AMD Ryzen 5 40 vs AMD Ryzen AI Embedded P132 Comparison

Head-to-Head Benchmarks

The recorded head-to-head data is unambiguous: the AMD Ryzen AI Embedded P132 wins every single benchmark in the comparison set, 11 wins to zero. The magnitude of the victory varies substantially by workload, and the pattern reveals where the architectural gap is widest.

The largest single margin comes in extended instructions, where the P132 scores 16,520 against the Ryzen 5 40's 6,437, a 61% deficit for the older part. That result indicates the P132's newer ISA support provides a massive advantage in workloads that leverage SIMD or specialized instruction sets. Prime number finding shows the steepest relative gap at 64.9%, with scores of 57 versus 20, suggesting the P132's per-core integer throughput is dramatically higher, not just its core count.

Floating point math is another decisive win: 42,248 versus 15,194, a 64% gap. The P132 more than doubles the Ryzen 5 40 in this test, which points to a fundamentally stronger FPU design rather than a simple clock advantage. Physics simulation follows a similar pattern, with the P132 at 1,022 versus 432, a 57.7% deficit for the Ryzen 5 40. This workload typically scales with both core count and memory bandwidth, so the combination of 6 cores versus 4 and a faster memory bus likely explains much of the delta.

Multi-threaded performance shows the P132 at 19,262 versus 9,341, a 51.5% gap. That is a slightly smaller margin than the per-core heavy tests, but still a commanding lead. The P132's 6 cores and 12 threads against the Ryzen 5 40's 4 cores and 8 threads gives it a 50% core advantage, and the benchmark data suggests it converts that into roughly a 2x throughput advantage, indicating the per-core efficiency gains are as important as the core count increase.

Integer math shows a 49.2% deficit for the Ryzen 5 40, with the P132 scoring 62,249 versus 31,598. Data encryption shows a 41.9% gap (11,444 versus 6,646), while data compression is closer at 38.6% (230,437 versus 141,533). Random string sorting shows a 39.9% deficit (25,181 versus 15,124). The narrowest margin is single-thread performance at 33.3%: the P132 scores 3,713 versus 2,477. Even in the P132's weakest relative category, it still leads by a third.

The average benchmark score tells the same story. The Ryzen 5 40 sits at 15,882, placing it in the 70th percentile of all CPUs. The P132 averages 37,804, which puts it in the 86th percentile. That is a 137.9% higher average score for the P132, a massive chasm between two mobile parts.

Looking at the nearest rivals places each chip in context. The Ryzen 5 40's closest competitors are server parts like the AMD EPYC 75F3 (15,859, 0.1% lower), the Intel Core Ultra 5 134U (15,910, 0.2% higher), and the AMD EPYC 9354P (15,826, 0.4% lower). The P132, by contrast, competes with much stronger company: the Intel Core 5 211E (37,829, 0.1% higher), the AMD Ryzen AI 5 PRO 435 (37,762, 0.1% lower), the AMD Ryzen AI 9 HX 370 (37,904, 0.3% higher), and the Intel Core i9-14901E (37,911, 0.3% higher). The two chips are not merely separated by a few percentage points; they occupy entirely different performance tiers.

Architecture Differences

The two processors come from different design generations and manufacturing processes. The AMD Ryzen 5 40 uses the Zen 2 architecture under the Mendocino codename, fabricated on a 6 nm process at TSMC. The P132 uses the Gorgon Point codename with a Zen 5 / Zen 5c hybrid design, built on a 4 nm process, also at TSMC. The process shrink from 6 nm to 4 nm is a meaningful contributor to the P132's efficiency and clock headroom.

Core counts differ: the Ryzen 5 40 has 4 cores and 8 threads, while the P132 has 6 cores and 12 threads. That is a 50% core advantage and a 50% thread advantage for the P132. The cache hierarchy also differs. The Ryzen 5 40 has 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The P132 has 80 KB of L1 per core and 1 MB of L2 per core, with also 4 MB of L3. The larger per-core caches on the P132, combined with the newer architecture, help explain the single-thread benchmark advantage.

Clock speeds tell an interesting story. The Ryzen 5 40 has a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The P132 has a lower base clock of 2.00 GHz but a higher boost clock of 4.50 GHz. The P132's boost advantage of 200 MHz is modest, so the 33.3% single-thread lead cannot come from clocks alone. It must come from the Zen 5 core's superior instructions-per-clock, a data-driven inference from the benchmark results.

Memory support diverges significantly. The Ryzen 5 40 supports LPDDR5 only, dual-channel, with a bandwidth of 88.0 GB/s. The P132 supports both DDR5 and LPDDR5X, dual-channel, with bandwidth of 89.6 GB/s. The bandwidth difference is small, about 1.8%, but the P132's support for DDR5 gives it broader system compatibility. ECC memory is another separator: the Ryzen 5 40 does not support ECC, while the P132 does.

PCIe connectivity differs as well. The Ryzen 5 40 provides PCIe Gen 3 with 4 lanes (CPU only). The P132 provides PCIe Gen 4 with 14 lanes (CPU only). That is both a generation upgrade and a 10-lane increase, which matters for embedded systems that need to attach multiple peripherals or fast storage.

The integrated graphics also differ. The Ryzen 5 40 uses the Radeon 610M, while the P132 uses the Radeon 840M. The 840M is a newer part and, based on the overall platform generation gap, should deliver stronger graphics performance, though no graphics benchmarks are recorded in the database for either chip.

The P132 also carries a larger die in terms of process geometry, though the exact die size is not recorded. The Ryzen 5 40 has a die size of 100 mm². The P132's power envelope is higher: 15 W TDP versus 28 W TDP. That 13 W difference is substantial for mobile and embedded designs, and it is a trade-off against the P132's performance lead.

Sockets differ as well: the Ryzen 5 40 uses AMD Socket FT6, while the P132 uses AMD Socket FP8. They are not socket-compatible, meaning system designs cannot swap between the two without a motherboard change.
