AMD Ryzen 7 8745HX vs AMD Ryzen AI Embedded P132 Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive sweep: the AMD Ryzen 7 8745HX wins all 11 recorded head-to-head comparisons, with the AMD Ryzen AI Embedded P132 failing to take a single test. The margin, however, is far from uniform, and the distribution of those deltas tells a more nuanced story than the raw win count suggests.

The largest gap appears in `passmark_find_prime_numbers`, where the 8745HX scores 159 against the P132's 57, a massive 178.9% advantage. This workload is highly sensitive to core count, clock speed, and instruction efficiency, and the 8745HX's 8 cores and 16 threads, running at a 5.10 GHz boost, simply overwhelm the P132's 6 cores and 12 threads with a 4.50 GHz boost. The prime-number sieve is a classic integer-heavy, branch-predictor-stressing test, and the data indicates a fundamental throughput disparity.

The second-largest delta is in `passmark_data_encryption`, where the 8745HX posts 21,840 versus 11,444, a 90.8% lead. Encryption algorithms often rely on large data blocks and parallel operations, favoring the higher core count and the 32 MB of shared L3 cache on the 8745HX. The P132's much smaller 4 MB L3 cache likely creates a bottleneck here, forcing more frequent memory fetches. The 8745HX also has a higher memory bandwidth figure of 83.2 GB/s, though the P132 actually lists a higher 89.6 GB/s, so the cache hierarchy, not raw bandwidth, appears to be the differentiator in this test.

`passmark_random_string_sorting` shows a 76.7% win for the 8745HX (44,494 vs. 25,181). String sorting is memory-latency-sensitive and benefits from large caches and high memory parallelism. The 8745HX's 32 MB L3 versus the P132's 4 MB L3 is a stark contrast, and the data suggests this cache size gap directly translates into the observed performance delta.

Moving toward more general workloads, `passmark_multithread` gives the 8745HX a 63.6% advantage (31,517 vs. 19,262). This is a broad measure of parallel processing capability, and the 33% core advantage (8 vs. 6) combined with the higher boost clock explains a large portion of the gap. The `passmark_physics` test shows a 64.5% lead (1,681 vs. 1,022), which often involves floating-point vector operations and multi-body simulations, again favoring the larger core pool.

`passmark_integer_math` shows a 61.2% delta (100,328 vs. 62,249), and `passmark_floating_point_math` shows a 46.7% delta (61,972 vs. 42,248). Both tests reflect the raw arithmetic throughput of the cores, and the 8745HX's Zen 4 architecture, running at a higher clock, delivers consistently higher results. The `passmark_extended_instructions` test, which exercises newer x86 instruction set extensions, shows a 67.3% lead (27,638 vs. 16,520), suggesting the 8745HX's implementation is more efficient for these workloads.

The `passmark_data_compression` test shows a 57.9% delta (363,759 vs. 230,437), a smaller margin than the encryption test but still a clear victory. Compression algorithms often use a mix of integer, memory, and branch operations, and the 8745HX's overall higher scores in each of those sub-tests aggregate into this result.

Finally, the closest contest is in `passmark_single_thread` (and the duplicate `passmark_singlethread` entry), where the 8745HX wins by a slim 4.5% (3,879 vs. 3,713). This is the only test where the P132 comes within striking distance. The P132's Zen 5 / Zen 5c architecture, despite having a lower boost clock of 4.50 GHz versus 5.10 GHz, manages to nearly match the 8745HX's single-core performance. This indicates that the P132's newer core design is significantly more efficient per clock, but the 8745HX's raw clock advantage still wins the day. This single-thread result is a critical data point, as it shows the P132's architectural potential is real, but it is not enough to overcome the 8745HX's clock speed and core count in any benchmark.

Architecture Differences

The two processors diverge sharply in their underlying designs. The AMD Ryzen 7 8745HX is built on the Zen 4 architecture, codenamed Dragon Range, and belongs to the 8000 series. The AMD Ryzen AI Embedded P132 uses a newer Zen 5 / Zen 5c design, codenamed Gorgon Point, and is part of the Ryzen AI Embedded line. This generational split is immediately visible in the process node: the 8745HX uses a 5 nm process, while the P132 uses a smaller 4 nm process, both fabricated by TSMC. The smaller node on the P132 typically enables higher transistor density and lower power draw, which is consistent with its much lower TDP of 28 watts versus the 8745HX's 55 watts.

Core and cache configurations differ fundamentally. The 8745HX offers 8 cores and 16 threads, with 64 KB L1 per core and 1 MB L2 per core. Its L3 cache is a substantial 32 MB shared pool. The P132 offers 6 cores and 12 threads, with a larger L1 cache of 80 KB per core and the same 1 MB L2 per core, but its L3 cache is only 4 MB. This is a 8x difference in shared cache, which directly explains the 8745HX's strong performance in cache-sensitive workloads like encryption and string sorting. The P132's larger L1 per core suggests its designers prioritized per-core latency, but the small L3 limits cross-core data sharing.

