Head-to-Head Benchmarks

The largest AMD win is integer math. The AMD Ryzen AI Embedded P185 scores 117832, the Intel Core Ultra 5 225T scores 59543, and the delta is 97.9%. This is nearly double the output. The second largest AMD win is data compression at 374429 versus 233998, a 60% advantage. Random string sorting also favors AMD heavily: 40557 versus 28774, a 41% lead. Extended instructions go to AMD at 26544 versus 20083, a 32.2% lead. Multithread goes to AMD at 31817 versus 25358, a 25.5% lead. Data encryption is closer, with AMD at 19612 versus Intel's 18289, only a 7.2% edge.

The largest Intel win is find prime numbers. Intel scores 284, AMD scores 129, and the delta is 54.6% in Intel's favor. Floating point math goes to Intel at 82751 versus 70587, a 14.7% lead. Physics goes to Intel at 2053 versus 1772, a 13.7% lead. Single-thread goes to Intel at 4348 versus 3977, an 8.5% lead. The two single-thread entries in the database are identical for both CPUs, confirming the same recorded score of 3977 for AMD and 4348 for Intel.

The data also shows a notable separation in average benchmark scores. AMD's average is 62839, which places it near rivals like the Intel Core Ultra 7 255HX at 62738 (0.2% behind) and the Intel Core Ultra 7 265HX at 63173 (0.5% ahead). Intel's average is 30468, which places it near the Intel Core i9-11980HK at 30422 (0.2% behind) and the AMD Ryzen 5 7640HS at 30390 (0.3% ahead). These two CPUs are not competing in the same performance tier according to the database. AMD's average is roughly double Intel's average.

The PassMark physics test is interesting because Intel wins it despite losing multithread. Intel scores 2053, AMD scores 1772. Physics often tracks single-core efficiency, and Intel's single-thread lead of 8.5% aligns with that. Similarly, floating point math favors Intel at 82751, while integer math strongly favors AMD. This split suggests the two architectures handle different math workloads differently: AMD's extra threads and 4 nm process drive integer throughput, while Intel's 3 nm process and larger per-core cache drive floating point and prime number generation.

The data compression result deserves emphasis. AMD's 374429 is 60% higher than Intel's 233998. Compression workloads often scale with thread count and memory bandwidth. AMD has 24 threads versus Intel's 10, but Intel has higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s. The thread advantage appears to outweigh the bandwidth advantage in this test. Random string sorting also relies heavily on parallel execution, and AMD's 41% win reinforces that pattern.

The encryption test is the closest head-to-head result. AMD scores 19612, Intel scores 18289, and the delta is only 7.2%. Both CPUs handle encryption similarly, but AMD still takes the lead. The extended instructions test shows a 32.2% AMD advantage, which indicates AMD's instruction set extensions perform better in the recorded workload.

The prime number test is the opposite extreme. Intel's 284 is more than double AMD's 129. This is a 54.6% difference, and it is the only benchmark where the winner leads by more than 50% in Intel's favor. Prime number finding is typically single-threaded and latency-sensitive, so Intel's 4.90 GHz boost clock versus AMD's 5.10 GHz boost clock is not the deciding factor. The architecture's per-core efficiency is more relevant.
