AMD Ryzen AI 9 HX PRO 375 vs Intel Core i9-12900F Comparison

The Intel Core i9-12900F and AMD Ryzen AI 9 HX PRO 375 are separated by a mere 0.3% in average benchmark score, making them statistical equals in overall performance. However, the data reveals a clear division of labor: the Intel part wins 15 of 17 head-to-head tests, while the AMD chip takes only two, yet the AMD processor does so while operating at a dramatically lower thermal envelope and in a mobile form factor. The i9-12900F is the raw compute champion for desktop workloads, while the Ryzen AI 9 HX PRO 375 is the efficiency-focused mobile alternative that trades overall throughput for a much more portable package.

Where Each One Wins

The Intel Core i9-12900F dominates nearly every benchmark category, with its largest advantages in floating-point math and data encryption. In floating-point operations, the Intel chip scores 96,452 against the AMD's 74,626, a 29.2% lead that indicates a substantial edge in scientific computing, financial modeling, and other numerically intensive tasks. Data encryption shows an even wider gap at 19.2%, with the i9-12900F scoring 25,251 versus 21,186, suggesting stronger performance for security-related workloads and virtual private network processing.

The AMD Ryzen AI 9 HX PRO 375 wins only two tests, and both are narrow. It edges out the Intel chip in extended instructions with a score of 29,351 versus 28,265, a 3.7% advantage that points to better optimization for newer instruction set extensions. Its other win is in the PassMark physics test, scoring 1,843 against 1,842, a negligible 0.1% margin that is effectively a tie. These two victories indicate that the AMD part has specific strengths in modern instruction-heavy workloads, but they do not compensate for its losses elsewhere.

The Intel i9-12900F also wins the multithreaded tests by a consistent margin of 6.6% across Cinebench R15, R20, and R23, plus the PassMark multithread test. It scores 30,405 in Cinebench R23 multi-core versus the AMD's 28,529, cementing its position as the better choice for rendering, video encoding, and other parallel workloads. The single-threaded results are closer but still favor Intel, with a 2.6% lead in PassMark single-thread (4,017 vs 3,914) and a 6.6% lead in Cinebench R23 single-core (4,292 vs 4,027).

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i9-12900F uses the Alder Lake architecture on a 10 nm process from Intel's own foundry, featuring a 215 mm² die size. It employs a hybrid core layout with 16 cores and 24 threads, combining performance and efficiency cores to balance throughput against power consumption. The AMD Ryzen AI 9 HX PRO 375 uses the Zen 5 architecture, branded as Strix Point, built on TSMC's 4 nm process with a slightly larger 233 mm² die. It packs 12 cores and 24 threads, using a combination of Zen 5 and Zen 5c cores to maximize efficiency in a mobile envelope.

Cache configurations differ notably between the two. Both share the same 80 KB L1 cache per core, but the Intel chip has a larger 1.25 MB L2 per core versus the AMD's 1 MB per core. The L3 cache is where the gap widens: Intel provides 30 MB shared L3, while AMD offers only 16 MB. This difference in cache hierarchy contributes to the Intel chip's stronger performance in data-heavy workloads, though the AMD part compensates with higher memory bandwidth at 89.6 GB/s compared to Intel's 76.8 GB/s.

The memory support also diverges, with Intel supporting both DDR4 and DDR5 in a dual-channel configuration, while AMD supports DDR5 and LPDDR5X. Both support ECC memory, but the AMD chip includes integrated Radeon 890M graphics, whereas the Intel i9-12900F has no integrated graphics listed. The PCIe implementation differs as well, with Intel offering Gen 5 with 16 lanes and AMD limited to Gen 4 with 16 lanes, giving the Intel part an advantage for future high-bandwidth storage and graphics expansion.

