The two Passmark single-thread entries are duplicates: both list 4168 for AMD and 4415 for Intel. Intel’s largest win is Find Prime Numbers, 330 to 126, a 61.8% margin. AMD’s largest win is Integer Math, 107173 to 85922, a 24.7% margin. The closest result is Random String Sorting, where Intel leads by only 0.2%, 40931 to 40860. Intel also leads the multithread test, 34171 to 31485, and the single-thread test, 4415 to 4168.

Architecture Differences

AMD uses the Zen 5 architecture with the Gorgon Point codename. Its generation label is Ryzen AI PRO 400, which the database lists as Zen 5 / Zen 5c. Intel uses the Arrow Lake architecture with the Arrow Lake-H codename, under the Ultra 9 generation label. Both chips are built by TSMC, but on different nodes: AMD at 4 nm, Intel at 3 nm. AMD’s die size is 233 mm²; Intel’s die size is not recorded.

The core layouts differ sharply. AMD has 10 cores and 20 threads, so its thread count is double its core count. Intel has 16 cores and 16 threads, so its thread count matches its core count. Intel has a higher base clock, 2.90 GHz versus 2.00 GHz, and a higher boost clock, 5.40 GHz versus 5.00 GHz. Intel is also rated at a higher TDP, 45 W versus 28 W.

Cache allocations are different at every level. Intel provides 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. AMD provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of L3 cache. Memory support is similar in type: both accept DDR5 and LPDDR5X over a dual-channel memory bus. Intel lists 102.4 GB/s of memory bandwidth and ECC support as true; AMD lists 89.6 GB/s and ECC support as false.

Connectivity also differs. AMD uses PCIe Gen 4 with 16 CPU lanes, while Intel uses PCIe Gen 5 with 8 CPU lanes. The integrated graphics are different as well: AMD pairs the CPU with a Radeon 890M, while Intel uses Arc Graphics 140T. The sockets are not interchangeable: AMD uses AMD Socket FP8, Intel uses Intel BGA 2049. Release dates also differ, with AMD dated 2026-01-04 and Intel dated 2025-01-12.

The Verdict

The head-to-head Passmark data favors Intel. Intel wins the multithread test, the single-thread test, floating point math, physics, data encryption, find prime numbers, extended instructions, and random string sorting. AMD wins integer math and data compression. On the shared tests, Intel is the stronger general compute part, with particularly large leads in prime number finding, floating point math, physics, and encryption.

The database ranking tells a different story. AMD sits in the 93rd percentile of all CPUs with an average benchmark score of 62498. Intel sits in the 86th percentile with an average score of 38312. These averages are not directly comparable, because the AMD record contains Passmark tests only, while the Intel record also contains Cinebench and Geekbench results. Still, the percentile gap is large: 93 versus 86.

Nearest-rival data reinforces the distinction. AMD’s average score sits 0.4% below Intel Core Ultra 7 255HX at 62738, 0.5% below AMD Ryzen AI Embedded P185 at 62839, 0.9% below Intel Core i7-13790F at 63080, and 1.1% above Intel Core i9-13900KF at 61841. Intel’s average score sits 0.1% below Intel Core 9 270H at 38335, 0.1% above Intel Core i5-13600HX at 38261, 0.2% below Intel Xeon w3-2525 at 38392, and 0.2% above AMD Ryzen 7 250 at 38221.

The data supports a split verdict. For the workloads covered by the shared Passmark tests, Intel is the stronger processor. For overall database position, AMD ranks higher. A buyer weighing the common benchmark results would favor Intel; a buyer looking at the all-CPU percentile would favor AMD.
