AMD Ryzen 9 8940HX vs Intel Core Ultra X7 368H Comparison

The Verdict

The recorded data separates these two mobile processors into distinct roles. The AMD Ryzen 9 8940HX wins 9 of the 15 head-to-head benchmark comparisons, while the Intel Core Ultra X7 368H takes 6. The AMD part posts an average benchmark score of 81103, placing it in the 95th percentile of all CPUs. The Intel part averages 40518, landing in the 87th percentile. That average score gap is roughly double, and it shows in the heavy multithreaded workloads.

The Ryzen 9 8940HX is the choice for sustained multi-core throughput. It leads by 88.3% in Cinebench R15 multicore and by 15.2% in Cinebench R23 multicore. Its PassMark multithread score of 49731 beats the Intel part's 32956 by 50.9%. The Intel Core Ultra X7 368H counters with a substantial single-core advantage: 3984 versus 1917 in Cinebench R23 singlecore, a 51.9% lead, and 401 versus 292 in Cinebench R15 singlecore, a 27.2% lead. The Intel chip also wins PassMark physics, find prime numbers, and the single-thread tests by smaller margins.

The data indicates two different design targets. The AMD processor uses 16 cores and 32 threads with a 55 W TDP. The Intel processor uses 16 cores and 16 threads with a 25 W TDP. The AMD part has double the thread count, which explains its dominance in parallel workloads. The Intel part compensates with higher single-core efficiency and lower power draw, which suits lighter, latency-sensitive tasks. The verdict from the data: the Ryzen 9 8940HX for compute-heavy parallel work, the Core Ultra X7 368H for single-thread performance and power-constrained mobile use.

Where Each One Wins

The AMD Ryzen 9 8940HX wins every multithreaded throughput test in the comparison set. In Cinebench R23 multicore it scores 32521 against 28221, a 15.2% margin. In PassMark integer math it scores 189221 against 88083, a 114.8% lead, the largest single delta in the entire comparison. Data compression also favors AMD heavily: 650984 versus 312927, a 108% difference. Random string sorting follows with 75381 versus 38093, a 97.9% gap. Encryption shows a 55.9% lead with 39318 versus 25228. Extended instructions show an 86.2% lead with 47802 versus 25669. Floating point math is closer but still AMD's, 113921 versus 105681, a 7.8% margin. The Cinebench R15 multicore test delivers the biggest relative win for AMD at 88.3%, with scores of 5355 and 2844.

The Intel Core Ultra X7 368H wins the single-core and latency-sensitive tests. Its Cinebench R23 singlecore score of 3984 crushes the AMD's 1917, a 51.9% advantage. Cinebench R15 singlecore goes Intel's way too, 401 versus 292, a 27.2% lead. PassMark physics favors Intel, 2857 versus 2104, a 26.4% margin. The find prime numbers test goes to Intel, 321 versus 251, a 21.8% lead. PassMark single thread is close: 4005 versus 3874, only a 3.3% margin for Intel. The Intel part's wins are narrower in aggregate than AMD's, but they point to a clear strength in workloads that depend on per-core speed rather than raw thread count.

Architecture Differences

The two processors come from different manufacturing and design lineages. The AMD Ryzen 9 8940HX uses the Zen 4 architecture under the Dragon Range codename, built on a 5 nm process at TSMC. It uses 13,140 million transistors across a die size of 2x 71 mm². The Intel Core Ultra X7 368H uses the Panther Lake architecture, also its codename, built on a 3 nm process at Intel. The Intel part has no transistor or die size data recorded in the database.

Cache layouts differ substantially. The AMD part provides 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3. The Intel part provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The AMD chip has far more total L3, while the Intel chip has larger per-core L1 and L2 allocations.

Core and thread counts are the same at 16 cores, but the AMD part supports 32 threads while the Intel part supports 16. The AMD base clock is 2.40 GHz with a boost of 5.30 GHz. The Intel base clock is 2.00 GHz with a boost of 5.00 GHz. The AMD TDP is 55 W, the Intel TDP is 25 W. The AMD chip uses AMD Socket FL1, the Intel chip uses Intel BGA 2540. The AMD multiplier is unlocked, the Intel multiplier is locked.

Memory support diverges. The AMD part uses DDR5 over a dual-channel bus with 83.2 GB/s of bandwidth. The Intel part uses LPDDR5X over a dual-channel bus with 153.6 GB/s of bandwidth, nearly double the recorded figure. PCIe lanes also differ: the AMD part provides Gen 5 with 28 lanes (CPU only), while the Intel part provides Gen 5 with 4 lanes (CPU only). Integrated graphics are Radeon 610M on the AMD side and Arc B390 on the Intel side. Neither supports ECC memory. Both are listed as Active production, mobile market segment, with the AMD releasing on 2025-04-22 and the Intel on 2026-01-04.
