The Threadripper also dominates in encryption and extended instruction workloads. PassMark data encryption records 157,137 for the Threadripper versus 11,110 for the Ryzen AI 5 435, a delta of -92.9%. Extended instructions record 228,959 versus 16,197, also a delta of -92.9%. Find prime numbers records 769 versus 58, a delta of -92.5%.

Multithreaded synthetic scores show the same gap. PassMark multithread records 141,641 for the Threadripper versus 19,000 for the Ryzen AI 5 435, a delta of -86.6%. PassMark physics records 8,001 versus 1,075, also a delta of -86.6%.

The closest contest appears in the single-threaded tests. PassMark single-thread records 4,537 for the Threadripper versus 3,734 for the Ryzen AI 5 435, a delta of -17.7%. That remains a clear win for the Threadripper, but it is far narrower than the multicore margins. Cinebench R23 single-core shows 18,427 versus 1,816, a delta of -90.1%, and Cinebench R15 single-core shows 1,857 versus 260, a delta of -86%.

The Verdict

The recorded data does not show a single benchmark where the AMD Ryzen AI 5 435 beats the AMD Ryzen Threadripper 9980X. The Threadripper holds a 99th percentile standing against all CPUs in the database, while the Ryzen AI 5 435 sits at the 80th percentile. The average benchmark score of 321,753 for the Threadripper versus 28,128 for the Ryzen AI 5 435 places them in different performance tiers entirely.

The closest comparison in the entire data set is single-thread performance, where the Threadripper leads by 17.7%. Every other test shows a gap of at least 86%. The Ryzen AI 5 435 cannot compensate with platform features, since the Threadripper also offers more memory bandwidth, more PCIe lanes, more cache, and a higher boost clock.

The Ryzen AI 5 435 remains an active, current mobile processor with a modest 28 W TDP and integrated graphics. The Threadripper 9980X is an active, current desktop processor with a 350 W TDP, no integrated graphics, and an unlocked multiplier. The data indicates the Threadripper is the stronger processor in every measured workload.

Single-threaded performance also belongs to the Threadripper, with PassMark single-thread at 4,537 versus 3,734, Cinebench R23 single-core at 18,427 versus 1,816, and Cinebench R15 single-core at 1,857 versus 260.

The AMD Ryzen AI 5 435 has no benchmark wins in the recorded data. Its position in the database is defined by its 80th percentile ranking and an average score of 28,128, placing it near the Intel Core i5-13490F at 28,185 (-0.2%), the Intel Core i5-14500T at 28,065 (0.2%), the AMD Ryzen 5 PRO 8500GE at 28,054 (0.3%), and the AMD Ryzen 5 PRO 5655G at 28,032 (0.3%). Its advantages are structural rather than performance-based: a 28 W TDP, integrated Radeon 840M graphics, and support for LPDDR5X memory make it a mobile-oriented part. The Threadripper 9980X, by contrast, sits near the AMD Ryzen Threadripper PRO 9985WX at 320,749 (0.3%), the Intel Xeon 6781P at 315,524 (2%), the AMD EPYC 9575F at 311,774 (3.2%), and the AMD EPYC 9734 at 310,619 (3.6%).
