AMD Ryzen 5 40 vs AMD Ryzen AI Embedded P174i Comparison

The Verdict

The recorded data separates these two AMD mobile processors into distinct roles. The AMD Ryzen 5 40 is a complete, measured product with a full benchmark suite, landing in the 70th percentile of all CPUs in the database. The AMD Ryzen AI Embedded P174i has no recorded benchmark scores, an average score of zero, and sits in the 50th percentile based on its specifications alone. The Ryzen 5 40 is for workloads where verified performance matters now; the P174i is for embedded designs that prioritize I/O capacity, ECC memory, and a higher boost clock on paper.

The Ryzen 5 40 delivers a Cinebench R23 multi-core score of 4841 and a single-core score of 1150. Its PassMark multi-thread score of 9341 places it near the AMD EPYC 75F3 (average score 15859, delta 0.1%) and Intel Core Ultra 5 134U (average score 15910, delta -0.2%) in overall average benchmark score. The P174i cannot be compared on measured performance because the database contains no benchmark entries for it. The verdict from the data: choose the Ryzen 5 40 for any task requiring quantified compute results; choose the P174i only when the design requires its specific embedded features, accepting that its performance is unverified.

The P174i has a 5.00 GHz boost clock versus 4.30 GHz on the Ryzen 5 40, but the Ryzen 5 40 has a higher base clock at 2.80 GHz versus 2.00 GHz. The Ryzen 5 40 is the safer pick for software that depends on sustained base frequency. The P174i offers a Gen 4 PCIe interface with 16 lanes, while the Ryzen 5 40 is limited to Gen 3 with 4 lanes. For embedded systems that need expansion, the P174i is the clear specification winner. For a laptop or compact mobile device, the Ryzen 5 40's 15 W TDP against 28 W makes it the more efficient choice in the database's terms.

Architecture Differences

The Ryzen 5 40 uses the Zen 2 architecture on the Mendocino codename, built on a 6 nm process at TSMC. Its die size is 100 mm². The P174i uses the Gorgon Point codename with a Zen 5 / Zen 5c hybrid generation, built on a 4 nm process at TSMC with a 233 mm² die. The process node shrink from 6 nm to 4 nm is a major architectural shift, but the P174i's larger die reflects its higher core count and larger cache pool.

Core and thread counts differ substantially. The Ryzen 5 40 has 4 cores and 8 threads. The P174i has 10 cores and 20 threads, a 2.5x core advantage and 2.5x thread advantage. Cache hierarchies also diverge. The Ryzen 5 40 provides 64 KB L1 per core, 512 KB L2 per core, and 4 MB shared L3. The P174i provides 80 KB L1 per core, 1 MB L2 per core, and 16 MB L3. The P174i's L3 is 4x larger in total, and its per-core L2 is double.

Memory support differs in type and bandwidth. The Ryzen 5 40 supports LPDDR5 only, with dual-channel bus and 88.0 GB/s bandwidth. The P174i supports both DDR5 and LPDDR5X, also dual-channel, with slightly higher bandwidth at 89.6 GB/s. ECC memory is a decisive difference: the Ryzen 5 40 has no ECC support, while the P174i has ECC enabled. For embedded or server-adjacent workloads where memory corruption is unacceptable, only the P174i qualifies.

PCIe capabilities are another major split. The Ryzen 5 40 has Gen 3 with 4 lanes (CPU only). The P174i has Gen 4 with 16 lanes (CPU only). That is a 4x lane count increase and a full generation jump in bandwidth per lane. Integrated graphics also differ: the Ryzen 5 40 uses Radeon 610M, the P174i uses Radeon 880M. The database does not record graphics benchmark scores, so the comparison is qualitative, but the model number suggests a newer iGPU on the P174i.

Sockets are incompatible. The Ryzen 5 40 uses AMD Socket FT6; the P174i uses AMD Socket FP8. They are not interchangeable in any system design. Production status for both is Active, and both have locked multipliers. The Ryzen 5 40's release date is September 30, 2025, while the P174i's is February 28, 2026, making the P174i a later design by roughly five months.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors. The winsA and winsB fields are both zero. Direct comparison on identical tests is impossible from the recorded data. The analysis must rely on the Ryzen 5 40's standalone benchmark scores and the P174i's specification sheet.

The Ryzen 5 40's Cinebench R23 multi-core score of 4841 and single-core score of 1150 provide a baseline for its class. Its Cinebench R15 results are 790 multi-core and 165.5 single-core. PassMark results include a multi-thread score of 9341, single-thread score of 2477, integer math at 31598, floating point math at 15194, data compression at 141533, data encryption at 6646, extended instructions at 6437, find prime numbers at 20, random string sorting at 15124, and physics at 432. The average benchmark score sits at 15882.

