AMD Ryzen 7 8840HX vs AMD Ryzen AI Embedded P132 Comparison

The Verdict

The recorded data positions the AMD Ryzen 7 8840HX as the dominant processor across every benchmark in the comparison set. It wins all 11 head-to-head tests, with margins ranging from 6.6% in single-threaded workloads to 433.3% in prime number finding. The Ryzen AI Embedded P132 does not secure a single victory, which makes the performance hierarchy unambiguous.

The Ryzen 7 8840HX sits in the 94th percentile of all CPUs in the database, while the Ryzen AI Embedded P132 lands in the 86th percentile. The average benchmark score for the 8840HX is 71,797, compared to 37,804 for the P132. The nearest rival data reinforces this gap: the 8840HX trades within 0.8% of Intel Xeon 6724P, Intel Xeon 6517P, Intel Core Ultra 7 265KF, and Intel Xeon Platinum 8270. The P132 competes against a lower tier, including AMD Ryzen AI 5 PRO 435 and Intel Core 5 211E, with deltas under 0.3%.

The data indicates the 8840HX is the choice for workloads that demand maximum multi-threaded throughput, heavy integer math, or encryption processing. The P132, with its lower core count and smaller cache, serves scenarios where the 28 W TDP and embedded feature set matter more than raw performance. The P132 includes ECC memory support, a feature absent on the 8840HX, which can be decisive for reliability-focused embedded deployments.

Architecture Differences

The two processors come from different design lineages. The Ryzen 7 8840HX uses the Zen 4 architecture on the Dragon Range codename, fabricated on TSMC's 5 nm process. The Ryzen AI Embedded P132 uses a Zen 5 / Zen 5c hybrid configuration under the Gorgon Point codename, built on TSMC's 4 nm node.

Core counts differ substantially. The 8840HX provides 12 cores and 24 threads, while the P132 offers 6 cores and 12 threads. Clock speeds favor the 8840HX: 2.90 GHz base and 5.10 GHz boost versus 2.00 GHz base and 4.50 GHz boost for the P132.

Cache hierarchies diverge sharply. The 8840HX allocates 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3. The P132 uses 80 KB of L1 per core, 1 MB of L2 per core, but only 4 MB of L3. The 8840HX holds a 16x advantage in L3 capacity, which directly explains its superiority in data-heavy workloads.

The 8840HX reports 13,140 million transistors across a dual-die design measuring 2x 71 mm². The P132 has no transistor count or die size recorded in the database. Both processors use TSMC as the foundry.

The 8840HX carries 28 PCIe Gen 5 lanes, while the P132 provides 14 PCIe Gen 4 lanes. Memory support favors the P132 for flexibility: it accepts both DDR5 and LPDDR5X, whereas the 8840HX supports only DDR5. Memory bandwidth slightly favors the P132 at 89.6 GB/s versus 83.2 GB/s. ECC memory is supported only on the P132.

Socket types differ: the 8840HX uses AMD Socket FL1, and the P132 uses AMD Socket FP8. The 8840HX has an unlocked multiplier; the P132 does not. Integrated graphics differ, with the 8840HX featuring Radeon 610M and the P132 using Radeon 840M.

The release dates place the 8840HX in April 2025 and the P132 in March 2026, making the P132 the newer design despite its lower performance profile.

Where Each One Wins

The Ryzen 7 8840HX wins every measured benchmark category. Its largest advantage appears in passmark_find_prime_numbers, where it scores 304 versus 57, a delta of 433.3%. This workload stresses branch prediction and integer arithmetic, areas where the 8840HX's larger cache and higher boost clock provide clear benefit.

Data encryption shows a 161.4% advantage, with scores of 29,919 versus 11,444. Integer math follows at 135.4%, with 146,506 versus 62,249. Random string sorting delivers a 130.2% edge, scoring 57,971 versus 25,181. Extended instructions show a 121.1% gap, at 36,527 versus 16,520.

Multi-threaded performance favors the 8840HX by 116.7%, with 41,732 versus 19,262. Data compression shows a 115.4% advantage, at 496,427 versus 230,437. Physics simulation records a 113.8% edge, at 2,185 versus 1,022. Floating point math completes the list of large gaps at 105.3%, with 86,747 versus 42,248.

The narrowest margin is single-thread performance. The 8840HX scores 3,958 versus 3,713 for the P132, a 6.6% delta. This indicates that per-core efficiency is closer between the two, even though the 8840HX still leads.

The P132 wins no category. Its only compensatory attributes are architectural, not performance-based: ECC memory, lower TDP, and support for LPDDR5X. The data does not show any benchmark where the P132 outperforms the 8840HX.

Head-to-Head Benchmarks

The largest victory for the 8840HX comes in passmark_find_prime_numbers. The 8840HX scores 304 against 57 for the P132, a 433.3% delta. This workload is highly sensitive to clock speed and cache latency, both of which favor the 8840HX.

Data encryption shows the second-largest gap. The 8840HX records 29,919 versus 11,444, a 161.4% advantage. Encryption routines benefit from the 8840HX's larger L3 cache and higher boost clock, which reduce memory stalls during repeated key operations.

Integer math follows at 135.4%. The 8840HX scores 146,506, while the P132 manages 62,249. Random string sorting delivers a 130.2% edge, with 57,971 versus 25,181. Extended instructions show a 121.1% gap, at 36,527 versus 16,520.

Multi-threaded performance, measured by passmark_multithread, shows a 116.7% advantage. The 8840HX achieves 41,732, and the P132 reaches 19,262. The 12-core versus 6-core count directly explains this result. Data compression follows at 115.4%, with 496,427 versus 230,437.

Physics simulation records a 113.8% edge, at 2,185 versus 1,022. Floating point math completes the large-margin set at 105.3%, with 86,747 versus 42,248. Each of these workloads relies on either high thread counts or substantial cache capacity, both of which the 8840HX provides in greater measure.

The single-thread tests, passmark_single_thread and passmark_singlethread, both produce identical results: 3,958 for the 8840HX and 3,713 for the P132, a 6.6% delta. This narrow margin shows that the architectural improvements in the P132's Zen 5 design partially close the per-core gap, but not enough to overcome the 8840HX's higher boost clock.

The 8840HX leads in 11 of 11 head-to-head benchmarks. The P132 has zero wins. The data provides no scenario in the measured set where the P132 outperforms the 8840HX.
