AMD Ryzen AI 9 HX PRO 475 vs Intel Core 9 273PE Comparison

# Where Each One Wins

The AMD Ryzen AI 9 HX PRO 475 takes six of the eleven head-to-head benchmark wins, while the Intel Core 9 273PE takes five. The split is close, but the wins cluster around distinct workload types. AMD leads in data compression (461,650 vs 405,885, a 13.7% margin), data encryption (23,132 vs 22,719, a 1.8% margin), extended instructions (31,969 vs 24,630, a 29.8% margin), random string sorting (48,894 vs 45,098, an 8.4% margin), and both single-thread tests (4,301 vs 3,650, a 17.8% margin in each). These results indicate a strong showing in single-threaded performance, encryption workloads, and compression tasks.

Intel's wins are concentrated in math-heavy and physics-oriented benchmarks. The Core 9 273PE leads in find prime numbers (203 vs 130, a 36% margin), floating-point math (107,884 vs 79,887, a 26% margin), integer math (139,410 vs 126,829, a 9% margin), the PassMark multithread test (36,810 vs 36,487, a 0.9% margin), and physics (3,120 vs 1,877, a 39.8% margin). The physics and prime-number results are particularly decisive for Intel, suggesting that the Core 9 273PE handles heavy mathematical computation and simulation-style workloads with a clear advantage.

The multithread score is the closest contest between the two processors. Intel wins it by only 0.9%, which is effectively a tie within measurement noise. The overall average benchmark scores reflect a different picture: AMD's average is 74,496, while Intel's is 49,845. That difference is substantial, but it stems from the fact that AMD's benchmark list includes more PassMark entries while Intel's list includes Cinebench R15, R20, and R23 results, which are absent from the AMD data. Direct head-to-head comparisons should therefore rely on the shared PassMark tests.

For users prioritizing single-thread responsiveness, encryption, and data compression, the AMD processor is the clear pick. For those running floating-point-heavy simulations, integer math, or physics calculations, the Intel processor delivers higher scores. The workload split is clean: AMD wins the memory-oriented and scalar workloads, while Intel wins the arithmetic-heavy and physics workloads.

# Architecture Differences

The two processors come from different manufacturers, foundries, and design philosophies. AMD's Ryzen AI 9 HX PRO 475 uses the Zen 5 architecture on a 4 nm TSMC process, with the codename Gorgon Point and the Ryzen AI PRO 400 generation (which combines Zen 5 and Zen 5c cores). The Intel Core 9 273PE uses the Bartlett Lake codename, belongs to the Core 9 generation, and is built on a 10 nm Intel process. The process node difference is notable: 4 nm versus 10 nm, which typically affects power efficiency and transistor density, though the database does not provide transistor counts.

Both processors have 12 cores and 24 threads, so the thread count is identical. The cache layouts differ. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3. Intel provides the same 80 KB L1 per core, but 2 MB of L2 per core and 36 MB of shared L3. That means Intel has double the L2 per core and more than double the total L3, which likely contributes to its higher integer and floating-point scores in cache-sensitive workloads.

The memory support differs as well. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both use a dual-channel memory bus, and both achieve the same memory bandwidth of 89.6 GB/s. ECC memory is supported on both processors. The PCIe interfaces differ: AMD uses Gen 4 with 16 lanes (CPU only), while Intel uses Gen 5 with 16 lanes (CPU only). Intel's PCIe Gen 5 support provides higher bandwidth for expansion devices, though the database does not quantify the speed advantage.

The integrated graphics differ significantly. AMD includes the Radeon 890M, while Intel includes UHD Graphics 730. The database does not provide benchmark scores for these iGPUs, but the product positioning differs: the AMD chip is a mobile processor in the AMD Socket FP8, while the Intel chip is a desktop processor in Intel Socket 1700. The market segments reflect this: AMD is in the Mobile segment, Intel in the Desktop segment.

