AMD Ryzen AI Max+ 392 vs Intel Core Ultra 5 225F Comparison

AMD Ryzen AI Max+ 392 vs Intel Core Ultra 5 225F

The AMD Ryzen AI Max+ 392 and Intel Core Ultra 5 225F occupy different corners of the processor market, one a mobile-focused part with a hefty 55W TDP and the other a desktop chip at 65W. The recorded data shows a clear split: the AMD part wins 8 of 11 head-to-head benchmarks, while the Intel chip takes 3, including both single-thread tests. The AMD processor sits at the 96th percentile among all CPUs, while the Intel part lands at the 85th percentile, a gap that reflects their divergent design goals and benchmark strengths.

Head-to-Head Benchmarks

The most decisive victory for the AMD Ryzen AI Max+ 392 comes in integer math, where it scores 152414 against the Intel Core Ultra 5 225F's 66417, a 129.5% advantage. This is the largest delta in the entire comparison and indicates a substantial throughput advantage for heavily parallel integer workloads. Data compression also favors AMD heavily, with a score of 554760 versus 310843, a 78.5% lead. Extended instructions show a 62.9% gap in AMD's favor, with scores of 45666 against 28027. Random string sorting follows the same pattern, AMD at 59487 versus Intel's 37325, a 59.4% difference.

Multithreaded performance, as measured by PassMark, gives AMD a 45.9% win, scoring 45231 against 31004. The physics test shows a smaller but still clear AMD advantage, 2887 versus 2430, an 18.8% delta. Data encryption goes to AMD at 27784 versus 22648, a 22.7% margin. Floating point math is the closest AMD win, 99548 against 92554, a 7.6% edge.

The Intel Core Ultra 5 225F takes the single-thread tests decisively. In passmark_single_thread, Intel scores 4397 against AMD's 3927, a 10.7% lead. The duplicate singlethread test shows the same result. Intel also wins the prime number finding test, scoring 352 versus AMD's 320, a 9.1% advantage. These three wins are the only ones for Intel in the head-to-head data, and they all point to per-core clock speed and single-thread efficiency rather than raw core count.

Architecture Differences

The AMD Ryzen AI Max+ 392 uses the Zen 5 architecture on a 4 nm TSMC process, with a die size listed as 2x 70.6 mm². It packs 12 cores and 24 threads, enabled by simultaneous multithreading. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3. Memory support is LPDDR5X over a quad-channel bus, yielding 256.0 GB/s of bandwidth. It also supports ECC memory. The integrated graphics are a Radeon 8060S, and the socket is AMD Socket FP11, which indicates a mobile or embedded platform.

The Intel Core Ultra 5 225F is built on Arrow Lake architecture, fabricated on a 3 nm TSMC process. It has 10 cores and 10 threads, so no hyperthreading. The die is a single 243 mm² piece with 17,800 million transistors. Cache is larger per core: 192 KB of L1 and 3 MB of L2, but the shared L3 is only 20 MB. Memory support is DDR5 over a dual-channel bus, providing 102.4 GB/s of bandwidth. It does not support ECC memory and has no integrated graphics. It uses Intel Socket 1851 and PCIe Gen 5 with 20 lanes, compared to AMD's PCIe Gen 4 with 16 lanes.

The process node difference, 4 nm versus 3 nm, is notable, but the AMD part compensates with more cores, threads, and a much larger L3 cache. The memory bandwidth gap is extreme: 256.0 GB/s versus 102.4 GB/s, a factor of 2.5 in AMD's favor, which likely drives many of the benchmark deltas in data-heavy tests. The Intel part has a higher base clock, 3.30 GHz versus 3.20 GHz, and a slightly lower boost clock, 4.90 GHz versus 5.00 GHz.

