AMD Ryzen AI Max+ 388 vs Intel Core Ultra 7 265T Comparison

The AMD Ryzen AI Max+ 388 and Intel Core Ultra 7 265T are two very different processors that land in the same performance percentile. The database records an average benchmark score of 49796 for the AMD part and 47697 for the Intel part, placing both in the 90th percentile of all CPUs. Yet the head-to-head results tell a more nuanced story: Intel wins 12 of the 15 shared tests, while AMD wins 3. This split suggests that the average score masks significant workload-specific differences.

Head-to-Head Benchmarks

The Intel Core Ultra 7 265T dominates the Cinebench suite. In Cinebench R23 multicore, it scores 31558 against AMD's 18759, a 40.6% advantage. The single-core gap is even wider: 4455 versus 1960, a 56% lead. Cinebench R15 shows the same pattern, with Intel ahead 3180 to 2872 in multicore (9.7%) and 449 to 298 in single-core (33.6%). These are not marginal wins; they indicate a substantial performance difference in rendering and single-threaded workloads.

Intel also wins several PassMark tests. Floating point math goes to Intel by 44% (129817 vs 72722), and find prime numbers by 55% (322 vs 145). Data encryption favors Intel by 32.3% (29687 vs 20092), physics by 22.9% (2391 vs 1843), and multithread by 9.7% (37084 vs 33486). Even random string sorting, a test that often rewards memory bandwidth, goes to Intel by 2.7% (44400 vs 43196). Single-thread performance is close but still Intel's: 4338 vs 4185, a 3.5% edge.

AMD's three wins are concentrated in specific instruction-heavy areas. Data compression shows AMD ahead by 8.3% (400887 vs 370158). Extended instructions, which likely reflect SIMD or specialized operations, favor AMD by 14.4% (32719 vs 28609). Integer math is a narrow AMD win at 4.4% (109588 vs 104943). These results suggest that while Intel is broadly faster, AMD has a niche in certain computational patterns.

Architecture Differences

The two processors are built on different nodes and designs. AMD uses a 4 nm process from TSMC, while Intel uses a 3 nm process, also from TSMC. AMD's architecture is Zen 5 under the codename Strix Halo, while Intel uses Arrow Lake. The core counts diverge sharply: AMD has 8 cores and 16 threads, Intel has 20 cores and 20 threads, meaning Intel does not use simultaneous multithreading. Base clocks are 3.60 GHz for AMD and 1.50 GHz for Intel, but boost clocks are 5.00 GHz and 5.30 GHz respectively. TDP also differs: AMD is rated at 55W, Intel at 35W.

Cache hierarchies are distinct. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. Intel offers 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Memory support is a major differentiator: AMD uses LPDDR5X over a quad-channel bus with 256.0 GB/s bandwidth, while Intel uses DDR5 over a dual-channel bus with 102.4 GB/s. AMD also lists ECC memory support as true, while Intel lists it as false. PCIe connectivity favors Intel: Gen 5 with 20 lanes versus AMD's Gen 4 with 16 lanes. Integrated graphics differ as well: AMD has a Radeon 8060S, Intel has an Arc Xe-LPG Graphics 64EU. Die size is reported as 2x 70.6 mm² for AMD and 243 mm² for Intel; Intel also lists 17,800 million transistors, while AMD does not provide that figure. Release dates are close: AMD on 2026-01-05, Intel on 2025-01-06. AMD is classified as a mobile part, Intel as a desktop part.

Where Each One Wins

The Intel Core Ultra 7 265T is the clear winner in rendering and general compute. It takes every Cinebench test, including a 40.6% lead in R23 multicore and a 56% lead in R23 single-core. It also wins PassMark multithread, physics, floating point math, data encryption, find prime numbers, random string sorting, and single-thread tests. For users running CPU-bound workloads like video encoding, 3D rendering, or scientific simulations that rely on floating point, the data points squarely to Intel.

The AMD Ryzen AI Max+ 388 wins in data compression, extended instructions, and integer math. These are not trivial areas: data compression is common in file archiving and database workloads, and extended instructions often matter for cryptography or specialized math. AMD also holds a higher average benchmark score (49796 vs 47697), meaning that across the full set of recorded tests, it comes out slightly ahead on average. Additionally, AMD offers quad-channel LPDDR5X memory with 256.0 GB/s bandwidth and ECC support, which are not benchmark scores but are relevant for memory-intensive or reliability-sensitive tasks.

The Verdict

Based on the recorded data, the Intel Core Ultra 7 265T is the stronger performer in the majority of shared benchmarks, winning 12 of 15 tests including all Cinebench versions. Its 56% lead in Cinebench R23 single-core and 40.6% lead in multi-core make it the obvious choice for CPU-bound rendering and single-threaded applications. The AMD Ryzen AI Max+ 388, however, wins in data compression, extended instructions, and integer math, and holds a higher average benchmark score (49796 vs 47697). For users whose workloads rely on those specific operations, or who need ECC memory support and quad-channel LPDDR5X bandwidth, the AMD part offers distinct advantages. The Intel part also has a lower TDP (35W vs 55W) and a higher boost clock (5.30 vs 5.00 GHz). Ultimately, the choice depends on the workload: Intel for general compute and rendering, AMD for specialized instruction-heavy tasks and memory bandwidth.
