AMD Ryzen AI Embedded P185 vs AMD Ryzen AI Max 385 Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a clear overall advantage for the AMD Ryzen AI Max 385, which wins 10 of the 11 shared Passmark tests. The AMD Ryzen AI Embedded P185 secures only one victory. The largest margin in favor of the Max 385 appears in the extended instructions test, where it scores 33873 versus 26544 for the P185, a difference of 21.6 percent. This indicates substantially better performance in workloads that leverage advanced CPU instruction sets such as AVX-512 or similar extensions.

A similarly large gap shows up in the find prime numbers test. The Max 385 records 165, while the P185 records 129, giving the Max 385 a 21.8 percent advantage. This test is highly dependent on raw integer throughput per core and efficient use of the processor pipeline. The consistency of the Max 385's wins across multiple single-threaded and lightly threaded workloads suggests its higher base clock of 3.60 GHz versus 2.00 GHz plays a decisive role.

In single-thread performance, the Max 385 scores 4060 compared to 3977 for the P185, a 2 percent edge. The same result appears in the duplicate singlethread entry. While this margin is modest, it reinforces the pattern that the Max 385 extracts more performance from each core. The floating point math test shows a narrower gap: 71105 for the Max 385 versus 70587 for the P185, only 0.7 percent apart. This near parity suggests that when both processors are allowed to run at full boost clocks, their FPU capabilities are comparable. The boost clock for the P185 is 5.10 GHz, slightly higher than the 5.00 GHz of the Max 385, which likely narrows the gap in this floating-point-heavy workload.

The data compression test favors the Max 385 with a score of 406505 against 374429, a 7.9 percent difference. This workload benefits from the larger 32 MB shared L3 cache on the Max 385, which reduces memory access latency for frequently used data. The P185's 16 MB L3 cache is half the size, and the benchmark results reflect that handicap. Random string sorting also goes to the Max 385, scoring 43725 versus 40557, a 7.2 percent edge. Sorting algorithms are memory-latency sensitive, and the Max 385's quad-channel memory interface with 256.0 GB/s bandwidth provides a substantial advantage over the P185's dual-channel setup at 89.6 GB/s.

The multithread test records 33705 for the Max 385 versus 31817 for the P185, a 5.6 percent difference. This is notable because the P185 has 12 cores and 24 threads, while the Max 385 has 8 cores and 16 threads. Despite having 50 percent more cores and threads, the P185 cannot overcome the Max 385's higher per-core performance and faster memory subsystem. The physics test follows a similar pattern: 1889 for the Max 385 versus 1772 for the P185, a 6.2 percent gap.

Data encryption shows a smaller difference, with the Max 385 at 19926 and the P185 at 19612, only 1.6 percent apart. This suggests that both processors have similar cryptographic acceleration capabilities within their respective architectures. The P185's sole win comes in integer math, where it scores 117832 against 107046 for the Max 385, a 10.1 percent advantage. The P185's additional four cores and eight threads likely drive this result, as integer math workloads scale well with core count when memory bandwidth is not the bottleneck.

Architecture Differences

The two processors come from different design families within AMD's mobile lineup. The Ryzen AI Embedded P185 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on Zen 5 and Zen 5c cores. The Ryzen AI Max 385 uses the Strix Halo codename and is built exclusively on Zen 5 architecture. Both are manufactured on a 4 nm process at TSMC, so the transistor density and power characteristics of the underlying process are identical.

The physical design differs significantly. The P185 has a single die measuring 233 mm², while the Max 385 uses a dual-die configuration with each die at 70.6 mm², for a combined area of approximately 141.2 mm². The smaller combined die area of the Max 385 suggests a more efficient use of silicon, though the P185's larger die accommodates more cores. The P185 packs 12 cores and 24 threads, while the Max 385 has 8 cores and 16 threads.

Cache hierarchies differ in both capacity and organization. Each processor gives each core 80 KB of L1 cache and 1 MB of L2 cache, so per-core cache allocation is identical. The L3 cache, however, is structured differently. The P185 offers 16 MB of L3 cache, while the Max 385 provides 32 MB of shared L3 cache. The shared designation on the Max 385 indicates that all eight cores can access the full 32 MB pool, whereas the P185's L3 is likely distributed across its core clusters. This larger shared cache on the Max 385 explains part of its advantage in data compression and sorting benchmarks.

Memory support also diverges. The P185 supports both DDR5 and LPDDR5X memory, while the Max 385 supports only LPDDR5X. The memory bus width differs substantially: the P185 uses a dual-channel configuration, while the Max 385 uses quad-channel. This directly translates into memory bandwidth: the P185 offers 89.6 GB/s, while the Max 385 delivers 256.0 GB/s, nearly three times higher. Both processors support ECC memory, which is notable for embedded and workstation-class workloads.

