Architecture Differences

The Intel Core Ultra X7 368H is built on Intel's 3 nm process at Intel's foundry, using the Panther Lake architecture. It has 16 cores and 16 threads, with 192 KB of L1 cache per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The AMD Ryzen AI 7 450 uses TSMC's 4 nm process, with the Zen 5 architecture (Gorgon Point). It has 8 cores and 16 threads, with 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The AMD die size is 195 mm², while the Intel die size is not recorded.

Memory support differs significantly. Intel supports LPDDR5X only, while AMD supports both DDR5 and LPDDR5X. Intel has a memory bandwidth of 153.6 GB/s, AMD has 89.6 GB/s. Intel does not support ECC memory, AMD does. PCIe connectivity also differs: Intel has Gen 5 with 4 lanes, AMD has Gen 4 with 16 lanes. Integrated graphics are Arc B390 on Intel and Radeon 860M on AMD. Both are mobile parts with active production status and the same release date.

The Verdict

For most workloads, the Intel Core Ultra X7 368H is the stronger choice. It wins 13 of 15 head-to-head benchmarks, including large margins in multi-core and single-core tests. The AMD Ryzen AI 7 450 only wins in data compression and integer math, with small margins. However, the AMD part offers ECC memory support and more PCIe lanes, which may matter for specific professional or server-like use cases. The Intel part also has a higher memory bandwidth, which can benefit memory-intensive tasks. Given the benchmark dominance, the Intel is the pick for general performance, while the AMD is for niche workloads.