Head-to-Head Benchmarks

The most decisive Intel victory comes in floating-point math, where the 29.2% lead is the largest margin in the entire comparison. This is followed by a 19.2% advantage in data encryption, demonstrating that the Intel architecture is significantly stronger in cryptographic operations. In integer math and data compression, the Intel chip wins by 8.4% in both categories, scoring 129,504 versus 119,521 and 451,402 versus 416,331 respectively.

The Cinebench results tell a consistent story of Intel superiority across all versions. In Cinebench R15 multi-core, Intel scores 3,064 against AMD's 2,875, a 6.6% margin that repeats exactly in R20 (12,770 vs 11,982) and R23 (30,405 vs 28,529). Single-core results follow the same pattern, with Intel leading by 6.7% in R15 (432 vs 405) and 6.6% in both R20 (1,802 vs 1,691) and R23 (4,292 vs 4,027). This consistency suggests a fundamental architectural advantage rather than a workload-specific quirk.

The AMD wins are narrow but real. Its 3.7% lead in extended instructions (29,351 vs 28,265) indicates that the Zen 5 architecture handles newer SIMD operations more efficiently. The physics test result is effectively a statistical dead heat, with AMD winning by just 0.1% (1,843 vs 1,842). The PassMark random string sorting test favors Intel by 6.9% (48,477 vs 45,358), while the single-thread tests show Intel ahead by 2.6% (4,017 vs 3,914 in both PassMark single-thread variants).

Specification Differences

The most striking difference is in thermal design power: the Intel i9-12900F has a 65W TDP while the AMD Ryzen AI 9 HX PRO 375 draws only 28W. This means the AMD chip delivers 89% of the Intel's average benchmark score (47,022 vs 47,176) while consuming less than half the power budget, proof of the efficiency of the 4 nm Zen 5 design. The Intel chip uses a 16-core, 24-thread configuration with a 2.40 GHz base clock and 5.10 GHz boost clock, while the AMD chip uses 12 cores with 24 threads, a 2.00 GHz base clock, and an identical 5.10 GHz boost clock.

The socket and platform targets are entirely different. Intel uses Socket 1700 for desktop systems, while AMD uses Socket FP8 for mobile laptops, reflecting their respective market segments. The Intel chip has an unlocked multiplier, allowing overclocking, while the AMD chip is locked. The release dates are separated by three years, with Intel launching on January 3, 2022, and AMD on January 5, 2025. The Intel chip carries a launch MSRP of $494, while the AMD chip has no listed launch price. The Intel part number is SRL4L, and the AMD part number is 100-000001683.

The Verdict

The Intel Core i9-12900F is the clear performance winner for desktop users who prioritize raw compute power. It leads in 15 of 17 benchmarks, with its most significant advantages in floating-point math (29.2%), data encryption (19.2%), and integer math (8.4%). Its larger 30 MB L3 cache, higher 65W TDP, and unlocked multiplier make it the better choice for rendering, scientific computing, and overclocking enthusiasts. The 6.6% consistent lead across all Cinebench versions confirms that this is not a fluke but a structural advantage in multi-threaded throughput.

The AMD Ryzen AI 9 HX PRO 375 is the better choice for mobile users who need desktop-class performance in a laptop form factor. Its 28W TDP delivers 89% of the Intel chip's average performance while consuming less than half the power, making it vastly more efficient. The 4 nm process and Zen 5 architecture provide better extended instruction handling and higher memory bandwidth, while the integrated Radeon 890M graphics eliminate the need for a discrete GPU in basic display tasks. Its wins in extended instructions and physics, though narrow, indicate that it is better optimized for newer software instruction sets.

The data shows that the choice between these two processors depends entirely on the target platform. Desktop builders should choose the Intel i9-12900F for its superior compute performance and PCIe Gen 5 support. Mobile buyers should choose the AMD Ryzen AI 9 HX PRO 375 for its efficiency and portability, accepting a small performance penalty in exchange for dramatically lower power consumption. The 0.3% difference in average scores means neither chip will disappoint, but each is optimized for a different environment.