The Ryzen 5 40's nearest rivals in the database are all enterprise or ultra-mobile parts. The AMD EPYC 75F3 has an average score of 15859, just 0.1% below the Ryzen 5 40. The Intel Core Ultra 5 134U averages 15910, 0.2% above. The AMD EPYC 9354P averages 15826, 0.4% below. The AMD EPYC 9334 averages 15940, 0.4% above. The Ryzen 5 40 sits squarely in this cluster, meaning its aggregate performance is statistically equivalent to those parts despite being a 4-core mobile chip. That is a notable result: a 15 W 4-core part matches enterprise 24-32 core server chips in the database's average score metric.

The P174i has no scores to interpret. Its percentile of 50 is a specification-based placement, not a measured result. The data cannot show where the P174i wins or loses on any benchmark because none exist. Any claim about its performance would be speculation, which the database does not support.

Specification Differences

The two processors differ in every core specification field. Cores: 4 versus 10. Threads: 8 versus 20. Base clock: 2.80 GHz versus 2.00 GHz. Boost clock: 4.30 GHz versus 5.00 GHz. TDP: 15 W versus 28 W. Socket: FT6 versus FP8. Architecture: Zen 2 versus Zen 5 / Zen 5c generation. Codename: Mendocino versus Gorgon Point. Process node: 6 nm versus 4 nm. Die size: 100 mm² versus 233 mm².

Cache differences are substantial. L1 per core: 64 KB versus 80 KB. L2 per core: 512 KB versus 1 MB. L3 total: 4 MB shared versus 16 MB. Memory support: LPDDR5 versus DDR5 and LPDDR5X. Memory bandwidth: 88.0 GB/s versus 89.6 GB/s. ECC memory: false versus true. PCIe: Gen 3 with 4 lanes versus Gen 4 with 16 lanes. Integrated graphics: Radeon 610M versus Radeon 880M. Release date: September 2025 versus February 2026.

Fields that match: manufacturer (AMD), memory bus (dual-channel), production status (Active), multiplier unlocked (false), part number (unknown), and launch MSRP (none recorded for either). The P174i's 4 nm node is two generations ahead of the Ryzen 5 40's 6 nm in process technology, but the P174i's larger die and higher TDP indicate it is not a simple efficiency play. The Ryzen 5 40's lower TDP and smaller die make it the lighter option for compact devices.

Where Each One Wins

The Ryzen 5 40 wins in every measured performance category because it is the only one with recorded benchmarks. Its Cinebench R23 multi-core score of 4841 and single-core score of 1150 are concrete data points. Its PassMark multi-thread score of 9341 and single-thread score of 2477 define its compute profile. The P174i cannot win a benchmark comparison because no benchmark results exist for it in the database.

The Ryzen 5 40 also wins on efficiency metrics. Its 15 W TDP is lower than the P174i's 28 W. Its base clock of 2.80 GHz is higher, which means sustained all-core workloads at base frequency run faster on the Ryzen 5 40. Its 6 nm process and 100 mm² die make it physically smaller and likely easier to cool in a thin chassis. The Radeon 610M integrated graphics are paired with a lower-power envelope, which suits basic display output rather than heavy GPU tasks.

The P174i wins on raw specification headroom. Its 10 cores and 20 threads double-plus the Ryzen 5 40's 4 cores and 8 threads. Its 5.00 GHz boost clock is 0.70 GHz higher. Its 16 MB L3 cache is four times larger. Its 4 nm process and 233 mm² die indicate a more complex, higher-end silicon. Its Gen 4 PCIe with 16 lanes is a massive I/O advantage for embedded systems that need to attach multiple accelerators, storage devices, or network interfaces. Its ECC memory support is a hard requirement for data-integrity-focused designs. Its DDR5 and LPDDR5X memory support offers more flexibility than the Ryzen 5 40's LPDDR5-only limitation.

Use-case split from the data: the Ryzen 5 40 is for fanless or low-power laptops, thin-and-light mobile devices, and any application where measured performance and low TDP are the priorities. Its 70th percentile ranking and average benchmark score of 15882 place it in credible company. The P174i is for embedded systems, industrial PCs, edge servers, or any platform where PCIe expansion, ECC memory, and a high boost clock matter more than verified benchmark scores. Its 50th percentile is a placeholder, not a performance verdict. The database cannot confirm the P174i's compute capability, so its wins are entirely architectural.
