AMD Ryzen 9 7940HX vs AMD Ryzen AI Embedded P132 Comparison

AMD Ryzen 9 7940HX and AMD Ryzen AI Embedded P132 occupy different tiers of the mobile processor spectrum. The Ryzen 9 7940HX is a 16-core, 32-thread Dragon Range part built on Zen 4, while the Ryzen AI Embedded P132 is a 6-core, 12-thread Gorgon Point part using Zen 5 and Zen 5c. In the database, the 7940HX wins all 11 head-to-head benchmark comparisons, with an average benchmark score of 69875 against 37804 for the P132. The 7940HX sits at the 94th percentile of all CPUs, while the P132 sits at the 86th percentile.

Where Each One Wins

The benchmark results indicate a complete sweep for the AMD Ryzen 9 7940HX across all 11 recorded comparisons. There is no workload category in the data where the Ryzen AI Embedded P132 takes the lead. The 7940HX dominates in multi-threaded tasks, with its largest advantages appearing in compute-heavy integer and prime-number operations. The passmark_multithread score of 53204 for the 7940HX versus 19262 for the P132 reflects a 176.2% difference, meaning the 7940HX delivers roughly 2.76 times the throughput in fully threaded workloads.

The P132 does not win any of the 11 head-to-head tests, but its closest showing is in passmark_single_thread, where it trails by only 6.2%. The 7940HX records 3942 points in single-threaded tests, while the P132 records 3713 points. This narrow margin indicates that the newer Zen 5 architecture in the P132 narrows the per-core gap substantially, even though it cannot overcome the 16-core versus 6-core core count disadvantage. In content-creation tasks such as data compression and encryption, the 7940HX leads by 201.1% and 266.8% respectively, confirming that the embedded part is not positioned for heavy parallel throughput.

For workloads that stress floating-point math, the 7940HX scores 121383 against 42248 for the P132, a 187.3% advantage. The P132 is a lower-power part with a 28 W TDP, so its role is likely constrained to efficiency-focused embedded scenarios. The data shows no scenario where the P132 is the recommended choice on raw performance; its appeal rests on different characteristics such as ECC memory support and a smaller physical footprint.

Architecture Differences

The two processors differ fundamentally in their design goals. The AMD Ryzen 9 7940HX uses the Zen 4 architecture with the Dragon Range codename, built on a 5 nm process at TSMC. It integrates 13,140 million transistors across a dual-die design with each die measuring 71 mm². The Ryzen AI Embedded P132 uses the Zen 5 and Zen 5c hybrid architecture with the Gorgon Point codename, built on a 4 nm process at TSMC. The P132 has no listed transistor count or die size in the database.

Core configurations diverge sharply. The 7940HX has 16 cores and 32 threads with a base clock of 2.40 GHz and a boost clock of 5.20 GHz. The P132 has 6 cores and 12 threads with a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The 7940HX has an unlocked multiplier, allowing overclocking, while the P132 has a locked multiplier. Cache hierarchies also differ: the 7940HX provides 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. The P132 provides 80 KB of L1 per core, 1 MB of L2 per core, but only 4 MB of L3 cache. The L3 difference of 60 MB is substantial and contributes to the 7940HX's advantage in repeated data access patterns.

Memory support separates the two parts. The 7940HX supports DDR5 only, with a dual-channel bus and 83.2 GB/s of memory bandwidth. The P132 supports both DDR5 and LPDDR5X, also with a dual-channel bus, but reaches 89.6 GB/s of memory bandwidth. The P132 supports ECC memory, while the 7940HX does not. PCIe connectivity also differs: the 7940HX provides Gen 5 with 28 lanes, while the P132 provides Gen 4 with 14 lanes. The integrated graphics differ as well, with the 7940HX using Radeon 610M and the P132 using Radeon 840M.

