AMD Ryzen AI Max+ 392 vs Intel Core Ultra 5 245 Comparison

AMD Ryzen AI Max+ 392 vs Intel Core Ultra 5 245: the database pits a 12-core, 24-thread mobile flagship against a 14-core, 14-thread desktop part. The AMD chip, built on TSMC's 4 nm process, targets the mobile segment with a 55 W TDP, while Intel's Arrow Lake-S desktop processor uses a 3 nm process and a 65 W TDP. Benchmark results show a split: AMD wins 6 of the 11 recorded head-to-head tests, Intel wins 5, but the margins tell a more complex story about workload suitability.

Head-to-Head Benchmarks

The largest single victory for the AMD Ryzen AI Max+ 392 comes in PassMark integer math, where it scores 152414 against Intel's 91187, a 67.1% advantage. That is the defining gap of this comparison: the AMD part's simultaneous multithreading and larger shared L3 cache deliver massive throughput in integer-heavy calculations. Data compression follows a similar pattern, with AMD at 554760 versus 400942, a 38.4% lead. Extended instructions show AMD ahead by 37.1% (45666 vs 33304), confirming that the Zen 5 architecture handles complex instruction streams more efficiently. The multithread score of 45231 versus 38706 represents a 16.9% win, and physics simulation results put AMD at 2887 against 2569, a 12.4% margin. Random string sorting also favors AMD, 59487 to 49140, a 21.1% difference.

Intel's wins are concentrated in different areas. Floating point math is the clearest Intel victory: 120548 versus 99548, a 17.4% advantage. Single-thread performance shows Intel at 4394 versus 3927, a 10.6% lead in both recorded single-thread tests. Data encryption goes to Intel, 30236 versus 27784, an 8.1% margin. Prime number finding favors Intel, 365 versus 320, a 12.3% lead. Note that the Intel part does not have a PassMark multithread score that competes with AMD's 45231, but its 38706 result still places it within striking distance in heavily threaded workloads.

The average benchmark score tells a different story than the head-to-head wins. AMD's avgBenchmarkScore is 90541, putting it in the 96th percentile of all CPUs. Intel's avgBenchmarkScore is 48995, in the 90th percentile. The AMD chip's nearest rivals include the Intel Xeon 654 (avg 90717, delta -0.2%) and the AMD Ryzen 9 9955HX (avg 91199, delta -0.7%), meaning it sits just below those parts. The Intel Core Ultra 5 245's nearest rivals are the AMD Ryzen 7 PRO 5755G (avg 49196, delta -0.4%) and the AMD Ryzen 9 7900 (avg 49228, delta -0.5%). These percentile and rival data indicate that the AMD part competes in a higher performance tier overall, despite losing several individual tests.

Where Each One Wins

The AMD Ryzen AI Max+ 392 wins in workloads that scale with thread count and shared cache. Integer math, data compression, extended instructions, multithread performance, physics simulation, and random string sorting all favor AMD. The 64 MB shared L3 cache, combined with 24 threads across 12 cores, explains why compression and sorting tasks, which benefit from large working sets and parallel execution, show such strong results. The 67.1% integer math lead is the standout: this is the metric that separates the two parts most decisively.

The Intel Core Ultra 5 245 wins in floating point math, single-thread performance, encryption, and prime number finding. The 17.4% floating point advantage suggests the Arrow Lake architecture handles FP math more efficiently per clock. Single-thread performance at 4394 versus 3927 is a 10.6% margin, which matters for lightly threaded applications. Intel's 14 physical cores without hyperthreading (14 threads total) still manage to beat AMD in encryption, which often relies on dedicated instruction paths rather than raw thread count. Prime number finding is a latency-sensitive test, and Intel's higher boost clock of 5.10 GHz versus 5.00 GHz contributes to that 12.3% win.

The data shows a tradeoff: AMD for parallel integer and mixed workloads, Intel for scalar and floating point tasks. The physics result (AMD 2887 vs 2569) and multithread result (AMD 45231 vs 38706) confirm that AMD's threading model is more effective in sustained parallel execution. Intel's wins are narrower in aggregate; the sum of Intel's margins across its five wins is 58.7 percentage points, while AMD's six wins total 192.8 percentage points when adding the absolute delta values. Even excluding the outlier integer math result, AMD's wins average a larger margin.

The Verdict

The recorded data supports a clear split. The AMD Ryzen AI Max+ 392 is the stronger processor for multithreaded integer workloads, data compression, and physics simulation. Its 96th percentile ranking and average score of 90541 place it alongside workstation-class Xeon parts. The Intel Core Ultra 5 245, at the 90th percentile with an average of 48995, is the better choice for floating point math, single-thread performance, encryption, and prime number finding. A user running compression pipelines, integer-heavy compilation, or simulation code should favor AMD. A user running floating point analysis, single-threaded legacy applications, or encryption workloads should favor Intel. The 12-core, 24-thread AMD part with 64 MB L3 is a mobile processor, while the 14-core, 14-thread Intel part is a desktop chip with a 65 W TDP and a launch MSRP of $270. The AMD part has no recorded launch MSRP in the database. For raw average throughput, AMD leads by 84.8% (90541 vs 48995), but the Intel chip's single-thread and FP advantages should not be dismissed for the right workload mix.