Where Each One Wins

The AMD Ryzen AI Max+ 392 dominates every multithreaded and parallel workload in the measured data. Data compression, encryption, extended instructions, integer math, multithread, physics, random string sorting, and floating point math all go to AMD, with deltas ranging from 7.6% to 129.5%. This is a processor built for throughput, and the benchmark results confirm it. The 12 cores with SMT, combined with the massive L3 cache and quad-channel memory bandwidth, deliver consistently higher scores in tasks that can use all available execution resources. The 96th percentile ranking among all CPUs reinforces this positioning.

The Intel Core Ultra 5 225F wins where the workload is light on parallelism and dependent on per-core speed. Single-thread performance is 10.7% better than AMD, and prime number finding, which is often latency-bound, is 9.1% faster. These results indicate a strong core design with efficient clock behavior. The desktop market segment and lack of integrated graphics suggest this is meant for systems with a discrete GPU, where the CPU handles gaming and general tasks rather than compute-heavy rendering or data processing. The 85th percentile still puts it above most CPUs, but the delta to AMD's percentile is significant.

Specification Differences

The two processors differ on nearly every major specification. The AMD Ryzen AI Max+ 392 has 12 cores and 24 threads, while the Intel Core Ultra 5 225F has 10 cores and 10 threads. Base clocks are close, 3.20 GHz versus 3.30 GHz, but boost clocks differ, 5.00 GHz versus 4.90 GHz. TDP is 55W for AMD and 65W for Intel, despite AMD being a mobile part and Intel a desktop part.

Socket and platform are completely different: AMD uses Socket FP11, Intel uses Socket 1851. Architecture and codename differ, Zen 5 (Strix Halo) versus Arrow Lake (Arrow Lake-S). Process node favors Intel at 3 nm versus AMD's 4 nm, and Intel lists a transistor count of 17,800 million, a figure AMD does not provide. Die size is 2x 70.6 mm² for AMD versus 243 mm² for Intel.

Cache organization is markedly different. AMD provides 80 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3. Intel provides 192 KB L1 per core, 3 MB L2 per core, and 20 MB shared L3. Memory support and bandwidth are a major differentiator: LPDDR5X quad-channel at 256.0 GB/s for AMD versus DDR5 dual-channel at 102.4 GB/s for Intel. AMD supports ECC, Intel does not. PCIe lanes and generation differ, Gen 4 16 lanes versus Gen 5 20 lanes. Integrated graphics are present on AMD (Radeon 8060S) but listed as N/A on Intel. Release dates differ, with AMD launching on 2026-01-05 and Intel on 2025-01-06. The Intel part has a launch MSRP of $231; AMD has no listed MSRP. Market segments are Mobile for AMD and Desktop for Intel.

The Verdict

The data points to two distinct use cases. The AMD Ryzen AI Max+ 392 is the clear choice for workloads that scale across cores and memory bandwidth. Its 129.5% lead in integer math and 78.5% lead in data compression, along with wins in encryption, extended instructions, multithread, physics, random string sorting, and floating point math, make it the superior processor for data processing, compilation, scientific computing, and any parallel task. The 64 MB L3 cache and 256.0 GB/s memory bandwidth feed the 12 cores effectively, and the 96th percentile ranking confirms its position among the top CPUs.

The Intel Core Ultra 5 225F is the better option for single-threaded and latency-sensitive tasks. A 10.7% single-thread advantage and a 9.1% win in prime number finding indicate stronger per-core performance, which benefits everyday desktop responsiveness, many games, and lightly threaded applications. The 85th percentile is respectable, and the desktop form factor with no integrated graphics suggests pairing with a discrete GPU. However, the benchmark gaps are massive in AMD's favor across the board, and the Intel chip cannot match the AMD part's aggregate throughput.

For a system builder prioritizing maximum compute density and memory bandwidth, the AMD Ryzen AI Max+ 392 is the data-backed choice. For a desktop user who values single-thread speed and already has a discrete GPU, the Intel Core Ultra 5 225F offers a different trade-off, but the recorded scores show it falls behind in most measured categories. The choice comes down to workload: parallel and memory-heavy favors AMD, single-thread and low-latency favors Intel.