The release dates show a generational gap. The 7940HX launched on 2024-01-16 and belongs to the 7000 series. The P132 launched on 2026-03-08 and belongs to the Ryzen AI Embedded line. Both parts are currently marked as active in production. The 7940HX uses the AMD Socket FL1, while the P132 uses the AMD Socket FP8.

Head-to-Head Benchmarks

The largest single advantage for the 7940HX appears in passmark_find_prime_numbers, where it scores 273 against 57, a 378.9% delta. This test is highly sensitive to core count and integer execution resources, so the 16-core part overwhelms the 6-core part. The next largest gap is in passmark_data_encryption at 266.8%, with scores of 41974 and 11444. The 7940HX also leads passmark_integer_math by 225.9%, scoring 202883 versus 62249. In passmark_random_string_sorting, the delta is 224.7%, with scores of 81775 and 25181.

The passmark_extended_instructions test shows a 208.9% advantage for the 7940HX, with scores of 51029 and 16520. Data compression follows at 201.1%, with scores of 693741 and 230437. Floating-point math shows a 187.3% delta, with scores of 121383 and 42248. The passmark_multithread test shows a 176.2% delta, with scores of 53204 and 19262. The physics test shows a 124.8% delta, with scores of 2297 and 1022. The smallest margin is in passmark_single_thread, where the 7940HX leads by just 6.2% with scores of 3942 and 3713.

These deltas are consistent across the board. The 7940HX does not merely edge out the P132 in most tests; it more than doubles the P132's score in 9 of the 11 comparisons. The only tests where the margin falls below 100% are physics at 124.8% and single-thread at 6.2%. The single-thread result is particularly informative: the P132's Zen 5-based cores nearly match the Zen 4 cores of the 7940HX on a per-thread basis, but the P132 lacks the core count to compete in any multi-threaded scenario.

In the context of its nearest rivals, the 7940HX sits within a tight band. Its average benchmark score of 69875 is 0.2% below the AMD Ryzen 7 9700F (69996), 0.4% below the Intel Core i7-14700KF (70163), 0.5% above the AMD Ryzen 9 7950X (69515), and 0.7% above the Intel Core i7-14700K (69355). The P132 also has close rivals: it is 0.1% below the Intel Core 5 211E (37829), 0.1% above the AMD Ryzen AI 5 PRO 435 (37762), 0.3% below the AMD Ryzen AI 9 HX 370 (37904), and 0.3% below the Intel Core i9-14901E (37911). The P132's average score of 37804 places it just 0.1% below the Intel Core 5 211E, indicating that it is not an outlier in its own performance class.

The Verdict

The data is unambiguous. The AMD Ryzen 9 7940HX is the superior processor for any workload that benefits from high core counts, large L3 cache, or higher boost clocks. Its 16 cores, 32 threads, 64 MB of L3 cache, and 5.20 GHz boost clock give it an overwhelming advantage in multi-threaded benchmarks. The P132 cannot compete on raw performance, losing every head-to-head comparison and posting an average benchmark score that is 45.9% lower than the 7940HX (37804 versus 69875).

The Ryzen AI Embedded P132 offers different strengths that are not captured in the benchmark scores. It supports ECC memory, which the 7940HX does not, and it uses a newer 4 nm process with a hybrid Zen 5 and Zen 5c core design. Its 28 W TDP is significantly lower than the 7940HX's 55 W TDP, and its 89.6 GB/s memory bandwidth is slightly higher than the 7940HX's 83.2 GB/s. The P132 also supports LPDDR5X memory, which can be relevant for compact embedded designs. However, the P132 is a locked multiplier part with only 4 MB of L3 cache and 14 PCIe Gen 4 lanes, so it is not positioned for high-end compute.

From a purely performance standpoint, the 7940HX is the clear pick for multi-threaded mobile workloads. The P132 is better suited for embedded deployments that require ECC memory, lower power draw, or LPDDR5X support. The single-thread margin of 6.2% shows that the P132's architecture is competitive per core, but the 176.2% multithread delta and the 378.9% prime-number delta confirm that core count and cache size dominate the overall comparison.