The integrated graphics differ as well. The P185 carries a Radeon 890M, while the Max 385 carries a Radeon 8050S. The benchmark data does not include graphics tests, so direct GPU performance comparisons are not available. The sockets also differ: the P185 uses AMD Socket FP8, while the Max 385 uses AMD Socket FP11. This means the two processors are not physically interchangeable on the same motherboard.

Power characteristics show a significant divergence. The P185 has a TDP of 28 watts, while the Max 385 has a TDP of 55 watts. The higher power envelope of the Max 385 allows it to sustain higher base clocks of 3.60 GHz versus 2.00 GHz for the P185. Boost clocks are closer: 5.10 GHz for the P185 and 5.00 GHz for the Max 385. The P185's lower TDP supports its positioning for embedded applications where thermal and power budgets are constrained.

Release timing also differs. The Max 385 was released on 2025-01-05, while the P185 followed on 2026-02-28. Both processors are currently marked as Active in production status. The P185's part number is listed as unknown, while the Max 385 has part number 100-000001424.

Where Each One Wins

The AMD Ryzen AI Max 385 dominates the benchmark suite. It wins in data compression, data encryption, extended instructions, find prime numbers, floating point math, multithread, physics, random string sorting, single-thread, and the duplicate singlethread test. Its largest margins come in extended instructions (21.6 percent) and find prime numbers (21.8 percent). These wins point to workloads that favor high per-core clock speeds, large shared caches, and rapid memory access. The quad-channel 256.0 GB/s memory interface gives it a decisive edge in bandwidth-sensitive tasks like data compression and string sorting. Its higher TDP of 55 watts allows it to sustain higher clocks under load, which benefits sustained multithreaded execution despite having fewer cores.

The AMD Ryzen AI Embedded P185 wins only in integer math, where it scores 10.1 percent higher than the Max 385. This result suggests that its 12 cores and 24 threads provide an advantage when the workload scales with core count and does not depend heavily on memory bandwidth or cache size. Integer math operations often parallelize well across many cores, and the P185's additional four cores allow it to process more operations concurrently. The P185 also offers a higher boost clock at 5.10 GHz, which may contribute to its performance in bursty single-threaded integer workloads.

Beyond benchmark wins, the P185 has structural advantages for certain use cases. Its lower 28 watt TDP makes it suitable for thermally constrained embedded environments. Its support for both DDR5 and LPDDR5X memory gives system designers flexibility in memory selection. The P185's larger die at 233 mm² and its Gorgon Point codename with Zen 5 and Zen 5c core mix suggest a design optimized for throughput in multi-core scenarios. The Max 385, released earlier, focuses on delivering high per-core performance and memory bandwidth within a dual-die layout.

The Verdict

The benchmark data clearly favors the AMD Ryzen AI Max 385 for general performance. It wins 10 of 11 head-to-head tests, including all of the most common workloads such as multithread, single-thread, data compression, and encryption. Its 32 MB shared L3 cache and 256.0 GB/s memory bandwidth provide a substantial infrastructure advantage that the P185 cannot offset with more cores. The Max 385's 88th percentile ranking among all CPUs, alongside its nearest rivals such as the Intel Core i9-13950HX and Intel Core i5-13600, places it in the upper mid-range of mobile processors. Its average benchmark score of 44309 is lower than the P185's 62839, but this average includes Cinebench tests that are not recorded for the P185, so direct comparison of averages is not meaningful.

The AMD Ryzen AI Embedded P185 holds a 93rd percentile ranking, higher than the Max 385's 88th percentile. This ranking reflects the P185's position among all CPUs in the database, and its average benchmark score of 62839 is bolstered by the absence of lower-scoring Cinebench entries. The P185's nearest rivals include the Intel Core Ultra 7 255HX and the AMD Ryzen AI 9 PRO 465, with delta percentages within 0.5 percent. The P185's single win in integer math demonstrates that its core count advantage is real but narrowly applicable.

For users prioritizing raw performance across diverse workloads, the Max 385 is the stronger choice based on the recorded data. For applications that require integer throughput above all else, or that operate within a 28 watt power envelope, the P185 has a specific role. The P185's embedded positioning, dual-channel memory, and support for both DDR5 and LPDDR5X make it a flexible option for systems where power efficiency and memory type flexibility are priorities. The Max 385's quad-channel LPDDR5X requirement and 55 watt TDP limit it to platforms that can accommodate higher power draw.

The data does not indicate a universal winner. It shows a processor with broader performance strengths in the Max 385 and a processor with a specialized strength in integer math and lower power consumption in the P185. Selection should follow the workload profile and platform constraints.
