AMD Ryzen AI Max+ 388 vs Intel Core Ultra 7 270HX Plus Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the Intel Core Ultra 7 270HX Plus across every single benchmark in the head-to-head comparison. Of the 15 tests conducted, the Intel part claims all 15 wins, leaving the AMD Ryzen AI Max+ 388 without a single victory. This is not a close contest; the margins are substantial in nearly every category.

The largest gap appears in Cinebench R23 single-core, where the Intel chip scores 5917 against AMD's 1960, a difference of 66.9 percent. That is a massive per-thread advantage, and it carries over into multi-threaded workloads. In Cinebench R23 multi-core, the Intel processor posts 41913 versus 18759 for the AMD, a 55.2 percent deficit for the AMD part. Even in Cinebench R15, the older test suite, Intel leads by 32 percent in multi-core (4224 vs 2872) and by 50 percent in single-core (596 vs 298).

PassMark's floating-point math test shows a similar pattern. Intel scores 163567, while AMD manages 72722, a gap of 55.5 percent. The find prime numbers test is even more lopsided: Intel records 482, AMD only 145, a 69.9 percent difference. Physics testing also favors Intel heavily, 3843 versus 1843, a 52 percent margin.

The smallest deltas appear in integer math and single-threaded PassMark tests. In integer math, Intel leads 122449 to 109588, a 10.5 percent edge. In PassMark single-thread, Intel scores 4764 against AMD's 4185, a 12.2 percent advantage. Data compression shows Intel ahead by 18.7 percent (493179 vs 400887), while random string sorting favors Intel by 28 percent (60020 vs 43196). Extended instructions see Intel up 16.7 percent (39283 vs 32719), and data encryption shows a 46.9 percent Intel lead (37813 vs 20092). PassMark multithread sums up the picture: Intel at 48270, AMD at 33486, a 30.6 percent gap.

The average benchmark score confirms the overall hierarchy. Intel's average is 61834, placing it in the 93rd percentile among all CPUs. AMD's average is 49796, good for the 90th percentile. The nearest rivals for Intel are desktop-class parts like the Intel Core i9-13900KF (61841, a 0 percent delta) and the Intel Core i9-13900K (61766, a 0.1 percent delta). AMD's nearest rivals include the Intel Core 9 273PE (49845, a -0.1 percent delta) and the AMD Ryzen 9 7900 (49228, a 1.2 percent delta). The data places the Intel mobile chip in the same performance conversation as flagship desktop silicon from the previous generation.

The Verdict

Benchmark results indicate a clear performance hierarchy. The Intel Core Ultra 7 270HX Plus dominates the AMD Ryzen AI Max+ 388 in every measured workload, with margins ranging from 10.5 percent to 69.9 percent. Anyone selecting between these two on raw compute should choose the Intel part. The data leaves no ambiguity.

The AMD chip does hold a 90th percentile standing, which is respectable, but its average score of 49796 sits below Intel's 61834 by roughly 24 percent. The Intel part's nearest rivals are all high-end desktop CPUs, including the Intel Core i9-13900KF and the Intel Core i9-13900K, both of which score within 0.1 percent of it. AMD's nearest rivals are a mix of mobile and desktop parts, including the Intel Core 9 273PE and the AMD Ryzen 9 7900, but none of them approach the Intel Ultra 7 270HX Plus's score.

For users prioritizing single-thread performance, the Intel chip's 5917 in Cinebench R23 single-core is in a different tier from AMD's 1960. For multi-threaded rendering, Intel's 41913 versus AMD's 18759 is a 2.2x advantage. The Intel part also leads in every PassMark subtest, from integer math to data encryption. There is no workload category in the recorded data where the AMD processor wins, so the verdict is straightforward: the Intel Core Ultra 7 270HX Plus is the superior processor in this matchup.

Architecture Differences

The two processors take fundamentally different design approaches. The AMD Ryzen AI Max+ 388 uses 8 cores and 16 threads, built on a 4nm process at TSMC. Its architecture is Zen 5, codename Strix Halo, and it belongs to the Ryzen AI Max generation. The Intel Core Ultra 7 270HX Plus uses 20 cores and 20 threads, built on a 3nm process, also at TSMC. Its codename is Arrow Lake-HX Refresh, part of the Core Ultra Series 2 generation.