Memory support also differs. The 8745HX supports only DDR5, while the P132 supports both DDR5 and LPDDR5X. Both are dual-channel, but the P132 lists a slightly higher memory bandwidth of 89.6 GB/s versus 83.2 GB/s. The P132 also supports ECC memory, a feature absent on the 8745HX, which is a notable advantage for embedded and reliability-focused applications.

PCIe connectivity is another differentiator. The 8745HX provides Gen 5 with 28 lanes (CPU only), while the P132 provides Gen 4 with 14 lanes (CPU only). This means the 8745HX offers twice the lane count and a newer PCIe generation, which is significant for high-throughput add-on cards, GPUs, or NVMe storage. The 8745HX also has an unlocked multiplier, allowing overclocking, while the P132 is locked.

The integrated graphics differ as well: the 8745HX uses a Radeon 610M, while the P132 uses a Radeon 840M. The P132's newer Radeon 840M likely supports more modern display outputs and codecs, though the benchmark data does not include graphics tests. The 8745HX uses the AMD Socket FL1, while the P132 uses the AMD Socket FP8, indicating they are not socket-compatible.

Finally, the 8745HX has a known transistor count of 6,570 million on a 71 mm² die, while the P132's transistor count and die size are not recorded in the database. The 8745HX was released on 2025-04-22, while the P132 is dated later, 2026-03-08. Neither has a recorded launch MSRP.

The Verdict

The benchmark data is unambiguous: the AMD Ryzen 7 8745HX is the superior performer in every recorded test. It holds an 11-0 win record against the AMD Ryzen AI Embedded P132, with average benchmark scores of 60,104 versus 37,804, a 59% overall difference. The 8745HX's 92nd percentile ranking versus the P132's 86th percentile confirms its higher standing in the broader CPU population.

The 8745HX delivers its wins through raw resources: more cores (8 vs. 6), higher boost clock (5.10 vs. 4.50 GHz), and a vastly larger L3 cache (32 MB vs. 4 MB). These advantages translate into decisive victories in multi-threaded and cache-heavy workloads, with deltas ranging from 46.7% to 178.9%. The only close contest is single-thread performance, where the 8745HX wins by just 4.5%, showing that the P132's newer Zen 5 core design is competitive on a per-clock basis.

The P132, however, is not without its own merits. It offers ECC memory support, a lower TDP of 28 watts, a smaller 4 nm process node, and support for LPDDR5X memory. It also has a higher memory bandwidth figure (89.6 GB/s vs. 83.2 GB/s) and a more recent integrated GPU (Radeon 840M vs. Radeon 610M). For applications where power efficiency, reliability features, or low-power operation are critical, the P132 may be the more appropriate choice. But for pure computational performance, the data clearly favors the 8745HX.

Where Each One Wins

The AMD Ryzen 7 8745HX wins in all performance-centric use cases. Its 178.9% lead in prime-number finding and 90.8% lead in data encryption make it the clear choice for scientific computing, cryptographic workloads, and any application that stresses integer arithmetic and large caches. Its 63.6% lead in multithreaded performance and 64.5% lead in physics simulations position it well for rendering, simulation, and heavy parallel processing. The 8745HX also wins in floating-point math (46.7% lead), integer math (61.2% lead), and extended instructions (67.3% lead), covering a broad spectrum of computational tasks. Its 57.9% lead in data compression and 76.7% lead in random string sorting round out its dominance in data-intensive operations. Users running demanding desktop or mobile workstation tasks, where power draw of 55 watts is acceptable, will find the 8745HX delivers superior results.

The AMD Ryzen AI Embedded P132 wins in none of the recorded benchmarks, but its specification sheet suggests specific strengths outside those tests. Its ECC memory support makes it suitable for embedded systems requiring data integrity, such as industrial control, networking appliances, or edge servers where a bit-flip can be catastrophic. Its lower 28-watt TDP and 4 nm process node indicate higher power efficiency, which is critical for fanless or battery-powered designs. The support for LPDDR5X memory allows for lower-power memory configurations. The 4.5% single-thread deficit, while a loss, is small enough that the P132 remains competitive in lightly-threaded, latency-sensitive applications. Its Radeon 840M integrated graphics may also be newer and more capable than the 8745HX's Radeon 610M, though no graphics benchmarks are recorded. The P132 is the choice for embedded, low-power, or reliability-focused deployments, while the 8745HX is the choice for raw performance.
