Architecture Differences

The two processors come from different architectural generations, and the data reflects a substantial divide in design philosophy. The AMD Ryzen 5 40 uses the Zen 2 architecture under the Mendocino codename, built on a 6 nm process at TSMC. It features 4 cores and 8 threads, with a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The Ryzen AI Embedded P185, by contrast, uses the Gorgon Point codename with a Zen 5 / Zen 5c generation, built on a 4 nm process at TSMC. It packs 12 cores and 24 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz.

Cache hierarchies differ sharply. The Ryzen 5 40 has 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Ryzen AI Embedded P185 has 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3. The P185's larger per-core caches and quadrupled L3 capacity provide a structural advantage for workloads that repeatedly access working sets.

The integrated graphics also differ. The Ryzen 5 40 carries a Radeon 610M, while the Ryzen AI Embedded P185 carries a Radeon 890M. The database does not list separate graphics benchmarks, but the GPU tier difference aligns with the P185's higher overall positioning.

Die size tells a story too. The Ryzen 5 40 has a die size of 100 mm², while the Ryzen AI Embedded P185 has a die size of 233 mm². The larger die accommodates more cores, more cache, and a more powerful iGPU, which explains the P185's higher transistor count despite no explicit transistor figure in the pack.

Memory support diverges as well. The Ryzen 5 40 supports LPDDR5 only, while the Ryzen AI Embedded P185 supports both DDR5 and LPDDR5X. The P185 also enables ECC memory, a feature absent on the Ryzen 5 40. PCIe capability differs: the Ryzen 5 40 offers Gen 3 with 4 lanes (CPU only), while the P185 offers Gen 4 with 16 lanes (CPU only). That quadrupled lane count and newer generation matters for embedded workloads that rely on fast peripheral connectivity.

Sockets differ too. The Ryzen 5 40 uses AMD Socket FT6, while the P185 uses AMD Socket FP8. Neither processor has an unlocked multiplier, so overclocking is not a differentiator.

Head-to-Head Benchmarks

The recorded head-to-head data shows a dominant sweep by the AMD Ryzen AI Embedded P185 across all 11 passmark tests. The largest margin appears in the find prime numbers test, where the P185 scores 129 against the Ryzen 5 40's 20, a delta of 84.5 percent. This test is highly sensitive to core count and clock speed, and the P185's 12 cores and 5.10 GHz boost clock deliver a crushing advantage.

The floating point math test shows a similar story. The P185 scores 70587, while the Ryzen 5 40 scores 15194, a delta of 78.5 percent. Integer math follows closely: 117832 versus 31598, a delta of 73.2 percent. These results indicate that the P185's Zen 5 cores process arithmetic workloads at more than triple the throughput of the Zen 2 cores in the Ryzen 5 40.

The extended instructions test, which measures SIMD and specialized instruction throughput, shows a delta of 75.7 percent in favor of the P185 (26544 versus 6437). This suggests the P185's newer microarchitecture handles advanced instruction sets far more efficiently.

Data compression and encryption tests show smaller but still decisive gaps. Compression scores 374429 on the P185 versus 141533 on the Ryzen 5 40, a delta of 62.2 percent. Encryption scores 19612 versus 6646, a delta of 66.1 percent. Random string sorting shows a delta of 62.7 percent (40557 versus 15124).

The multithread test, which aggregates all-core performance, shows the P185 at 31817 versus the Ryzen 5 40's 9341, a delta of 70.6 percent. Physics simulation shows a delta of 75.6 percent (1772 versus 432), another workload that scales with both core count and frequency.

Single-thread performance shows the smallest gap, but it still favors the P185 substantially. The single-thread test records 3977 on the P185 versus 2477 on the Ryzen 5 40, a delta of 37.7 percent. This narrower margin reflects the fact that single-thread workloads depend less on core count and more on per-core IPC and boost clocks. The P185's 5.10 GHz boost clock and Zen 5 architecture still deliver a commanding lead.

The database also tracks the delta percentages relative to each processor's nearest rivals. The Ryzen 5 40 sits within 0.4 percent of AMD EPYC 75F3, EPYC 9354P, and EPYC 9334 models, and within 0.2 percent of the Intel Core Ultra 5 134U. The P185 sits within 0.5 percent of the Intel Core Ultra 7 255HX, Core i7-13790F, Core Ultra 7 265HX, and AMD Ryzen AI 9 PRO 465. These proximity values confirm that both processors are well-positioned within their respective performance tiers.

Where Each One Wins

Based on the recorded data, the AMD Ryzen AI Embedded P185 wins every measured workload category. The passmark suite covers data compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithread throughput, physics simulation, random string sorting, and single-thread performance. The P185 leads in all of them.

The Ryzen 5 40 does not register a single head-to-head win. This does not mean it lacks utility, but within the benchmark database, it trails across the board. The closest contest is single-thread performance, where the P185 leads by 37.7 percent. That is still a decisive margin, but it is the smallest gap in the entire comparison. For workloads that are strictly single-threaded and latency-bound, the Ryzen 5 40's deficit is less severe than in heavily parallel tasks.

The P185's largest advantages appear in prime number finding (84.5 percent), floating point math (78.5 percent), extended instructions (75.7 percent), and physics (75.6 percent). These tasks reward core count, cache capacity, and per-core IPC simultaneously. The P185's 12 cores, 16 MB of L3, and Zen 5 architecture combine to produce these outsized margins.

For workloads involving data compression, encryption, or string sorting, the P185 leads by margins between 62.2 and 66.1 percent. These tasks are memory-latency sensitive and benefit from the P185's larger caches and higher memory bandwidth (89.6 GB/s versus 88.0 GB/s).

The Ryzen 5 40 does have one structural advantage: lower TDP. At 15 W versus 28 W, it draws less power under load. The database does not include power measurements, but the TDP figures indicate a lower thermal envelope, which matters for fanless or tightly constrained mobile designs.

The Verdict

The data points to a clear hierarchy. The AMD Ryzen AI Embedded P185 outperforms the AMD Ryzen 5 40 in every recorded benchmark, with deltas ranging from 37.7 percent in single-thread work to 84.5 percent in prime number calculation. The P185's average benchmark score of 62839 places it in the 93rd percentile of all CPUs, while the Ryzen 5 40's 15882 average places it in the 70th percentile.

For applications that need heavy parallel throughput, encryption, compression, or advanced instruction execution, the P185 is the only choice supported by the data. Its 12 cores, 24 threads, 16 MB of L3, and 5.10 GHz boost clock deliver results that the Ryzen 5 40 cannot approach. The P185 also offers ECC memory support and PCIe Gen 4 with 16 lanes, making it suitable for embedded workloads that require data integrity and fast peripheral I/O.

For scenarios where power consumption is the primary constraint, the Ryzen 5 40's 15 W TDP is a meaningful advantage over the P185's 28 W. The Ryzen 5 40 also uses a smaller die (100 mm² versus 233 mm²), which may simplify thermal management in compact designs. Its 4 cores and 8 threads are sufficient for lighter workloads, and its 4.30 GHz boost clock provides respectable single-thread responsiveness, though the P185 still leads by 37.7 percent in that metric.

The database records zero wins for the Ryzen 5 40 across the head-to-head suite. Users who prioritize raw performance in any measured category should select the P185. Users who must minimize power draw and can accept lower absolute scores may consider the Ryzen 5 40, but the benchmark evidence provides no performance-based reason to prefer it. The P185's nearest rivals, including the Intel Core Ultra 7 255HX and Core i7-13790F, sit within 0.5 percent of its average score, confirming that it competes at a far higher tier than the Ryzen 5 40.
