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

The AMD Ryzen AI Max+ 388 and Intel Core Ultra 5 235T are two very different processors, one a mobile-focused part with a powerful integrated GPU and the other a desktop chip aimed at mainstream workloads. The benchmark data reveals a clear split: Intel wins the majority of tests with 9 wins to AMD's 6, but AMD's victories are often by large margins in specialized tasks. The Intel Core Ultra 5 235T delivers significantly higher single-thread performance and dominates in rendering, while the AMD Ryzen AI Max+ 388 excels in data compression, integer math, and extended instruction workloads. The average benchmark score for the AMD part is 49,796, placing it in the 90th percentile of all CPUs, while the Intel chip scores 38,561 on average, sitting in the 86th percentile. This overall gap, however, masks the fact that each processor has distinct strengths that make it suitable for different use cases.

Head-to-Head Benchmarks

The largest single-thread performance gap is found in Cinebench R23 single-core testing. The Intel Core Ultra 5 235T scores 3,703 points, while the AMD Ryzen AI Max+ 388 manages 1,960 points, giving Intel a commanding 47.1% advantage. This is a massive margin that will translate directly into responsiveness for lightly-threaded applications. The same pattern appears in Cinebench R15 single-core, where Intel wins 373 to 298, a 20.1% difference. Even in PassMark's single-thread test, Intel leads, scoring 4,339 versus AMD's 4,185, though the margin is much smaller at 3.5%.

Multi-threaded rendering tells a more nuanced story. In Cinebench R23 multi-core, the Intel Core Ultra 5 235T takes a decisive win with 26,232 points against AMD's 18,759, a 28.5% lead. However, in Cinebench R15 multi-core, the AMD Ryzen AI Max+ 388 comes out ahead, scoring 2,872 versus Intel's 2,644, an 8.6% advantage. This discrepancy suggests that the Intel chip scales better with the longer, more sustained workload of Cinebench R23, while AMD's shorter-burst performance in R15 is superior.

PassMark's integer math test shows AMD's strength, with the Ryzen AI Max+ 388 scoring 109,588 against Intel's 84,244, a 30.1% lead.

The AMD Ryzen AI Max+ 388, despite its lower average benchmark score, is the stronger option for tasks involving data compression, integer math, and extended instruction sets. Its 35.8% lead in data compression and 30.1% lead in integer math indicate that it handles database operations and general arithmetic workloads more efficiently. The AMD part also wins the Cinebench R15 multi-core test, showing that it can deliver strong burst performance.

For a desktop user who needs a balanced processor for everyday tasks, office work, and occasional gaming, the Intel Core Ultra 5 235T offers better single-thread performance, which is the more important metric for most consumer software. The AMD Ryzen AI Max+ 388, being a mobile processor with a 55 watt TDP, appears optimized for a different set of priorities, particularly in scenarios where its integrated graphics and specialized compute capabilities are beneficial.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Max+ 388 uses the Zen 5 architecture, codenamed Strix Halo, built on a 4 nm process from TSMC. It is a mobile processor designed for AMD Socket FP11. The Intel Core Ultra 5 235T uses the Arrow Lake architecture, codenamed Arrow Lake-S, built on a 3 nm process, also from TSMC. Intel's chip is a desktop processor using Intel Socket 1851.

The core configurations differ significantly. The AMD Ryzen AI Max+ 388 has 8 cores and 16 threads, meaning each core supports two threads via simultaneous multithreading. The Intel Core Ultra 5 235T has 14 cores but only 14 threads, indicating that it does not use hyper-threading in this configuration. This explains why Intel can win multi-core tests despite having fewer threads, as its individual cores are substantially faster.

Cache hierarchies also diverge. AMD provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. Intel provides 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The larger per-core L2 cache on the Intel chip likely contributes to its superior single-thread performance.

The integrated graphics differ greatly. The AMD Ryzen AI Max+ 388 includes a Radeon 8060S, while the Intel Core Ultra 5 235T includes Arc Xe-LPG Graphics with 24 execution units. The AMD part is designed with a much more powerful integrated GPU, as indicated by its use of LPDDR5X memory with a quad-channel bus and 256.0 GB/s of memory bandwidth. The Intel chip uses DDR5 memory with a dual-channel bus and 102.4 GB/s of memory bandwidth.

Specification Differences

The base clock speeds differ substantially. The AMD Ryzen AI Max+ 388 runs at 3.60 GHz base, while the Intel Core Ultra 5 235T runs at 2.20 GHz base. Both processors share the same 5.00 GHz boost clock. The higher base clock on the AMD part helps it in burst workloads, while the Intel chip relies on its higher per-core performance to overcome its lower base clock.

Thermal design power also differs. The AMD Ryzen AI Max+ 388 has a 55 watt TDP, while the Intel Core Ultra 5 235T has a 65 watt TDP. This makes the AMD part more power-efficient on paper, though it is a mobile chip while Intel is a desktop chip.

Memory support and bandwidth are major differentiators. The AMD part supports LPDDR5X memory with ECC support, while the Intel chip supports DDR5 without ECC. AMD has a quad-channel memory bus delivering 256.0 GB/s, while Intel has a dual-channel bus delivering 102.4 GB/s. This gives AMD a 2.5x advantage in theoretical memory bandwidth, which is critical for its integrated GPU performance.

PCIe support differs, with AMD providing Gen 4 with 16 lanes, while Intel provides Gen 5 with 20 lanes. The Intel chip offers a more modern and faster PCIe interface. The Intel processor has a die size of 243 mm² and contains 17,800 million transistors, while the AMD processor has a die size of 2x 70.6 mm², with no transistor count listed.

The release dates show the Intel Core Ultra 5 235T launched on January 6, 2025, while the AMD Ryzen AI Max+ 388 launched on January 5, 2026. The Intel part has a launch MSRP of $247, while the AMD part has no listed launch MSRP.
