AMD Ryzen AI Max+ 388 vs Intel Core 9 270H Comparison

Head-to-Head Benchmarks

The benchmark data records a decisive overall victory for the AMD Ryzen AI Max+ 388, which claims 12 of the 15 head-to-head comparisons. The Intel Core 9 270H wins only 3 tests, but those wins are concentrated in single-core and physics workloads, showing a distinct performance split between the two processors.

The largest single delta appears in PassMark extended instructions, where the AMD part scores 32719 against Intel's 20079, a 63% advantage. This is the single biggest gap in the entire comparison, indicating a major difference in SIMD or specialized instruction throughput. The data compression test also shows a substantial lead for AMD: 400887 versus 333785, a 20.1% difference. The AMD processor also delivers a 29.5% lead in prime number finding (145 versus 112) and a 17.2% advantage in random string sorting (43196 versus 36867).

Multi-core rendering tests confirm the AMD lead, though the margins are more moderate. In Cinebench R23 multi-core, AMD scores 18759 versus Intel's 18000, a 4.2% edge. The older Cinebench R15 multi-core test shows a much larger gap: 2872 versus 2464, a 16.6% advantage for AMD. PassMark multi-thread performance also favors AMD at 33486 versus 28764, a 16.4% difference. Integer math goes to AMD by 12.2% (109588 versus 97654), while floating point math is closer at 2.9% (72722 versus 70640). Data encryption is comparatively tight, with AMD ahead by 3.7% (20092 versus 19369).

The Intel Core 9 270H takes the single-core crowns. In Cinebench R15 single-core, Intel scores 347 against AMD's 298, a 14.1% advantage. Cinebench R23 single-core also goes to Intel: 2040 versus 1960, a 3.9% edge. The third Intel win is PassMark physics, where Intel records 1966 against AMD's 1843, a 6.3% margin. However, the PassMark single-thread test goes the other way: AMD scores 4185 versus Intel's 3944, a 6.1% lead. This mixed single-thread picture suggests the Intel part has strong legacy single-core performance in Cinebench, while AMD holds the advantage in the PassMark single-thread metric.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen AI Max+ 388 is built on the Zen 5 architecture with the Strix Halo codename, fabricated on a 4 nm process by TSMC. The Intel Core 9 270H uses the Raptor Lake architecture, specifically the Raptor Lake-H refresh, on Intel's 10 nm process. These process differences partly explain the power and efficiency profiles, with AMD on the smaller node.

Core counts differ significantly. The Intel part has 14 cores and 20 threads, while the AMD part has 8 cores and 16 threads. Despite having fewer cores and threads, the AMD processor wins the multi-threaded benchmarks, which indicates that its Zen 5 cores deliver substantially more work per thread. The Intel processor compensates for lower per-core efficiency with more physical cores.

Cache hierarchies also differ. Both processors have 80 KB of L1 per core. The AMD part has 1 MB of L2 per core and 32 MB of shared L3. The Intel part has 2 MB of L2 per core and 24 MB of shared L3. The Intel design doubles the per-core L2, while AMD offers a larger shared L3 pool.

Memory architecture is a major differentiator. AMD uses LPDDR5X with a quad-channel memory bus and 256.0 GB/s of bandwidth. Intel supports both DDR4 and DDR5 with a dual-channel bus, and no bandwidth figure is recorded for the Intel part. The AMD memory subsystem delivers substantially more bandwidth on paper, and the recorded benchmark results are consistent with that advantage. AMD also supports ECC memory, while Intel does not.

PCIe connectivity differs as well. AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 8 lanes (CPU only). The Intel part has a faster PCIe generation but fewer lanes. Integrated graphics also differ: AMD pairs the processor with a Radeon 8060S, while Intel uses Iris Xe Graphics with 96 execution units.

Clock speeds favor Intel on boost. The Intel part has a base clock of 2.70 GHz and a boost clock of 5.80 GHz. The AMD part has a base clock of 3.60 GHz and a boost clock of 5.00 GHz. AMD starts higher but Intel boosts higher. The TDP rating is 55 W for AMD and 45 W for Intel, though the actual power behavior depends on platform limits.

Where Each One Wins

The AMD Ryzen AI Max+ 388 wins in workloads that stress sustained multi-threaded throughput, data movement, and specialized instruction execution. The Cinebench R23 and R15 multi-core results, the PassMark multi-thread score, and the integer math result all point to a processor that handles parallel compute with high efficiency. The 63% lead in extended instructions is particularly relevant for workloads that use AVX-512 or similar instruction sets, though the database does not specify the exact instruction mix.

The data compression result (20.1% lead) and random string sorting (17.2% lead) indicate that the AMD part handles memory-intensive and branch-heavy workloads well. The 256.0 GB/s memory bandwidth and quad-channel LPDDR5X support likely contribute to these wins, as does the larger 32 MB shared L3 cache. The AMD part also wins PassMark single-thread by 6.1%, so it is not purely a multi-core specialist.

The Intel Core 9 270H wins in Cinebench single-core tests, with a 14.1% lead in R15 single-core and a 3.9% lead in R23 single-core. These are legacy rendering benchmarks, and the Intel part's 5.80 GHz boost clock likely drives that advantage. The PassMark physics win (6.3%) suggests the Intel part handles certain physics simulation workloads better, which may relate to its higher boost frequency or different scheduling behavior.

The overall picture is that AMD dominates the majority of recorded workloads, while Intel retains an edge in specific single-threaded rendering scenarios and physics. The AMD part's 90th percentile ranking across all CPUs versus Intel's 86th percentile confirms the overall positioning from the benchmark aggregate.

The Verdict

The recorded data points to the AMD Ryzen AI Max+ 388 as the stronger processor for the majority of measured workloads. It wins 12 of 15 head-to-head tests, including all of the multi-threaded rendering benchmarks, all of the PassMark math tests, data compression, encryption, extended instructions, prime number finding, random string sorting, and PassMark single-thread. Its 90th percentile ranking across all CPUs exceeds the Intel part's 86th percentile. The average benchmark score of 49796 for AMD versus 38335 for Intel reflects a 29.9% aggregate advantage.

The Intel Core 9 270H is the better choice only for workloads that specifically benefit from its Cinebench single-core wins and physics performance. The 14.1% lead in Cinebench R15 single-core and the 6.3% lead in PassMark physics are real advantages, but they cover a narrow slice of the recorded test suite. The Intel part also has a higher boost clock at 5.80 GHz versus 5.00 GHz, and it supports PCIe Gen 5, which may matter for certain storage or external GPU configurations.

For users prioritizing multi-threaded compute, data compression, encryption, or specialized instruction throughput, the AMD part is the clear selection based on the benchmark evidence. For users who need maximum legacy single-core rendering performance or physics simulation, the Intel part has a narrower but measurable edge. The AMD processor also offers ECC memory support and a higher TDP envelope of 55 W versus 45 W, which may factor into platform decisions. The Intel part has a launch MSRP of $697.
