AMD Ryzen AI Max+ 388 vs Intel Core Ultra 5 235H Comparison

# AMD Ryzen AI Max+ 388 vs Intel Core Ultra 5 235H

The benchmark database records 15 head-to-head tests between these two mobile processors, and the results split sharply by workload type. The Intel Core Ultra 5 235H wins 9 tests, while the AMD Ryzen AI Max+ 388 wins 6. However, the AMD chip's victories are often by larger margins, particularly in integer-heavy and compression workloads, while the Intel chip's wins are concentrated in single-threaded and floating-point tasks. The overall average benchmark score tells a different story: the AMD Ryzen AI Max+ 388 posts 49796 versus 37522 for the Intel part, a gap that reflects the AMD chip's dominance in the PassMark suite's aggregate metrics.

Where Each One Wins

The AMD Ryzen AI Max+ 388 is the clear choice for data-heavy and integer-processing workloads. Its 32.8% advantage in data compression (400887 versus 301979) and 47.6% lead in integer math (109588 versus 74247) show that the Zen 5 architecture handles algorithmic and sorting tasks with far greater efficiency. The chip also wins in extended instructions by 40.1% (32719 versus 23354), multithread by 11.3% (33486 versus 30091), and random string sorting by 19.3% (43196 versus 36208). These results indicate a processor optimized for database operations, encryption-adjacent processing, and general productivity workloads that rely on parallel integer execution.

The Intel Core Ultra 5 235H counters with wins in single-threaded performance and floating-point math. Its single-thread score of 4359 beats the AMD's 4185 by 4%, and its Cinebench R23 single-core score of 3613 demolishes the AMD's 1960 by 45.8%. The Intel chip also leads in floating-point math by 22.2% (93509 versus 72722) and in find prime numbers by 39.3% (239 versus 145). These results point to a processor that excels in scientific computing, physics simulations, and any workload that relies heavily on scalar or floating-point execution per core.

Architecture Differences

The two processors diverge fundamentally in design philosophy. The AMD Ryzen AI Max+ 388 uses 8 cores and 16 threads based on Zen 5 architecture, built on a 4 nm TSMC process. It features 80 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The memory subsystem is a quad-channel LPDDR5X interface delivering 256.0 GB/s of bandwidth, and it supports ECC memory. The integrated graphics is a Radeon 8060S, and the PCIe interface is Gen 4 with 16 lanes.

The Intel Core Ultra 5 235H uses 14 cores but only 14 threads, meaning it lacks hyperthreading on any of its cores. It is built on Arrow Lake architecture using a 3 nm TSMC process, with 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3 cache. Memory support covers DDR5 and LPDDR5X through a dual-channel interface with 102.4 GB/s bandwidth, roughly 60% less than the AMD part. ECC is not supported. The integrated graphics is Arc Graphics 140T, and the PCIe interface is Gen 5 with 8 lanes.

The process node difference (4 nm versus 3 nm) gives Intel a manufacturing edge, but the AMD chip's larger cache hierarchy and quad-channel memory clearly influence its superior throughput in memory-bound and multithreaded integer workloads. The Intel chip's higher core count (14 versus 8) does not translate into more threads, and its dual-channel memory limits parallel data movement.

Head-to-Head Benchmarks

The largest single victory in the entire comparison belongs to the AMD Ryzen AI Max+ 388 in PassMark integer math, where it scores 109588 against 74247, a 47.6% advantage. This is a decisive margin that suggests the Zen 5 cores execute integer operations at a fundamentally higher rate per clock, likely aided by the quad-channel memory feeding data faster. Similarly, extended instructions show a 40.1% lead (32719 versus 23354), confirming that the AMD chip handles SIMD and specialized instruction sets more efficiently.

The Intel Core Ultra 5 235H's biggest win is in Cinebench R23 single-core, where it scores 3613 versus 1960, a 45.8% lead. This is a striking result because both chips boost to 5.00 GHz, yet the Intel architecture delivers nearly double the single-core Cinebench score. The same pattern appears in Cinebench R15 single-core, where Intel leads by 18.1% (364 versus 298). These numbers indicate that Intel's Arrow Lake cores have a significantly higher instructions-per-clock advantage in rendering and 3D modeling tasks.

In multicore Cinebench R23, the Intel chip wins by 26.7% (25598 versus 18759), despite having fewer threads. This suggests that the Intel cores scale better in rendering workloads, even with 14 threads versus 16. However, in the PassMark multithread test, the AMD chip wins by 11.3% (33486 versus 30091), showing that the AMD processor excels in different types of parallel workloads. The Cinebench tests emphasize floating-point and cache-sensitive operations, while PassMark multithread covers a broader mix.

Data compression is another AMD stronghold, with a 32.8% lead (400887 versus 301979). Random string sorting follows with 19.3% (43196 versus 36208). These are memory-intensive tests, and the AMD chip's 256.0 GB/s bandwidth versus 102.4 GB/s likely explains the gap. Conversely, Intel wins in data encryption by 13.1% (23121 versus 20092) and in physics by 7.2% (1985 versus 1843), suggesting that the Intel architecture handles certain cryptographic and physics calculations more efficiently.

The Verdict

The data indicates two distinct usage profiles. The AMD Ryzen AI Max+ 388 is the stronger choice for data compression, integer math, extended instructions, and multithreaded PassMark workloads, with margins between 11.3% and 47.6%. Its quad-channel memory and 256.0 GB/s bandwidth make it suited for database processing, data analytics, and any workload that moves large volumes of data through the processor. The 90th percentile ranking and average score of 49796 place it in the upper tier of all recorded CPUs, close to the Intel Core 9 273PE (delta of -0.1%) and ahead of the Intel Core i5-14600KF (delta of 0.8%).

The Intel Core Ultra 5 235H is the better processor for single-threaded performance and floating-point workloads. Its Cinebench R23 single-core score of 3613 is 45.8% higher, and its floating-point math advantage is 22.2%. The 85th percentile ranking and average score of 37522 place it near the Intel Core i9-13900HK (delta of 0.3%) and the Intel Core i5-13600K (delta of -0.4%). For users running rendering, physics simulation, or scientific calculations that rely on scalar performance, the Intel chip delivers superior results.

The 14-core versus 8-core count does not decide the comparison. The AMD chip wins the PassMark multithread test despite having fewer cores, while the Intel chip wins Cinebench R23 multicore despite having fewer threads. The deciding factor is workload type, not core count. The AMD chip also offers ECC support and more PCIe lanes (16 versus 8), while the Intel chip uses the newer PCIe Gen 5 standard. Both processors boost to 5.00 GHz, but the Intel chip has a lower base clock of 2.40 GHz versus 3.60 GHz, and a lower TDP of 28 watts versus 55 watts.
