AMD Ryzen AI Embedded P132 vs Intel Core Ultra 7 255H Comparison

Where Each One Wins

The benchmark data presents a one-sided comparison. Across all 11 recorded head-to-head tests, the Intel Core Ultra 7 255H takes every win. The AMD Ryzen AI Embedded P132 does not record a single victory in any of the PassMark subtests, whether single-threaded or multi-threaded.

The Intel part's largest margins appear in compute-heavy workloads. The floating point math test shows the Intel processor at 98,796 versus 42,248 for the AMD chip, a 57.2% deficit. The prime number search test is even more lopsided: Intel scores 303, AMD scores 57, a gap of 81.2%. These results indicate that the Intel processor carries a substantial advantage in raw arithmetic throughput.

The AMD processor's closest result is in integer math, where it scores 62,249 against Intel's 77,975, a 20.2% difference. That remains a clear loss, but it is the smallest relative gap in the entire set. Single-thread performance also shows a narrower margin: 3,713 versus 4,317, a 14% difference. The data suggests that while the AMD chip falls behind across the board, its relative weakness is smallest in integer and single-thread tasks rather than in highly parallel floating-point work.

Multi-thread performance follows the same pattern. The PassMark multi-thread score for Intel is 30,703, for AMD it is 19,262, a 37.3% deficit. The physics test, which often scales with core count and thread count, shows Intel at 2,254 versus AMD at 1,022, a 54.7% gap. Data compression and encryption also favor Intel by 22.9% and 51.1% respectively.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI Embedded P132 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process at TSMC. The Intel Core Ultra 7 255H uses the Arrow Lake-H codename, belongs to the Core Ultra Series 2 generation, and is built on a 3 nm process, also at TSMC.

Core counts differ sharply. The AMD part has 6 cores and 12 threads. The Intel part has 16 cores and 16 threads. Notably, Intel's chip does not support simultaneous multi-threading, so its thread count equals its core count. The AMD chip uses simultaneous multi-threading to reach 12 threads from 6 cores. Despite having fewer threads, the AMD processor records a lower multi-thread score, which indicates the Intel core count advantage outweighs the AMD thread advantage.

Cache hierarchies show a significant difference. The AMD processor has 80 KB of L1 per core, 1 MB of L2 per core, and a 4 MB L3 cache. The Intel processor has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The Intel L3 cache is six times larger on a nominal basis, which likely contributes to its lead in data compression and random string sorting.

Memory bandwidth also favors Intel. Both processors support DDR5 and LPDDR5X memory over a dual-channel bus. The Intel part records 102.4 GB/s of memory bandwidth, while the AMD part records 89.6 GB/s. Both support ECC memory. PCIe connectivity differs as well: the AMD chip uses Gen 4 with 14 CPU lanes, the Intel chip uses Gen 5 with 20 CPU lanes.

Clock speeds show a mixed picture. Both have a base clock of 2.00 GHz. The Intel boost clock reaches 5.10 GHz, while the AMD boost clock reaches 4.50 GHz. The TDP for both is 28 watts. The integrated graphics also differ: AMD uses the Radeon 840M, Intel uses the Arc Graphics 140T. The AMD processor uses the AMD Socket FP8, the Intel processor uses Intel BGA 2049.

Head-to-Head Benchmarks

The recorded head-to-head data covers 11 PassMark tests, with Intel winning all of them. The largest percentage gap is in the find prime numbers test at 81.2%. This test often rewards high core counts and strong integer throughput, and the Intel chip's 16 cores versus 6 cores explains much of the margin.

Floating point math shows Intel at 98,796, AMD at 42,248, a 57.2% deficit for AMD. This is the second-largest gap in the set. The physics test shows a similar pattern: Intel 2,254, AMD 1,022, a 54.7% gap. Data encryption reveals a 51.1% deficit, with Intel at 23,395 and AMD at 11,444. These three tests all show Intel more than doubling the AMD score.

