AMD Ryzen 9 270 vs AMD Ryzen AI Embedded P185 Comparison

The AMD Ryzen 9 270 and AMD Ryzen AI Embedded P185 are both active mobile processors on the AMD Socket FP8 platform, yet they target different priorities within the same design envelope. The Ryzen 9 270 is a Zen 4 Hawk Point part with a 45 W TDP and a high 5.20 GHz boost clock, while the Ryzen AI Embedded P185 is a Zen 5 / Zen 5c Gorgon Point chip with 12 cores and a much lower 28 W TDP. The recorded benchmarks show a clear split: the Ryzen 9 270 wins in a handful of specific tasks, while the Ryzen AI Embedded P185 dominates in raw throughput and single-threaded execution. The data indicates that these are not direct competitors but rather complementary choices for different workloads.

Where Each One Wins

The AMD Ryzen 9 270 takes three of the eleven recorded head-to-head benchmark wins. Its most decisive victory is in passmark_data_encryption, where it scores 20852 against 19612 for the Ryzen AI Embedded P185, a 6.3% advantage. It also wins passmark_extended_instructions with a narrow 0.7% lead (26729 versus 26544) and passmark_random_string_sorting with a 5.6% margin (42819 versus 40557). These results suggest that the Ryzen 9 270 is better suited for encryption workloads, extended instruction set operations, and certain types of sorting algorithms. The encryption win is particularly notable given the Ryzen 9 270's lower core count, indicating that its Zen 4 architecture at 5.20 GHz boost delivers strong per-core performance in this specific area.

The AMD Ryzen AI Embedded P185 wins the remaining eight benchmarks, with margins ranging from 4.9% to 31.8%. Its largest win is in passmark_find_prime_numbers, where it scores 129 versus 88, a 31.8% advantage. It also shows substantial leads in passmark_physics (1772 versus 1365, a 23% gap), passmark_integer_math (117832 versus 98266, a 16.6% gap), and passmark_floating_point_math (70587 versus 60122, a 14.8% gap). The P185 wins passmark_multithread with 31817 versus 29089, an 8.6% margin, and passmark_data_compression with 374429 versus 351398, a 6.2% margin. It also takes passmark_single_thread with 3977 versus 3784, a 4.9% lead. This pattern indicates that the P185 is the stronger all-around performer for multithreaded, physics, math, and prime number workloads, as well as for single-threaded tasks.

Architecture Differences

The two processors share the same 4 nm TSMC process node and the AMD Socket FP8, but their internal designs diverge significantly. The Ryzen 9 270 uses the Zen 4 architecture under the codename Hawk Point, featuring 8 cores and 16 threads. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The die size is 178 mm² with 25,000 million transistors. The Ryzen AI Embedded P185, by contrast, uses the Zen 5 / Zen 5c architecture under the codename Gorgon Point, with 12 cores and 24 threads. Its L1 cache is larger at 80 KB per core, L2 remains 1 MB per core, and L3 is 16 MB. The P185's die size is larger at 233 mm², though its transistor count is not recorded.

The Ryzen 9 270 has a base clock of 4.00 GHz and a boost clock of 5.20 GHz, while the P185 has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The TDP also differs dramatically: 45 W for the Ryzen 9 270 versus 28 W for the P185. This suggests that the P185 achieves its higher core count and newer architecture within a lower thermal envelope, likely relying on the efficiency of Zen 5 / Zen 5c cores. The integrated graphics differ as well: the Ryzen 9 270 uses Radeon 780M, while the P185 uses Radeon 890M. Memory support is another point of divergence: the Ryzen 9 270 supports DDR5 only, while the P185 supports both DDR5 and LPDDR5X. Both are dual-channel with 89.6 GB/s bandwidth. The P185 includes ECC memory support, a feature absent on the Ryzen 9 270. PCIe connectivity also differs: the Ryzen 9 270 offers Gen 4 with 20 lanes (CPU only), while the P185 offers Gen 4 with 16 lanes (CPU only).

