AMD Ryzen 5 40 vs AMD Ryzen AI Embedded P164i Comparison

Head-to-Head Benchmarks

The database contains a complete benchmark profile for the AMD Ryzen 5 40, while the AMD Ryzen AI Embedded P164i has no recorded benchmark scores. This makes a direct score-by-score comparison impossible. However, the available data for the Ryzen 5 40 can be positioned against its nearest rivals to establish a performance baseline.

The Ryzen 5 40 records an average benchmark score of 15,882, placing it at the 70th percentile of all CPUs in the database. Its closest competitor is the AMD EPYC 75F3, which averages 15,859, a delta of 0.1% in favor of the Ryzen 5 40. The Intel Core Ultra 5 134U scores 15,910, putting it 0.2% ahead of the Ryzen 5 40. The AMD EPYC 9354P trails at 15,826, a 0.4% deficit, and the AMD EPYC 9334 sits at 15,940, leading the Ryzen 5 40 by 0.4%.

Looking at individual workloads, the Ryzen 5 40 shows a strong multi-core result in Cinebench R23, scoring 4,841. Its single-core result in the same test is 1,150. In Cinebench R15, the multi-core score is 790 and the single-core score is 165.5. These figures establish a mid-range mobile profile, consistent with a 15-watt processor.

The PassMark suite reveals more granular strengths. The data compression score is 141,533, a notably high figure for a mobile chip. Data encryption reaches 6,646, and extended instructions score 6,437. Integer math scores 31,598, while floating point math scores 15,194. Random string sorting records 15,124. The multithread score is 9,341, and the single-thread score is 2,477. Find prime numbers scores just 20, and physics scores 432.

Because the Ryzen AI Embedded P164i has no benchmark entries, the head-to-head section relies on architectural and specification deltas rather than measured performance. The data confirms that the Ryzen 5 40 is a benchmarked, active mobile processor with a defined competitive position, while the P164i is listed without any recorded performance data.

Where Each One Wins

Without benchmark scores for the Ryzen AI Embedded P164i, the win analysis must be derived from specifications and the known performance of the Ryzen 5 40.

The Ryzen 5 40 wins in power efficiency expectations. Its 15-watt TDP is lower than the P164i's 28 watts. The Ryzen 5 40 also uses the smaller Mendocino die at 100 mm², compared to the P164i's 233 mm² die. For thermally constrained mobile designs, the lower TDP and smaller die suggest a lighter cooling requirement.

The Ryzen AI Embedded P164i wins on core and thread count. It offers 8 cores and 16 threads, double the Ryzen 5 40's 4 cores and 8 threads. Its boost clock reaches 5.00 GHz, higher than the Ryzen 5 40's 4.30 GHz. The P164i also has a larger L3 cache at 8 MB, versus 4 MB on the Ryzen 5 40. Per-core L1 and L2 caches are also larger: 80 KB and 1 MB per core respectively, versus 64 KB and 512 KB per core.

Memory support favors the P164i. It supports both DDR5 and LPDDR5X, while the Ryzen 5 40 supports only LPDDR5. Memory bandwidth is slightly higher on the P164i at 89.6 GB/s, compared to 88.0 GB/s. The P164i also supports ECC memory, which the Ryzen 5 40 does not.

PCIe connectivity is another clear win for the P164i. It provides Gen 4 with 16 lanes, while the Ryzen 5 40 provides Gen 3 with 4 lanes. Integrated graphics also differ: the P164i uses the Radeon 880M, while the Ryzen 5 40 uses the Radeon 610M.

The Ryzen 5 40 is built on a 6 nm process, while the P164i uses 4 nm. The P164i's architecture is Zen 5 / Zen 5c under the Gorgon Point codename, whereas the Ryzen 5 40 uses Zen 2 with the Mendocino codename. The P164i's release date is later, 2026-03-08, compared to 2025-09-30 for the Ryzen 5 40.

Architecture Differences

The two processors come from different design generations. The AMD Ryzen 5 40 uses the Zen 2 architecture under the Mendocino codename, built on a 6 nm process at TSMC. The AMD Ryzen AI Embedded P164i uses Zen 5 / Zen 5c under the Gorgon Point codename, built on a 4 nm process, also at TSMC.

Die size differs substantially. The Ryzen 5 40 has a 100 mm² die, while the P164i measures 233 mm². The larger die on the P164i corresponds to a more complex design with more cores and a larger cache hierarchy.

Cache organization reflects the generational gap. The Ryzen 5 40 provides 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The P164i provides 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The P164i's per-core cache increases are consistent with the newer Zen 5 design.

Memory architecture also differs. The Ryzen 5 40 supports LPDDR5 memory over a dual-channel bus with 88.0 GB/s bandwidth and no ECC support. The P164i supports DDR5 and LPDDR5X over a dual-channel bus with 89.6 GB/s bandwidth and ECC support enabled.

PCIe implementation is a major architectural split. The Ryzen 5 40 uses Gen 3 with 4 CPU lanes. The P164i uses Gen 4 with 16 CPU lanes. This gives the P164i significantly more expansion and I/O headroom.

Integrated graphics differ as well. The Ryzen 5 40 pairs with the Radeon 610M, while the P164i uses the Radeon 880M. The newer Radeon 880M is tied to the Zen 5 platform and the later release date.

The P164i's socket is AMD Socket FP8, while the Ryzen 5 40 uses AMD Socket FT6. These are incompatible sockets, meaning platform choice dictates which processor can be used.

The Verdict

The data shows two very different mobile processors. The AMD Ryzen 5 40 is a benchmarked, low-power part with a 15-watt TDP, 4 cores, and a 6 nm Zen 2 design. Its average benchmark score of 15,882 places it at the 70th percentile, with its closest rival, the AMD EPYC 75F3, just 0.1% behind. This indicates a solid mid-range mobile performer.

The AMD Ryzen AI Embedded P164i is a higher-specification part on paper: 8 cores, 16 threads, a 5.00 GHz boost clock, 4 nm process, ECC support, Gen 4 PCIe with 16 lanes, and a newer Radeon 880M iGPU. Its 28-watt TDP and 233 mm² die indicate a more power-hungry and physically larger design. The absence of benchmark scores means its real-world performance cannot be quantified from the database.

Buyers who need a measured, efficient mobile processor with an established competitive position in the database should look at the Ryzen 5 40. Buyers who need more cores, a higher boost clock, ECC memory, and newer I/O standards should consider the Ryzen AI Embedded P164i, but they should note that the database has no recorded benchmarks to confirm its performance level. The specification sheet favors the P164i in raw capability, while the Ryzen 5 40 is the only one of the two with verified performance data.