Clock speeds also differ. AMD's base clock is 2.00 GHz and boost clock is 5.20 GHz. Intel's base clock is 2.30 GHz and boost clock is 5.70 GHz. Intel has a higher base and boost clock, which helps explain its strong physics and prime-number results. The TDP differs as well: AMD is rated at 28 W, Intel at 65 W. The Intel part draws more power, which is consistent with a desktop processor, while AMD's lower TDP suits mobile use.

The release dates differ by several months. AMD's release date is January 4, 2026, while Intel's is March 8, 2026. Both are listed as Active in production status. Neither processor has an unlocked multiplier, so overclocking is not supported on either.

# Head-to-Head Benchmarks

The largest AMD win comes in extended instructions, where the Ryzen AI 9 HX PRO 475 scores 31,969 against Intel's 24,630. That is a 29.8% lead, indicating a strong advantage in workloads that leverage SIMD or specialized instruction sets. The single-thread tests show a 17.8% margin in AMD's favor, with both PassMark single-thread and singlethread scores at 4,301 versus 3,650. That is a meaningful gap for single-core-bound applications.

Data compression also favors AMD by 13.7%, with scores of 461,650 versus 405,885. Random string sorting goes to AMD by 8.4%, at 48,894 versus 45,098. Data encryption is the narrowest AMD win, at 1.8%, with 23,132 versus 22,719. These four wins cover compression, sorting, encryption, and instruction throughput, all of which benefit from the Zen 5 architecture and its 4 nm process.

The largest Intel win comes in physics, where the Core 9 273PE scores 3,120 against AMD's 1,877. That is a 39.8% margin, by far the biggest delta in either direction. Find prime numbers follows at 36% (203 vs 130), and floating-point math at 26% (107,884 vs 79,887). Integer math goes to Intel by 9% (139,410 vs 126,829). The multithread test goes to Intel by a razor-thin 0.9% (36,810 vs 36,487), which is the closest result in the entire head-to-head set.

The physics result is the standout. A 39.8% lead in physics simulation-style workloads suggests that Intel's higher clocks (2.30 GHz base, 5.70 GHz boost) and larger cache (36 MB L3, 2 MB L2 per core) deliver a substantial edge in iterative, cache-resident calculations. The prime number test, which is often sensitive to integer division and branch prediction, also favors Intel strongly. Floating-point math favors Intel by more than a quarter, indicating that the Core 9 273PE is better suited to scientific computing and numerical analysis.

The benchmark data reveals a clear pattern: AMD wins scalar, memory-latency-sensitive, and single-threaded tasks; Intel wins parallel math, physics, and integer-heavy tasks. The counts are nearly even at 6-5 in AMD's favor, but the margins tell the story. AMD's wins range from 1.8% to 29.8%, while Intel's wins range from 0.9% to 39.8%. Intel's biggest wins are larger than AMD's biggest wins, but AMD has more consistent advantages across its winning set.

# The Verdict

The data supports a clear split based on workload. The AMD Ryzen AI 9 HX PRO 475 is the choice for single-threaded applications, data compression, encryption, random string sorting, and extended instruction workloads. Its 17.8% single-thread lead over Intel is substantial, and its 29.8% lead in extended instructions is the largest AMD advantage. The 94th percentile ranking among all CPUs, compared to Intel's 90th, also indicates that AMD sits higher in the overall performance distribution.

The Intel Core 9 273PE is the choice for physics simulations, prime number calculations, floating-point math, integer math, and multithreaded workloads. Its 39.8% physics lead and 36% prime-number lead are dominant margins. The 65 W TDP and desktop socket position it for stationary, power-unconstrained environments. The 36 MB L3 cache and 5.70 GHz boost clock likely drive these math-heavy wins.

For mobile users who need a 28 W processor with strong single-thread performance and encryption capabilities, the AMD Ryzen AI 9 HX PRO 475 delivers. For desktop users running scientific, mathematical, or physics-based workloads, the Intel Core 9 273PE delivers higher scores in those specific tests. The multithread test is effectively a tie, so the decision rests on the workload split. AMD wins in scalar and memory-oriented tasks; Intel wins in arithmetic and physics tasks. The benchmark record does not indicate a single overall winner, only a clear division of strengths.