The core and thread counts explain much of the multi-threaded gap. Intel has 12 more physical cores, though it does not use simultaneous multithreading, so thread count equals core count at 20. AMD uses simultaneous multithreading, giving 16 threads from 8 cores. The Intel design's higher core count directly contributes to its large lead in Cinebench R23 multi-core and PassMark multithread tests.

Clock speeds also differ. AMD's base clock is 3.60 GHz with a boost of 5.00 GHz. Intel's base clock is lower at 2.40 GHz, but its boost reaches 5.30 GHz. The higher boost clock helps explain Intel's single-thread dominance in Cinebench R23 single-core and PassMark single-thread tests.

Cache layouts diverge significantly. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Intel's larger per-core caches likely contribute to its efficiency in single-threaded workloads, while AMD's larger shared L3 pool does not overcome the core count deficit.

Memory architecture favors AMD on bandwidth. AMD supports LPDDR5X with a quad-channel bus delivering 256.0 GB/s. Intel supports DDR5 with a dual-channel bus delivering 102.4 GB/s. AMD also supports ECC memory, while Intel does not. However, the benchmark data shows that AMD's memory bandwidth advantage does not translate into compute wins, likely because the Intel chip's core count and clock speed compensate.

PCIe connectivity favors Intel. Intel provides Gen 5 with 20 lanes, while AMD provides Gen 4 with 16 lanes. Both processors have integrated graphics: AMD uses Radeon 8060S, while Intel uses Arc Xe-LPG Graphics 64EU. The Intel part is multiplier unlocked, while AMD is not. Intel's die is 243 mm² with 17,800 million transistors, while AMD's die is listed as 2x 70.6 mm². Both target the mobile segment and are active in production. AMD released on 2026-01-05, and Intel released on 2026-03-16. Intel uses socket BGA 2114, AMD uses socket FP11.

Where Each One Wins

The recorded data shows no benchmark wins for the AMD Ryzen AI Max+ 388. Every test in the head-to-head comparison goes to the Intel Core Ultra 7 270HX Plus. That said, the use-case analysis can still differentiate the two based on the magnitude of the Intel wins and the architectural traits of each chip.

The Intel processor is the clear choice for compute-heavy tasks. Rendering, physics simulation, and floating-point math all favor it by wide margins. The 55.2 percent lead in Cinebench R23 multi-core and the 55.5 percent lead in PassMark floating-point math indicate strong performance for 3D rendering and scientific workloads. The 52 percent lead in PassMark physics points to solid performance in simulation tasks. Data encryption, where Intel leads by 46.9 percent, also favors the Intel part for security and compression workloads.

The Intel chip's single-thread advantage makes it suitable for lightly threaded applications. The 66.9 percent lead in Cinebench R23 single-core and the 50 percent lead in Cinebench R15 single-core suggest that legacy software and single-threaded productivity apps will run noticeably faster on Intel. The 12.2 percent lead in PassMark single-thread reinforces this.

The AMD processor does have attributes that could matter in specific system configurations. Its quad-channel LPDDR5X memory bus with 256.0 GB/s bandwidth is double Intel's dual-channel DDR5 at 102.4 GB/s. For workloads that are memory-bandwidth sensitive, such as large data transfers or certain integrated graphics tasks, AMD's platform offers more theoretical headroom. AMD also supports ECC memory, which matters for data integrity in professional environments. The Radeon 8060S integrated graphics may also be a differentiator, though the database does not include graphics benchmarks for this comparison.

However, these architectural advantages do not show up in the compute benchmarks. The data indicates that Intel's 20 cores, higher boost clock, and larger per-core caches outweigh AMD's memory bandwidth and ECC support. For users who prioritize raw CPU compute, the Intel Core Ultra 7 270HX Plus wins every measured category. For users who need ECC memory or a quad-channel memory bus, the AMD chip offers platform-level features that Intel does not, but the performance cost is substantial. The data supports choosing Intel for performance, with AMD only being relevant for specific platform requirements not covered by the benchmark suite.
