AMD Ryzen AI Max PRO 385 vs Intel Core i9-12900 Comparison

The AMD Ryzen AI Max PRO 385 and the Intel Core i9-12900 represent two distinct philosophies in processor design: a power-efficient, system-on-chip mobile part built around the Zen 5 architecture, and a high-core-count desktop part from the Alder Lake generation. The benchmark data reveals a fragmented competitive landscape where the winner is heavily workload-dependent, with the Intel part taking 12 benchmark wins to the AMD’s 5, yet the margin of victory in the AMD’s wins is often dramatic.

Head-to-Head Benchmarks

The most striking divergence between the two processors appears in the Cinebench suite, where results flip depending on the workload. In Cinebench R23 multi-core, the AMD Ryzen AI Max PRO 385 posts a score of 28424, which is 52.6% higher than the Intel Core i9-12900’s 18628. This is a massive victory for the 8-core/16-thread Zen 5 part over the 16-core/24-thread Intel chip. The single-core Cinebench R23 result is even more lopsided: the AMD scores 4012 against Intel’s 1825, a 119.8% delta. This suggests a fundamental advantage in per-thread instructions per clock for the Zen 5 architecture in this rendering workload.

However, the older Cinebench R20 and R15 versions tell a different story. In Cinebench R20 multi-core, the Intel part edges out a win with 11994 against the AMD’s 11938, a marginal 0.5% delta. The single-core R20 test is similarly close, with Intel winning 1693 to 1685, again by 0.5%. In Cinebench R15 multi-core, the Intel i9-12900 wins decisively with 3299 against 2865, a 13.2% advantage. The single-core R15 result, however, is a massive win for AMD: 404 to 262, a 54.2% lead. The data shows that the newer R23 test favors the AMD silicon, while the older tests can favor Intel, especially in multi-threaded scenarios.

The Passmark suite provides further granularity on specific computational tasks. The Intel Core i9-12900 demonstrates clear superiority in math-heavy workloads. It wins floating-point math with 91514 to the AMD’s 69580, a 24% lead. It also wins integer math with 127512 against 105056, a 17.6% advantage. Data encryption also favors Intel by a significant 18.2%, with scores of 23203 and 18978 respectively. The Intel part also takes data compression with 407899 versus 379448 (7% delta), random string sorting with 44070 versus 40784 (7.5% delta), and the overall multithread score with 33608 versus 32075 (4.6% delta). The physics test is nearly a tie, with Intel winning 1730 to 1711.

The AMD Ryzen AI Max PRO 385, on the other hand, excels in specific instruction-heavy and integer-prime workloads. It wins the Passmark extended instructions test with 31442 against Intel’s 24777, a 26.9% lead. It also wins the find prime numbers test with a score of 157 to 121, a 29.8% margin. In the single-thread Passmark tests, the result is effectively a statistical dead heat, with Intel winning 4003 to 3995, a negligible 0.2% delta. The data indicates that while Intel has a raw throughput advantage in many parallel tasks, the AMD part’s per-core capabilities are highly competitive in single-threaded contexts and superior in certain specialized instruction sets.

The Verdict

The data presents a clear case for the Intel Core i9-12900 being the stronger overall processor for raw multi-threaded throughput in legacy and math-heavy applications. It wins the majority of the head-to-head benchmark comparisons, including the Cinebench R20 and R15 multi-core tests and the majority of Passmark tests. Its 16 cores and 24 threads provide a physical advantage in workloads that scale linearly with core count, such as floating-point math and data encryption. The Intel part’s 10 nm process and dual-channel memory support are sufficient to feed its computational units for these tasks.

However, the AMD Ryzen AI Max PRO 385 is the unequivocal winner in the most modern rendering benchmark, Cinebench R23, and offers a staggering lead in single-core performance in both R23 and R15. The data suggests that for modern, well-optimized rendering engines and single-threaded applications, the AMD’s Zen 5 architecture is significantly more efficient. The 119.8% lead in single-core R23 is not a marginal difference; it is a generational leap in per-core capability. For users whose primary workload is the latest Cinebench version or applications that leverage similar instruction sets, the AMD part is the definitive choice. The overall average benchmark scores remain close—43326 for AMD and 42906 for Intel—but the distribution of wins is more telling than the average. The Intel part is the safer bet for broad multi-threaded performance, while the AMD part is the specialist for modern single-core and particular multi-core workloads.

Where Each One Wins

The Intel Core i9-12900 is the clear winner for users running heavily multi-threaded, parallelized applications that are not reliant on the newest instruction sets. The data shows it is superior in data compression, encryption, integer math, floating-point math, and random string sorting. This makes it a strong candidate for file archiving, database work, financial modeling, and scientific computing that uses older codebases. Its victory in Cinebench R20 and R15 multi-core also suggests it remains a viable option for rendering with older software versions. The high core count directly translates to wins in these scenarios, making it the workhorse for throughput-oriented tasks.

The AMD Ryzen AI Max PRO 385 wins where the instruction set and architecture matter more than raw core count. Its dominance in Cinebench R23, both single and multi-core, points to its strength in the latest rendering workloads. The 52.6% lead in multi-core R23 shows that its 8 Zen 5 cores can outperform Intel’s 16 Alder Lake cores in this specific test, likely due to superior IPC and memory bandwidth from its quad-channel LPDDR5X support. The win in extended instructions and prime number finding makes it suitable for cryptography, simulation, and certain types of scientific calculations. Its single-core performance in R15 and R23 makes it ideal for lightly-threaded applications like legacy games or specific productivity tools where per-thread speed is critical.
