Architecture Differences

The core designs differ in architecture, process node, cache layout, and platform support. AMD uses Zen 5 with the Gorgon Point codename, from the Ryzen AI 400 generation (Zen 5 / Zen 5c), on a 4 nm TSMC process with a 195 mm² die. Intel uses Arrow Lake with the Arrow Lake-S codename, from the Core Ultra Series 2 generation, on a 3 nm TSMC process with a 243 mm² die and 17,800 million transistors.

Core and cache organization differs. AMD has 8 cores, 16 threads, 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3. Intel has 10 cores, 10 threads, 192 KB L1 per core, 3 MB L2 per core, and 20 MB shared L3. The Intel part therefore has more cores and larger caches per core, while the AMD part has more threads.

Platform features separate them further. AMD is a mobile part on AMD Socket FP8, with a 28 W TDP, DDR5 and LPDDR5X memory support, 89.6 GB/s bandwidth, ECC memory support, PCIe Gen 4 with 16 CPU lanes, and a Radeon 860M. Intel is a desktop part on Intel Socket 1851, with a 65 W TDP, DDR5 memory, 102.4 GB/s bandwidth, no ECC support, PCIe Gen 5 with 20 CPU lanes, and no integrated graphics.

Head-to-Head Benchmarks

The head-to-head record favors Intel by volume: 10 wins to 5. AMD's strongest result is PassMark integer math: 88531 vs 66417, a 33.3 percent lead. AMD also wins Cinebench R23 multi-core (18316 vs 16467, 11.2 percent), Cinebench R23 single-core (2038 vs 1893, 7.7 percent), Cinebench R15 multi-core (2713 vs 2660, 2.0 percent), and PassMark data compression (315906 vs 310843, 1.6 percent).

Intel's largest win is PassMark find prime numbers: 352 vs 89, a -74.7 percent delta. Intel also leads PassMark floating point math (92554 vs 54447, -41.2 percent), PassMark physics (2430 vs 1578, -35.1 percent), PassMark data encryption (22648 vs 16247, -28.3 percent), PassMark extended instructions (28027 vs 22400, -20.1 percent), PassMark multithread (31004 vs 26350, -15.0 percent), PassMark random string sorting (37325 vs 35648, -4.5 percent), Cinebench R15 single-core (287 vs 215, -25.1 percent), and PassMark single-thread (4397 vs 3901, -11.3 percent). The database records PassMark single_thread and singlethread as the same score.

The Verdict

Overall ranking favors AMD. Its average benchmark score of 39485 places it at the 87th percentile. In its nearest rival set, it trails the AMD Ryzen 7 PRO 8840HS by 0.3 percent, leads the AMD Ryzen 7 PRO 8845HS by 0.4 percent, leads the AMD EPYC 4245P by 0.7 percent, and trails the AMD Ryzen 7 9800X3D by 0.7 percent. The Intel Core Ultra 5 225F, at 37313 and the 85th percentile, trails the Intel Core i9-13900HK by 0.3 percent and leads the AMD Ryzen 7 7735H by 0.4 percent, the Intel Core i7-13700 by 0.5 percent, and the AMD Ryzen 7 160 by 0.5 percent.

The data supports a split verdict. For workloads following Cinebench R23, integer math, and data compression, the AMD part is the stronger selection. For workloads following PassMark multithread, floating-point math, encryption, extended instructions, prime-number finding, physics, and single-thread tests, the Intel part is the stronger selection. AMD supplies the only integrated GPU and the lower TDP (28 W vs 65 W). Intel supplies the higher base clock (3.30 GHz vs 2.00 GHz), larger L3 cache (20 MB vs 8 MB), and higher memory bandwidth (102.4 GB/s vs 89.6 GB/s).
