AMD Ryzen 5 40 vs AMD Ryzen AI Embedded P132i Comparison

The Verdict

The AMD Ryzen 5 40 is the only one of these two processors with recorded benchmark results. The AMD Ryzen AI Embedded P132i has no benchmark entries in the database, so its performance cannot be quantified. Based strictly on the data, the Ryzen 5 40 sits at the 70th percentile among all CPUs, with an average benchmark score of 15882. Its nearest rivals in the database are the AMD EPYC 75F3 at 15859 (0.1% behind), the Intel Core Ultra 5 134U at 15910 (0.2% ahead), the AMD EPYC 9354P at 15826 (0.4% behind), and the AMD EPYC 9334 at 15940 (0.4% ahead). This places the Ryzen 5 40 squarely in a cluster of high-performance server and mobile parts, despite its modest 4-core configuration.

The Ryzen 5 40 is the only chip here that can be analyzed for performance. It delivers a Cinebench R23 multi-core score of 4841 and a single-core score of 1150. In PassMark, it scores 9341 in multi-thread, 2477 in single-thread, and 31598 in integer math. These numbers indicate a part that handles everyday workloads and moderately threaded tasks competently. The P132i, by contrast, has no measured data, so any purchase decision involving it would be made without benchmark evidence in this database.

The P132i does offer structural advantages on paper: 6 cores, 12 threads, a 4 nm process node, Zen 5 / Zen 5c architecture, DDR5 and LPDDR5X memory support, ECC memory, 14 PCIe Gen 4 lanes, and a Radeon 840M integrated GPU. The Ryzen 5 40 has 4 cores, 8 threads, a 6 nm node, Zen 2 architecture, LPDDR5 memory only, no ECC, 4 PCIe Gen 3 lanes, and a Radeon 610M GPU. However, none of these advantages can be validated with benchmark scores. The data only shows that the Ryzen 5 40 performs at a level comparable to much larger server CPUs in the database, while the P132i remains untested.

Architecture Differences

The Ryzen 5 40 uses the Zen 2 architecture on the Mendocino codename, manufactured on a 6 nm process at TSMC. The P132i uses the Zen 5 / Zen 5c architecture on the Gorgon Point codename, manufactured on a 4 nm process at TSMC. The process node difference is significant: 6 nm versus 4 nm. The P132i is therefore built on a denser, more modern manufacturing process. The Ryzen 5 40 has a die size of 100 mm², while the P132i has no die size recorded.

The Ryzen 5 40 has 4 cores and 8 threads. The P132i has 6 cores and 12 threads. Cache layouts differ as well. The Ryzen 5 40 has 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The P132i has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3. The P132i offers more per-core cache in both L1 and L2.

Memory support is another clear split. The Ryzen 5 40 supports only LPDDR5 in a dual-channel configuration, with 88.0 GB/s of memory bandwidth. The P132i supports DDR5 and LPDDR5X, also dual-channel, with 89.6 GB/s of memory bandwidth. The P132i also supports ECC memory, while the Ryzen 5 40 does not.

PCIe connectivity differs substantially. The Ryzen 5 40 provides PCIe Gen 3 with 4 lanes (CPU only). The P132i provides PCIe Gen 4 with 14 lanes (CPU only). That is both a newer generation and more lanes. The integrated graphics differ too: the Ryzen 5 40 has a Radeon 610M, while the P132i has a Radeon 840M. Both are mobile market parts, but the P132i targets the embedded segment with its "Ryzen AI Embedded" branding.

Clock speeds also diverge. The Ryzen 5 40 has a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The P132i has a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The P132i starts lower but boosts higher. Thermal design power differs as well: the Ryzen 5 40 is rated at 15 W, while the P132i is rated at 28 W.

Socket and release dates are different. The Ryzen 5 40 uses AMD Socket FT6, while the P132i uses AMD Socket FP8. The Ryzen 5 40 has a release date of 2025-09-30, and the P132i has a release date of 2026-03-08. Neither processor has an unlocked multiplier. Neither has a recorded launch MSRP.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two processors. The AMD Ryzen AI Embedded P132i has zero recorded benchmark scores across every test category. The AMD Ryzen 5 40 has 15 recorded scores, which means all measurable performance data in this comparison belongs to one side.

The Ryzen 5 40 records a Cinebench R23 multi-core score of 4841 and a single-core score of 1150. In Cinebench R15, it scores 790 multi-core and 165.5 single-core. In PassMark tests, the Ryzen 5 40 scores 9341 in multi-thread, 2477 in single-thread, 31598 in integer math, 15194 in floating point math, 141533 in data compression, 6646 in data encryption, 6437 in extended instructions, 20 in find prime numbers, 432 in physics, and 15124 in random string sorting.

Because the P132i has no scores, the database cannot show any wins for it. The wins for the Ryzen 5 40 are effectively all tests where it has a recorded score and the P132i has none. That is every single benchmark in the database. The Ryzen 5 40 also sits at the 70th percentile among all CPUs, while the P132i sits at the 50th percentile, though that percentile for the P132i comes with an average score of 0, indicating no supporting data.

The nearest rivals for the Ryzen 5 40 provide context for its performance. Its average score of 15882 is 0.1% above the AMD EPYC 75F3 (15859), 0.4% above the AMD EPYC 9354P (15826), 0.2% below the Intel Core Ultra 5 134U (15910), and 0.4% below the AMD EPYC 9334 (15940). These are extremely tight margins, all within 0.4% of each other. The Ryzen 5 40, a 4-core mobile chip, effectively matches the average performance of enterprise server processors in this database. The P132i cannot be placed in any comparable ranking because it has no measured average score.

Where Each One Wins

The AMD Ryzen 5 40 wins in every category where actual performance data exists. It has recorded benchmark scores in Cinebench R15, Cinebench R23, and PassMark suites covering multi-thread, single-thread, integer math, floating point math, data compression, data encryption, extended instructions, prime number finding, physics, and random string sorting. Its 70th percentile ranking and average score of 15882 give it a measurable position in the database. It also wins on base clock (2.80 GHz versus 2.00 GHz) and on TDP efficiency, drawing 15 W versus 28 W.

The AMD Ryzen AI Embedded P132i wins on paper specifications that have no benchmark confirmation. It has more cores (6 versus 4), more threads (12 versus 8), a higher boost clock (4.50 GHz versus 4.30 GHz), a smaller process node (4 nm versus 6 nm), a newer architecture (Zen 5 / Zen 5c versus Zen 2), more per-core L1 and L2 cache, support for DDR5 and LPDDR5X memory, ECC memory support, higher memory bandwidth (89.6 GB/s versus 88.0 GB/s), more PCIe lanes (14 versus 4) on a newer generation (Gen 4 versus Gen 3), and a newer integrated GPU (Radeon 840M versus Radeon 610M). Its release date is later, 2026-03-08 versus 2025-09-30.

The practical split is simple. For any use case requiring measured performance, the Ryzen 5 40 is the only option with data. For use cases requiring ECC memory, more PCIe lanes, or a newer architecture, the P132i offers those features on its spec sheet, but the database cannot confirm their real-world impact. The 50th percentile ranking for the P132i, paired with a zero average score, indicates the absence of test results rather than a measured performance level.
