AMD Ryzen 9 PRO 8945HS vs AMD Ryzen AI Embedded P132 Comparison

The AMD Ryzen 9 PRO 8945HS and the AMD Ryzen AI Embedded P132 are both active mobile processors, but the benchmark data places them in different performance tiers. The Ryzen 9 PRO 8945HS, a Zen 4 part from the 8000 series, holds a significant lead in every recorded head-to-head test, while the Ryzen AI Embedded P132, built on Zen 5 / Zen 5c cores, counters with a lower power envelope and a newer architecture. This analysis breaks down the recorded measurements, architectural differences, and specification gaps between the two.

Head-to-Head Benchmarks

The recorded head-to-head data shows a clean sweep for the AMD Ryzen 9 PRO 8945HS, which wins all 11 benchmark comparisons. The largest margin appears in the random string sorting test, where the 8945HS scores 44,668 against 25,181 for the P132, a delta of 77.4%. This indicates a substantial advantage in memory and cache-bound operations.

In data encryption, the 8945HS records 21,820 versus 11,444, a 90.7% lead. This is one of the most decisive single-test wins. Extended instruction workloads also favor the 8945HS heavily: it scores 27,714 compared to 16,520, a delta of 67.8%. Integer math shows a similar pattern, with 103,390 against 62,249, a 66.1% advantage.

The margin narrows in floating-point math, but the 8945HS still wins by 50.3%, scoring 63,490 versus 42,248. Prime number finding, a test heavily dependent on raw integer and branch performance, shows the 8945HS at 91 versus 57, a 59.6% lead. Data compression follows at 60.1%, with scores of 368,884 and 230,437 respectively.

The closest contest is in single-thread performance. The 8945HS scores 3,920, while the P132 scores 3,713, a delta of just 5.6%. This suggests that while the Zen 5 / Zen 5c cores in the P132 are competitive on a per-core basis, they do not overcome the clock speed and cache advantages of the 8945HS in the recorded data. The multithread test shows a 57.7% lead for the 8945HS, 30,378 versus 19,262, and physics simulation shows a 39.9% edge, 1,430 versus 1,022.

The average benchmark scores reflect this overall dominance. The 8945HS posts an average score of 41,963, placing it in the 88th percentile of all CPUs. Its nearest rivals in the database include the Intel Core i7-14700T with an average score of 41,914 and a delta of 0.1%, and the AMD Ryzen 5 7400 at 42,055 with a delta of -0.2%. The P132, with an average score of 37,804, sits in the 86th percentile. Its nearest rival is the Intel Core 5 211E at 37,829 with a delta of -0.1%, and the AMD Ryzen AI 9 HX 370 at 37,904 with a delta of -0.3%. The 8945HS is therefore not only faster than the P132 but also ranked against a higher tier of competitors in the database.

The Verdict

The data directs a clear choice for users who prioritize raw compute throughput: the AMD Ryzen 9 PRO 8945HS. It wins every recorded benchmark, and its average score of 41,963 places it 11% above the P132's 37,804. The 8945HS is the stronger processor for multi-threaded workloads, with a 57.7% lead in the multithread test and a 66.1% lead in integer math. Its 8 cores and 16 threads, combined with a 5.20 GHz boost clock, deliver results that the P132's 6 cores and 12 threads cannot match in the recorded data.

The AMD Ryzen AI Embedded P132 is not without merit, but its strengths appear in efficiency and integration rather than raw benchmark scores. It runs at a 28 W TDP compared to the 45 W TDP of the 8945HS, and it uses a newer Zen 5 / Zen 5c architecture. The single-thread gap of 5.6% shows that its per-core performance is close, which matters for lightly threaded tasks. However, no benchmark in the database records a win for the P132. For workloads that depend on multi-core scaling, the 8945HS is the only choice according to the data.

Where Each One Wins

The AMD Ryzen 9 PRO 8945HS wins in every measured category. Its largest advantages are in random string sorting (77.4% lead), data encryption (90.7% lead), and extended instructions (67.8% lead). These results point to strong performance in compression, encryption, and SIMD-heavy code. The 16 MB of shared L3 cache, larger than the P132's 4 MB, likely supports these cache-sensitive workloads. The 8945HS also wins the multithread test by 57.7%, confirming its suitability for rendering, compilation, and other parallel tasks.

The AMD Ryzen AI Embedded P132 does not win any recorded benchmark, but its architecture suggests a different use case. The Zen 5 / Zen 5c cores, combined with support for DDR5 and LPDDR5X memory, indicate a focus on embedded systems where power draw and integration matter more than peak performance. The single-thread score of 3,713 is only 5.6% behind the 8945HS, so the P132 can handle everyday responsiveness and lightly threaded applications without a major penalty. Its 28 W TDP makes it a fit for thermally constrained designs, but the database records no performance test where it takes the lead.

Architecture Differences

The two processors come from different generations and microarchitectures. The AMD Ryzen 9 PRO 8945HS uses Zen 4 architecture with the codename Hawk Point, part of the 8000 series. The AMD Ryzen AI Embedded P132 uses Zen 5 / Zen 5c architecture with the codename Gorgon Point. Both are fabricated on a 4 nm process at TSMC, but the P132 is listed as an embedded product with a later release date.

The cache layouts differ significantly. The 8945HS has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The P132 has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and only 4 MB of L3 cache. The larger L3 cache on the 8945HS is a likely factor in its substantial leads in cache-sensitive tests like random string sorting and data compression.

The integrated graphics also differ. The 8945HS uses a Radeon 780M, while the P132 uses a Radeon 840M. Both are integrated solutions, but the database records no graphics benchmarks for either processor. The P132 supports both DDR5 and LPDDR5X memory, while the 8945HS supports DDR5. Both use dual-channel memory buses with a recorded bandwidth of 89.6 GB/s.

Specification Differences

The core and thread counts differ: the Ryzen 9 PRO 8945HS has 8 cores and 16 threads, while the Ryzen AI Embedded P132 has 6 cores and 12 threads. Clock speeds also favor the 8945HS, which has a base clock of 4.00 GHz and a boost clock of 5.20 GHz, compared to the P132's 2.00 GHz base and 4.50 GHz boost.

The TDP is another key difference. The 8945HS is rated at 45 W, while the P132 is rated at 28 W. This reflects the P132's embedded positioning and likely lower sustained power draw. The sockets differ as well: the 8945HS uses AMD Socket FP7, and the P132 uses AMD Socket FP8.

Memory support diverges in one respect. The 8945HS supports DDR5, while the P132 supports both DDR5 and LPDDR5X. Both support ECC memory and use a dual-channel bus with 89.6 GB/s bandwidth. The PCIe configurations differ: the 8945HS has Gen 4 with 20 lanes (CPU only), while the P132 has Gen 4 with 14 lanes (CPU only). The 8945HS is not multiplier unlocked, and neither processor is unlocked. The release dates are also distinct, with the 8945HS released in 2024 and the P132 in 2026.
