That is a 2.2% advantage for AMD, and it appears in both the passmark_single_thread and passmark_singlethread entries in the database. This is a narrow win, but it is consistent across both recorded entries, indicating the AMD core delivers slightly better per-thread throughput in this particular workload.

Where Each One Wins

The Intel Core 9 273PE dominates every heavily threaded workload in the database. Cinebench R15, R20, and R23 multicore tests all show the Intel chip ahead by roughly 36%. PassMark multithread confirms this, with Intel ahead by 38.1%. The physics test, which typically scales with thread count and core count, shows the largest gap at 63%. Prime number finding also favors Intel heavily at 61.6%. Data compression, encryption, floating point math, and integer math all favor Intel by margins ranging from 30.3% to 58%. These results indicate the Intel chip is the stronger choice for workloads that can use many threads, such as rendering, numerical simulation, and large data transformations.

The AMD Ryzen 5 PRO 8640U wins only the PassMark single-thread test, and only by 2.2%. This is a narrow margin, but it does suggest the AMD architecture has a slight edge in lightly threaded workloads that depend on single-core responsiveness. The Cinebench single-core tests do not support this conclusion, however, as Intel leads those by 36.1% to 36.2%. The PassMark single-thread result appears to be workload-specific, possibly reflecting differences in instruction handling or memory latency that favor the AMD design in that particular benchmark.

For users working with highly parallel tasks, the Intel Core 9 273PE is clearly the stronger performer across the recorded data. For workloads that are strictly single-threaded, the AMD chip shows a small advantage in one test, but the Cinebench single-core results contradict that, showing Intel with a substantial lead. The overall pattern is clear: Intel wins the vast majority of tests, and the margins are large in most cases.

Architecture Differences

The AMD Ryzen 5 PRO 8640U uses the Zen 4 architecture under the Hawk Point codename, part of the 8000 series. It is built on a 4 nm process at TSMC, with 25,000 million transistors on a 178 mm² die.
