultra 7 155U Comparison

Head-to-Head Benchmarks

The recorded benchmark data presents an unusually lopsided comparison. Across all six shared Cinebench tests, the AMD EPYC 9554P wins outright, with deltas ranging from 433.8% to 825%. There is no test in the head-to-head set where the Intel Core Ultra 7 155U takes the lead.

Starting with multi-core workloads, the gap is at its widest. In Cinebench R23 multi-core, the EPYC 9554P scores 89,490 against 9,674.5 for the Core Ultra 7 155U. That is a delta of 825%, meaning the AMD part delivers more than nine times the multi-threaded render performance. The Cinebench R20 multi-core result tells a similar story: 37,585 versus 5,765, a 552% advantage. In Cinebench R15 multi-core, the EPYC 9554P posts 9,020 against 1,585, a 469.1% lead.

Single-core results also favor the EPYC 9554P, though the margins are slightly smaller in percentage terms than the multi-core extremes. In Cinebench R23 single-core, the EPYC 9554P scores 12,633 versus 1,666 for the Intel part, a 658.3% delta. Cinebench R20 single-core shows 5,305 against 813, a 552.5% difference. Cinebench R15 single-core has the EPYC 9554P at 1,273 and the Core Ultra 7 155U at 238.5, a 433.8% lead.

It is worth remembering the single-core results for the Intel Core Ultra 7 155U appear unusually low relative to its boost clock. The data shows a boost clock of 4.80 GHz, yet the recorded Cinebench R23 single-core score is 1,666. That is far below what the database typically records for a processor with that clock speed. The EPYC 9554P, by contrast, has a lower boost clock of 3.75 GHz but scores 12,633 in the same test. The discrepancy likely reflects power and thermal constraints on the mobile part, but the database does not include enough information to confirm the cause. What matters for this comparison is the recorded result: the EPYC 9554P wins every shared test by a wide margin.

The overall average benchmark scores reflect the same ordering. The EPYC 9554P has an average benchmark score of 21,899, while the Core Ultra 7 155U averages 21,174. That is a much smaller gap than the head-to-head Cinebench tests suggest, because the average includes different test sets. The EPYC 9554P's average is drawn from Geekbench and Cinebench tests, while the Core Ultra 7 155U's average includes PassMark tests that are not part of the shared head-to-head set. Both processors sit at the 75th percentile among all CPUs in the database.

The nearest rivals in the database place both parts in similar overall performance territory. The EPYC 9554P's nearest rival is the AMD EPYC 9534 with an average score of 21,900 and a delta of 0%. The Intel Core Ultra 7 155U's nearest rival is the AMD Ryzen 5 7530U at 21,133 with a delta of 0.2%. These figures show that, on average, the two processors belong to the same broad performance class, even though their head-to-head Cinebench results are dramatically different. This is a reminder that average scores across different test suites can obscure large per-workload differences.

The Verdict

The data points to a clear division of purpose. The AMD EPYC 9554P is a server and workstation processor with 64 cores, 128 threads, a 360 W TDP, and a launch MSRP of $7104. The Intel Core Ultra 7 155U is a mobile processor with 12 cores, 14 threads, a 15 W TDP, and a launch MSRP of $490. These are not competing products in the same market segment, and the benchmark results reflect that.

For multi-threaded rendering, simulation, or any workload that scales across cores, the EPYC 9554P is the only choice from this data. Its Cinebench R23 multi-core score is 825% higher than the Core Ultra 7 155U. Even in single-core Cinebench tests, where the mobile part's higher boost clock might be expected to help, the EPYC 9554P leads by at least 433.8%. The Intel part cannot match the EPYC 9554P in any shared benchmark.

The Core Ultra 7 155U wins only in the sense of operating within a far lower power envelope. Its 15 W TDP versus 360 W means it is designed for platforms where the EPYC 9554P would be physically and thermally impossible to deploy. The database does not include power-efficiency benchmarks, so a direct performance-per-watt comparison cannot be made from the recorded data. But the TDP figures alone show that the two parts target entirely different physical environments.

Buyers should choose based on platform and workload, not on raw score alone. If the workload is multi-core compute and the platform can accommodate a 360 W server processor, the EPYC 9554P is overwhelmingly faster in every recorded test. If the platform is a thin-and-light mobile device, the Core Ultra 7 155U is the only viable option between the two, despite its lower scores.

Where Each One Wins

The AMD EPYC 9554P wins all six shared Cinebench tests. Its largest margin is in Cinebench R23 multi-core at 825%, followed by Cinebench R23 single-core at 658.3%. The smallest margin is in Cinebench R15 single-core at 433.8%, which is still a dominant lead. In multi-core tests specifically, the EPYC 9554P's 64-core, 128-thread configuration produces scores that the 12-core, 14-thread Core Ultra 7 155U cannot approach.

The Intel Core Ultra 7 155U does not win any shared benchmark, but it has its own recorded strengths in the PassMark suite, which is not part of the head-to-head set. In PassMark data compression, it scores 177,122; in integer math, 57,564; in floating point math, 40,256; in random string sorting, 19,767; in multithread, 16,382; in data encryption, 11,333; in extended instructions, 9,903; in single-thread, 3,372; and in physics, 1,084. These are standalone figures with no corresponding EPYC 9554P results in the database, so they cannot be used for direct comparison. They do, however, indicate that the Core Ultra 7 155U is a capable mobile processor for everyday tasks, with particularly strong data compression and integer math results relative to its own other scores.

The use-case split is therefore straightforward. The EPYC 9554P is for server racks, workstations, and compute-heavy environments where multi-core throughput is paramount. The Core Ultra 7 155U is for laptops and compact mobile systems where the 15 W TDP and integrated Arc Xe-LPG 64EU graphics are the relevant features. The database does not include any graphics benchmarks, so the integrated GPU's performance cannot be quantified here, but its presence is a notable difference: the EPYC 9554P has no integrated graphics.
