Architecture Differences

The AMD Ryzen AI 5 PRO 440 uses the Zen 5 architecture under the Gorgon Point codename, built on a 4 nm TSMC process node. The die size is 195 mm². The Intel Core Ultra 7 255H uses the Arrow Lake architecture under the Arrow Lake-H codename, built on a 3 nm TSMC process node, with no die size recorded. The AMD chip belongs to the Ryzen AI PRO 400 generation, while the Intel chip belongs to Core Ultra Series 2.

The core designs differ sharply. AMD delivers 6 cores and 12 threads with 80 KB of L1 cache per core and 1 MB of L2 cache per core. Intel delivers 16 cores and 16 threads with 192 KB of L1 cache per core and 3 MB of L2 cache per core. The L3 cache also differs: AMD provides 8 MB, while Intel provides 24 MB shared. The AMD processor relies on simultaneous multithreading to reach 12 threads from 6 cores, whereas the Intel processor uses 16 physical cores without any thread doubling.

Memory support is similar in type, with both supporting DDR5 and LPDDR5X over dual-channel buses, but the bandwidth differs. AMD lists 89.6 GB/s, Intel lists 102.4 GB/s. PCIe support diverges: AMD uses Gen 4 with 16 lanes (CPU only), while Intel uses Gen 5 with 20 lanes (CPU only). Integrated graphics also differ, with AMD pairing the Radeon 840M and Intel pairing Arc Graphics 140T. Both processors use a 28 W TDP, both are locked (multiplier unlocked is false), and both target the mobile market segment. AMD uses the AMD Socket FP8, Intel uses Intel BGA 2049.

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Core Ultra 7 255H across all 11 PassMark comparisons. The largest margin comes in the find prime numbers test, where Intel scores 303 against AMD's 77, a 74.6% advantage. That result indicates a substantial gap in integer-heavy single-threaded workloads. The floating point math test shows a similarly large divide: Intel scores 98796 versus AMD's 42934, a 56.5% lead. The physics test also favors Intel heavily, with a score of 2254 versus 1119, a 50.4% difference.

The multithread test confirms the pattern. Intel's 30703 beats AMD's 21054 by 31.4%. Data encryption shows Intel at 23395 versus AMD's 12418, a 46.9% gap. Random string sorting gives Intel 36058 against AMD's 27252, a 24.4% lead. Extended instructions show Intel at 23755 and AMD at 18456, a 22.3% margin. Data compression lands at 298850 for Intel and 256420 for AMD, a 14.2% difference. Integer math shows a tighter race: Intel scores 77975, AMD scores 65991, a 15.4% gap. Single-thread performance records Intel at 4317 and AMD at 3785, a 12.3% advantage.

These numbers indicate that Intel leads in every measured category, but the margin varies widely. The smallest deltas appear in single-thread performance and integer math, both near 12% to 15%. The largest deltas appear in prime number finding and floating point math, both above 55%. The Intel chip's edge in multithreaded and physics tests suggests that the extra cores translate directly into workload throughput.

Where Each One Wins

The Intel Core Ultra 7 255H wins every recorded head-to-head comparison, so the use-case split comes down to the size of the advantage rather than any reversal. For workloads that rely on prime number computation, floating point math, or physics simulation, the Intel chip delivers margins above 50% over the AMD chip. Those tasks benefit from the higher core count and the larger cache pool. The 74.6% lead in prime number finding and the 56.5% lead in floating point math indicate that Intel's architecture handles heavily parallel numeric workloads with a clear edge.

For data encryption and extended instruction workloads, Intel leads by 46.9% and 22.3% respectively. These results suggest that the Intel chip is the stronger choice for security-related processing and for code that uses specialized instruction sets. For multithreaded general workloads, Intel's 31.4% lead in the multithread test and its 24.4% lead in random string sorting point to broad productivity advantages. Data compression shows a smaller but still decisive 14.2% lead for Intel.

The AMD Ryzen AI 5 PRO 440 does not record any wins, but its closest margins reveal where it is less disadvantaged. In single-thread performance, Intel leads by only 12.3%, the smallest gap in the dataset. Integer math shows a 15.4% gap, also relatively narrow. The AMD chip's 87th percentile ranking versus Intel's 83rd percentile reflects that the AMD processor's average score across all benchmarks, including those outside the head-to-head set, sits higher than the Intel chip's average. That ranking comes from the full benchmark suite, where AMD's 41208 average exceeds Intel's 33537.

The Verdict

The benchmark data delivers a straightforward conclusion: the Intel Core Ultra 7 255H is the faster processor in every measured head-to-head comparison. The 11 wins out of 11 comparisons establish a consistent performance advantage that spans single-threaded, multithreaded, numeric, and memory-intensive tasks. The largest leads, exceeding 50% in prime number finding, floating point math, and physics, make the Intel chip the clear choice for computational workloads that scale with core count and cache size.

The AMD Ryzen AI 5 PRO 440 offers a different profile. Its average benchmark score of 41208 places it in the 87th percentile, above the Intel chip's 83rd percentile and its 33537 average. That ranking indicates that the AMD processor performs well in the broader benchmark database, even though it loses every direct comparison to the Intel chip in this matchup. The AMD chip's closest results come in single-thread performance and integer math, where the Intel lead narrows to roughly 12% to 15%.

Purchasers choosing between these two mobile processors should weigh the measured performance gap against the full benchmark context. The Intel Core Ultra 7 255H delivers the higher raw scores in all direct tests, with a 31.4% lead in multithread and a 12.3% lead in single-thread. The AMD Ryzen AI 5 PRO 440 holds a higher overall average score and percentile, but that advantage does not translate into any head-to-head win. The data supports selecting the Intel chip for workloads that need maximum throughput, while the AMD chip's higher average benchmark score suggests it maintains competitiveness across a wider range of tests outside this direct comparison.
