AMD Ryzen AI Max PRO 380 vs Intel Core i9-12900F Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in this matchup. The Intel Core i9-12900F wins all 11 head-to-head benchmark comparisons, though the margin varies dramatically by workload. The most lopsided result is in floating point math, where Intel scores 96,452 against AMD's 53,084, a 45% advantage. Integer math tells a similar story: Intel posts 129,504 versus 79,789, a 38.4% gap. These are not marginal differences; they represent fundamental throughput advantages in raw arithmetic workloads.

Data compression favors Intel heavily as well. The Core i9-12900F manages 451,402 in PassMark data compression against 293,595 for the Ryzen AI Max PRO 380, a 35% deficit for the AMD part. Encryption is even worse for AMD, with Intel winning 25,251 to 14,502, a 42.6% gap. The pattern is consistent: every heavily multithreaded workload shows Intel ahead by double digits.

The closest contest is single-thread performance. Intel scores 4,017 in PassMark single-thread against 3,995 for AMD, a razor-thin 0.5% edge. This is effectively a tie; the database records the Intel chip as the winner, but the measured difference is within noise for most real-world applications. Anyone choosing between these two for lightly threaded tasks should not base the decision on this metric.

Multithread performance, as measured by PassMark, gives Intel a 32.5% lead: 35,912 versus 24,244. Physics simulation shows a 39.2% gap in Intel's favor, 1,842 to 1,120. Random string sorting goes to Intel by 35.7%, 48,477 to 31,153. Extended instructions favor Intel by 13.9%, 28,265 to 24,333, the smallest double-digit margin in the set. Prime number finding shows Intel at 127 against 75, a 40.9% advantage.

Average benchmark scores place the AMD part at 48,171 and the Intel part at 47,176, meaning the AMD chip actually holds a 2.1% higher average across its recorded benchmark suite. This apparent contradiction resolves when you consider the benchmark sets differ between the two processors. The Intel chip's PassMark results are consistently strong, but its Cinebench scores (multi-core 30,405 in R23, single-core 4,292 in R23) and Geekbench scores (15,965 multi, 2,339 single) are included in its average. The AMD part's average is built from a more uniform PassMark-heavy set. The head-to-head data, where both chips run identical tests, is the more reliable comparison.

In the nearest rivals table, the AMD Ryzen AI Max PRO 380 sits within 0.5% of several strong parts: it trails the Intel Core Ultra 5 245HX by 0.2% in average score, matches the Intel Core Ultra 5 235A at a 0.1% deficit, and edges the AMD Ryzen 9 3900 by 0.5%. The Intel Core i9-12900F likewise sits in a tight cluster, trailing the Intel Core i7-13700KF by 0.3% and the Intel Core Ultra X9 378H by 0.6%, while leading the AMD Ryzen AI 9 HX PRO 375 by 0.3%. Both chips occupy the 89th to 90th percentile among all CPUs in the database.

Architecture Differences

The two processors come from opposite design philosophies. The AMD Ryzen AI Max PRO 380 uses Zen 5 architecture on a 4 nm TSMC process, codenamed Strix Halo. It is built for the mobile segment on AMD Socket FP11. The Intel Core i9-12900F uses Alder Lake architecture on Intel's 10 nm process, codenamed Alder Lake-S, and targets desktop systems on Socket 1700.

Core counts differ sharply. AMD fields 6 cores and 12 threads; Intel fields 16 cores and 24 threads. That 10-core and 12-thread deficit explains most of the multithread benchmark gaps. Clock speeds partially compensate: AMD runs a 3.60 GHz base and 4.90 GHz boost, while Intel runs a 2.40 GHz base and 5.10 GHz boost. The higher Intel boost clock helps in single-thread work, though the measured single-thread gap is only 0.5%.

Cache hierarchies diverge in capacity and organization. Both use 80 KB of L1 per core. AMD uses 1 MB of L2 per core versus Intel's 1.25 MB per core. The shared L3 is where Intel pulls ahead: 30 MB shared versus AMD's 16 MB shared. For workloads that fit in L3, the Intel chip holds nearly twice the working set.

