AMD Ryzen AI Max+ 388 vs Intel Core Ultra 5 245T Comparison

The Verdict

The recorded data splits these two processors into distinct roles. The AMD Ryzen AI Max+ 388 and Intel Core Ultra 5 245T are not direct substitutes; they excel in separate workloads. The Intel part wins 9 of the 15 head-to-head benchmarks, while the AMD part wins 6. However, the magnitude of the AMD wins in specific tasks is substantial. The Intel Core Ultra 5 245T delivers a decisive advantage in single-core and floating-point tasks, while the AMD Ryzen AI Max+ 388 counters with massive leads in data compression, extended instructions, and integer math. The average benchmark score for the AMD part is 49796, placing it in the 90th percentile of all CPUs. The Intel part averages 38194, sitting in the 86th percentile. This suggests the AMD processor, despite losing more individual tests, achieves a higher overall average due to the size of its wins in its strongest areas.

For users whose primary workloads involve heavy data compression, complex encryption, or integer-heavy calculations, the AMD Ryzen AI Max+ 388 is the clear choice based on the data. For workloads that favor high clock speeds, floating-point math, or prime number finding, the Intel Core Ultra 5 245T is superior. The Intel chip also claims the single-core crown, a critical factor for many everyday applications and games that rely on one or two threads. The AMD chip, with its higher average score and 90th percentile ranking, presents a compelling case for mixed workloads that include its specific strengths. The Intel chip, with its 86th percentile, is more of a specialist in single-threaded and FPU-heavy tasks.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Max+ 388 uses the Zen 5 architecture on a 4 nm TSMC process, codenamed Strix Halo. It is a mobile-class part with 8 cores and 16 threads, indicating simultaneous multithreading. Its base clock is 3.60 GHz with a boost clock of 5.00 GHz. The chip is built on a 2x 70.6 mm² die configuration and has a TDP of 55 watts. Its cache hierarchy is 80 KB of L1 per core, 1 MB of L2 per core, and a shared 32 MB of L3 cache. It supports LPDDR5X memory over a quad-channel bus, providing 256.0 GB/s of memory bandwidth. It supports ECC memory and uses PCIe Gen 4 with 16 lanes for the CPU. The integrated graphics are the Radeon 8060S.

The Intel Core Ultra 5 245T belongs to the Core Ultra Series 2, using the Arrow Lake architecture on a 3 nm TSMC process, codenamed Arrow Lake-S. It is a desktop part with 14 cores and 14 threads, meaning it lacks hyper-threading. Its base clock is 2.20 GHz with a boost clock of 5.10 GHz. The chip has 17,800 million transistors on a 243 mm² die. It has a TDP of 65 watts. Its cache is larger per core: 192 KB of L1 per core, 3 MB of L2 per core, but a smaller shared 24 MB of L3 cache. It supports DDR5 memory over a dual-channel bus, providing 102.4 GB/s of memory bandwidth. It also supports ECC memory and uses PCIe Gen 5 with 20 lanes for the CPU. The integrated graphics are the Arc Xe-LPG Graphics 64EU.

The data shows a clear divergence: AMD focuses on memory bandwidth and thread count, while Intel focuses on higher clocks, a larger transistor count, and more physical cores. The Intel chip has more cores (14 vs 8) but the AMD chip has more threads (16 vs 14) due to SMT. The AMD chip's memory bandwidth is more than double that of the Intel chip (256.0 GB/s vs 102.4 GB/s), a factor that likely drives its wins in memory-intensive tasks. Intel's newer 3 nm process node and higher boost clock (5.10 GHz vs 5.00 GHz) contribute to its single-core performance advantage.

Head-to-Head Benchmarks

The benchmark results reveal a clear pattern of specialized strengths. The largest AMD victory comes in PassMark extended instructions, where the Ryzen AI Max+ 388 scores 32719 against the Intel's 22071, a 48.2% advantage. This is followed by a 41.3% win in data compression, with scores of 400887 versus 283812. The AMD chip also wins integer math by 23.6% (109588 vs 88676) and random string sorting by 23.7% (43196 vs 34931). In multithreaded PassMark, the AMD chip leads by 8.6% (33486 vs 30833), and in Cinebench R15 multicore it leads by 8.7% (2872 vs 2641).

The Intel chip's largest win is in Cinebench R23 multicore, where it scores 26208 against the AMD's 18759, a 28.4% margin. This is an interesting result, as the AMD chip wins the older Cinebench R15 multicore test but loses the newer R23 multicore test. The Intel chip also dominates in Cinebench R23 single-core with a 47% lead (3699 vs 1960) and Cinebench R15 single-core with a 19.9% lead (372 vs 298). In PassMark, the Intel chip wins find prime numbers by 55.2% (324 vs 145), floating point math by 33% (108499 vs 72722), data encryption by 15.1% (23656 vs 20092), physics by 19.1% (2278 vs 1843), and single-thread by 4.2% (4367 vs 4185).

The data indicates that AMD's architecture excels at parallel data manipulation tasks, likely aided by its superior memory bandwidth and SMT. Intel's architecture, with its higher boost clock and more cores, dominates in tasks that require raw computational throughput on each core, such as floating-point math and prime number generation. The single-core results are stark: Intel leads by 47% in Cinebench R23 single-core, a massive gap that suggests the Intel chip has a significant IPC and clock speed advantage for lightly threaded workloads.