Head-to-Head Benchmarks

The largest single benchmark gap favors the Ryzen AI Embedded P185 in passmark_find_prime_numbers, where its score of 129 beats the Ryzen 9 270's 88 by 31.8%. This is a clear indication that the P185's higher core count and Zen 5 / Zen 5c architecture are particularly effective for prime number calculations. The second-largest win for the P185 is passmark_physics, with 1772 versus 1365, a 23% lead. Physics simulations often scale with core count and memory bandwidth, both of which favor the P185. In passmark_integer_math, the P185 scores 117832 against 98266, a 16.6% advantage, and in passmark_floating_point_math, it scores 70587 against 60122, a 14.8% advantage. These math-oriented workloads show the P185's ability to leverage its 12 cores and 24 threads.

The P185 also wins passmark_multithread with 31817 versus 29089, an 8.6% margin, and passmark_data_compression with 374429 versus 351398, a 6.2% margin. In passmark_single_thread, the P185 edges ahead with 3977 versus 3784, a 4.9% lead. This single-threaded win is notable because the Ryzen 9 270 has a higher boost clock of 5.20 GHz, yet the P185's Zen 5 architecture at 5.10 GHz still delivers better per-thread performance. The Ryzen 9 270's wins are smaller but meaningful. In passmark_data_encryption, it scores 20852 versus 19612, a 6.3% margin. In passmark_random_string_sorting, it scores 42819 versus 40557, a 5.6% margin. The narrowest win is passmark_extended_instructions, where the Ryzen 9 270 scores 26729 versus 26544, just 0.7% ahead. These results show that the Ryzen 9 270 retains an edge in encryption and sorting, likely due to its higher clock speed and Zen 4's specific instruction handling.

The overall average benchmark scores reinforce this split. The Ryzen 9 270 holds an avgBenchmarkScore of 40246, placing it in the 87th percentile of all CPUs. Its nearest rivals include the Intel Core i9-13905H with an average score of 40313 (a delta of -0.2%), the Intel Xeon 6369P at 40327 (-0.2%), the Intel Core 5 221E at 40144 (0.3%), and the AMD Ryzen 7 7700 at 40081 (0.4%). The Ryzen AI Embedded P185, by contrast, has an avgBenchmarkScore of 62839, placing it in the 93rd percentile. Its nearest rivals are the Intel Core Ultra 7 255HX at 62738 (0.2%), the Intel Core i7-13790F at 63080 (-0.4%), the Intel Core Ultra 7 265HX at 63173 (-0.5%), and the AMD Ryzen AI 9 PRO 465 at 62498 (0.5%). The 226-point difference in average score between the P185 and the Ryzen 9 270, combined with the 6-percentile gap, shows that the P185 is in a higher performance tier overall.

The Verdict

The data indicates that the AMD Ryzen AI Embedded P185 is the stronger processor for most workloads. It wins eight of eleven benchmarks, including all the major compute-intensive tests: multithread, integer math, floating point math, physics, and prime numbers. Its single-threaded performance also exceeds the Ryzen 9 270 despite a lower boost clock, which points to a more efficient architecture. The P185's 93rd percentile ranking and higher average score of 62839 place it well above the Ryzen 9 270's 87th percentile and 40246 average score. For users prioritizing raw performance, especially in math, physics, and multithreaded applications, the P185 is the clear choice.

The AMD Ryzen 9 270 is the better option only in specific scenarios. Its wins in data encryption, extended instructions, and random string sorting indicate that it handles certain cryptographic and sorting workloads with greater efficiency. Its higher boost clock of 5.20 GHz and lower core count may also make it more suitable for tasks that rely on fewer, faster threads in those particular areas. However, its overall performance is substantially lower, and its 45 W TDP versus the P185's 28 W means it draws more power while delivering less compute in most tests. The Ryzen 9 270 might be preferable for a niche use case where encryption or specific sorting algorithms are the primary workload, but for general-purpose computing, the Ryzen AI Embedded P185's benchmark results are decisively better. The P185 also offers ECC memory support and LPDDR5X compatibility, which are not available on the Ryzen 9 270.