Memory support differs by platform. AMD supports only LPDDR5X with a dual-channel bus, delivering 128.0 GB/s of memory bandwidth. Intel supports both DDR4 and DDR5 on a dual-channel bus, with a rated bandwidth of 76.8 GB/s. The AMD part's bandwidth advantage (about 67% higher) does not translate into benchmark wins in the recorded tests, which suggests the workloads measured are compute-bound rather than memory-bandwidth-bound. Both chips support ECC memory.

PCIe connectivity also differs. AMD provides Gen 4 with 16 CPU lanes; Intel provides Gen 5 with 16 CPU lanes. The Intel platform offers newer PCIe signaling, though the practical impact depends on the devices attached. The AMD chip includes integrated Radeon 8040S graphics; the Intel Core i9-12900F has no integrated graphics, requiring a discrete GPU for display output.

Power envelopes favor AMD on paper: 55 W versus 65 W. The Intel chip also has an unlocked multiplier, making overclocking possible, while the AMD part is locked. Production status for both is listed as active. The Intel part launched in January 2022 with a launch MSRP of $494; the AMD part launched in January 2025 with no recorded launch MSRP.

The Verdict

The data points to a clear split by use case. If the workload is heavily multithreaded, the Intel Core i9-12900F is the stronger processor in every recorded measurement. Its 16 cores and 24 threads, paired with 30 MB of shared L3, deliver leads of 32.5% in multithread, 45% in floating point math, and 38.4% in integer math. For rendering, physics simulation, data compression, or encryption, the Intel chip is the choice. The 13.9% lead in extended instructions also suggests better performance in vectorized code.

If the workload is lightly threaded, the decision is less clear. The 0.5% single-thread gap is negligible, so other factors should dominate: the AMD chip's integrated graphics, its 55 W power envelope, and its mobile platform. The AMD part also has higher memory bandwidth at 128.0 GB/s, which could matter for specific memory-heavy tasks even if the recorded benchmarks do not show it.

The AMD chip's nearest rivals include the Intel Core Ultra 5 245HX and the AMD Ryzen 9 7900X3D, all within 0.5% in average score. The Intel chip's rivals include the Intel Core i7-13700KF and the AMD Ryzen AI 9 HX PRO 375, also within 0.6%. Both chips are competitive within their respective segments, but they are not competing for the same buyer.

Where Each One Wins

The Intel Core i9-12900F wins every head-to-head benchmark in the database. Its largest margins come in floating point math (45% ahead), data encryption (42.6% ahead), and prime number finding (40.9% ahead). It also leads in physics simulation by 39.2%, integer math by 38.4%, random string sorting by 35.7%, data compression by 35%, multithread by 32.5%, and extended instructions by 13.9%. The Intel chip is the pick for anyone running compute-heavy desktop workloads: rendering, scientific computing, video encoding, large-scale data processing, or any parallel workload that can use 24 threads.

The AMD Ryzen AI Max PRO 380 has no benchmark wins in this comparison. Its strengths are contextual rather than measured: integrated Radeon 8040S graphics eliminate the need for a discrete GPU, the 55 W TDP suits compact mobile systems, and the 128.0 GB/s memory bandwidth is the higher figure between the two. For a mobile workstation or a small-form-factor build where the GPU is already sufficient and power draw matters, the AMD part is the more sensible platform choice despite losing every compute benchmark. Its single-thread score of 3,995 is effectively tied with Intel's 4,017, so daily desktop responsiveness should be similar. The AMD chip also holds a higher average benchmark score overall (48,171 versus 47,176) and a 90th percentile ranking versus Intel's 89th, though this reflects different benchmark suites rather than superiority in shared tests.

Choose Intel when raw multithreaded compute is the priority and a discrete GPU is already in the system. Choose AMD when the platform needs integrated graphics, lower power draw, higher memory bandwidth, or a mobile form factor, and when the multithread deficit is acceptable.
