AMD Ryzen 5 8400F vs AMD Ryzen AI Embedded P132 Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen 5 8400F and the AMD Ryzen AI Embedded P132 is overwhelmingly one-sided, though not entirely. The 8400F wins 9 of the 11 recorded head-to-head comparisons, while the P132 wins 2. The wins for the 8400F cover nearly every workload category in the database: multithreaded throughput, integer and floating-point math, data compression and encryption, extended instruction sets, prime number search, physics simulation, and random string sorting. The P132 takes only the single-thread PassMark tests, and by a razor-thin margin.

For desktop users running demanding applications, the 8400F is the clear performer in almost every measurable category. It leads in passmark_multithread by 26.6%, in passmark_integer_math by 18.9%, and in passmark_floating_point_math by 9.4%. The largest gaps appear in passmark_find_prime_numbers (56.1% ahead), passmark_data_encryption (45.5% ahead), and passmark_random_string_sorting (37.4% ahead). These are substantial margins that translate directly into faster completion times for compression, encryption, and numerical workloads.

The P132's single-thread edge is 3713 versus 3685, a 0.8% difference. That is a nominal advantage, not a meaningful one for real-world applications. The P132 does not win any multithreaded test, which matters because its 6-core, 12-thread configuration is identical to the 8400F in core count. The P132's wins are essentially a tie in practice, given the sub-1% delta.

The 8400F also posts a higher percentileVsAllCpus of 77, while the P132 sits at 86. However, the average benchmark score tells a different story: the P132 averages 37804 across its recorded benchmarks, versus 25005 for the 8400F. That discrepancy reflects the different benchmark suites recorded for each processor, not a direct performance comparison, since the head-to-head table is the authoritative source for direct comparisons.

Architecture Differences

The two processors share the same manufacturer, process node, and foundry, but diverge sharply in nearly every other architectural detail. Both use 4 nm TSMC fabrication, but the 8400F is built on Zen 4 with the codename Phoenix, while the P132 uses a Gorgon Point codename with a Zen 5 / Zen 5c generation label. The 8400F belongs to the 8000 series, has a Desktop market segment, and uses AMD Socket AM5. The P132 is a Mobile part, uses AMD Socket FP8, and carries no series designation.

Core and thread counts match: 6 cores and 12 threads on both. Clock speeds differ substantially. The 8400F has a 4.20 GHz base clock and a 4.70 GHz boost clock, while the P132 runs at 2.00 GHz base and 4.50 GHz boost. The 8400F's higher base clock is a large advantage for sustained workloads, while the boost gap is smaller at 0.20 GHz.

Cache configurations are notably different. The 8400F provides 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The P132 provides 80 KB L1 per core, 1 MB L2 per core, but only 4 MB of L3. That 12 MB L3 deficit is significant for workloads that rely on large working sets fitting in cache. The 8400F also has a larger die at 178 mm² and 25,000 million transistors, while the P132 lists no die size or transistor count in the database.

Memory support differs as well. The 8400F supports DDR5 only, with dual-channel memory and 83.2 GB/s bandwidth. The P132 supports both DDR5 and LPDDR5X, also dual-channel, with a higher 89.6 GB/s bandwidth. ECC memory is supported on the P132 but not on the 8400F. PCIe lane counts diverge: the 8400F has Gen 4 with 20 lanes (CPU only), while the P132 has Gen 4 with 14 lanes. The P132 includes integrated graphics (Radeon 840M), while the 8400F has no iGPU. The 8400F has an unlocked multiplier; the P132 does not.

Head-to-Head Benchmarks

The direct comparison table shows the 8400F winning every multithreaded and math-heavy test. Starting with passmark_data_compression, the 8400F scores 288158 against 230437, a 25% lead. The encryption test shows a larger gap: 16646 versus 11444, a 45.5% advantage. Extended instruction performance follows the same pattern: 22175 versus 16520, a 34.2% lead.

Prime number finding is the most lopsided result. The 8400F scores 89, the P132 scores 57, a 56.1% difference. Floating-point math is closer: 46217 against 42248, a 9.4% edge. Integer math shows a clear 18.9% lead with 74021 versus 62249. The multithread PassMark result is 24389 against 19262, a 26.6% margin.

Physics simulation favors the 8400F at 1332 versus 1022, a 30.3% lead. Random string sorting goes to the 8400F as well: 34604 versus 25181, a 37.4% margin. The only two P132 wins are the single-thread PassMark tests, both recording 3713 against 3685, a 0.8% difference. Those two identical scores appear as separate entries in the head-to-head table but represent the same test measured twice.

The overall win count is 9 for the 8400F and 2 for the P132. The magnitude of the 8400F's wins ranges from 9.4% to 56.1%, while the P132's wins stay below 1%. That asymmetry is important: the 8400F does not just win more tests, it wins them by much larger margins than the P132's narrow single-thread advantage.

The Verdict

The data presents a clear separation of roles. The AMD Ryzen 5 8400F is a desktop processor with a 65 W TDP, a 4.20 GHz base clock, an unlocked multiplier, and a large 16 MB L3 cache. It wins 9 of the 11 head-to-head benchmarks, with margins ranging from 9.4% to 56.1%. Its multithreaded lead of 26.6% in PassMark, combined with strong results in integer math, floating-point math, compression, and encryption, makes it the choice for workloads that push all cores and rely on cache capacity.

The AMD Ryzen AI Embedded P132 is a mobile processor with a 28 W TDP, a 2.00 GHz base clock, a locked multiplier, and only 4 MB L3. It supports ECC memory and LPDDR5X, includes Radeon 840M integrated graphics, and its only benchmark wins are two single-thread PassMark results at 0.8% ahead. For applications that need sustained all-core performance, the 8400F wins decisively. For embedded or mobile systems where power efficiency, ECC support, and integrated graphics matter more than raw multithreaded output, the P132 has a purpose, but the benchmark data does not show it outperforming the 8400F in any meaningful computational category.

The percentile ranking favors the P132 at 86 versus 77, but the average benchmark score for the P132 (37804) versus the 8400F (25005) reflects different benchmark suites, not comparable performance. The direct head-to-head table is the only valid comparison, and it favors the 8400F in nearly every test.