The extended instructions test has Intel at 23,755 versus AMD at 16,520, a 30.5% gap. Random string sorting shows Intel at 36,058 versus AMD at 25,181, a 30.2% gap. The multi-thread test shows Intel at 30,703 versus AMD at 19,262, a 37.3% gap. These mid-range gaps still represent substantial performance differences, but they are not as extreme as the floating-point and prime-number results.

Data compression shows Intel at 298,850 versus AMD at 230,437, a 22.9% gap. Integer math has Intel at 77,975 versus AMD at 62,249, a 20.2% gap. The two single-thread tests (listed as passmark_single_thread and passmark_singlethread, both with identical scores) show Intel at 4,317 versus AMD at 3,713, a 14% gap. This is the smallest relative difference in the entire comparison.

The average benchmark score for the AMD processor is 37,804, while the Intel processor averages 33,537. This is a notable inversion: the Intel chip wins every head-to-head test, yet its average score across all recorded benchmarks is lower. The explanation lies in the benchmark sets. The AMD processor's average includes PassMark tests only, while the Intel processor's average includes Cinebench R15, R20, R23, and Geekbench results alongside the PassMark tests. Those additional tests, which include scores like 9,240 in Cinebench R23 multi-core and 1,843 in single-core, pull the Intel average down relative to its PassMark performance.

The percentile rankings reflect this split. The AMD processor sits at the 86th percentile among all CPUs, while the Intel processor sits at the 83rd percentile. Despite losing every head-to-head PassMark test, the AMD chip ranks slightly higher in the overall database percentile. This suggests that the AMD processor's average score of 37,804, driven by strong PassMark results, places it higher in the aggregate distribution than the Intel chip's average of 33,537.

Nearest rival data reinforces the positioning. The AMD processor's closest rivals include the Intel Core 5 211E at 37,829 (0.1% difference), the AMD Ryzen AI 5 PRO 435 at 37,762 (0.1% difference), the AMD Ryzen AI 9 HX 370 at 37,904 (0.3% difference), and the Intel Core i9-14901E at 37,911 (0.3% difference). The Intel processor's nearest rivals include the AMD Ryzen 5 240 at 33,542 (no percentage difference), the AMD Ryzen 7 8840HS at 33,667 (0.4% difference), the AMD Ryzen 5 7645HX at 33,668 (0.4% difference), and the Intel Core i5-12600HX at 33,375 (0.5% difference). These patterns show each processor clustering with different performance tiers.

The Verdict

The data points to a clear split between raw benchmark dominance and aggregate ranking. The Intel Core Ultra 7 255H wins every single head-to-head PassMark test recorded in the database. Its 16 cores, larger caches, higher boost clock, and wider memory bandwidth all support this outcome. The AMD Ryzen AI Embedded P132, with 6 cores and 12 threads, cannot match the Intel chip in any measured workload.

The AMD processor does hold a higher percentile rank, 86 versus 83, and a higher average benchmark score, 37,804 versus 33,537. These figures come from different benchmark sets. The AMD average reflects PassMark tests only, while the Intel average includes Cinebench and Geekbench results. A buyer or system designer looking at the aggregate database numbers would see the AMD part ranked higher. A buyer looking at direct head-to-head comparisons would see the Intel part winning every test.

The Intel chip is also the newer release, with a release date in January 2025, while the AMD chip carries a March 2026 release date. Both are listed as active production parts with a 28 watt TDP. Neither has a recorded launch MSRP in the database.

For workloads that match the PassMark test suite, such as compression, encryption, floating-point math, prime-number searches, and physics calculations, the Intel Core Ultra 7 255H is the stronger part by a wide margin. The AMD part's best relative showing is in single-thread and integer tasks, where the gap narrows to 14% and 20.2% respectively, but it still loses. The database records no scenario where the AMD processor wins.

The Intel processor also carries a process node advantage, 3 nm versus 4 nm, and a larger L3 cache, 24 MB versus 4 MB. It supports PCIe Gen 5 with 20 lanes versus Gen 4 with 14 lanes. These architectural differences align with the benchmark outcomes. The AMD processor offers 12 threads from 6 cores, ECC memory support, and a lower boost clock of 4.50 GHz versus 5.10 GHz, but these features do not translate into any recorded benchmark win.
