AMD Ryzen AI Max PRO 490 vs Intel Core 9 270H Comparison

Where Each One Wins

The data shows two very different mobile processors aimed at different priorities. The AMD Ryzen AI Max PRO 490 uses a 12-core, 24-thread design with a 64 MB L3 cache and quad-channel LPDDR5X memory, while the Intel Core 9 270H uses a 14-core, 20-thread layout with a 24 MB shared L3 cache and dual-channel DDR4/DDR5 support. The benchmark records available for the Intel part show it delivers strong results in both single-thread and multi-thread workloads, but the AMD processor has no recorded benchmark scores in the database, making direct numerical comparison impossible for most tests.

The Intel Core 9 270H clearly wins in every measured category where scores exist. Its Cinebench R23 multi-core score of 18000 and single-core score of 2040 place it in the 86th percentile of all CPUs, a strong position for a mobile chip. The PassMark multithread score of 28764 and single-thread score of 3944 confirm that the Intel part handles both heavily threaded and lightly threaded tasks competently. The AMD Ryzen AI Max PRO 490, by contrast, sits at the 50th percentile with an average benchmark score of 0, meaning the database has no recorded performance data for it.

The use-case split therefore rests on what each processor offers beyond raw compute. The AMD part provides a larger L3 cache (64 MB versus 24 MB), quad-channel memory bandwidth of 273.1 GB/s, and integrated Radeon 8050S graphics. These features point toward memory-bandwidth-sensitive workloads such as large dataset processing, integrated graphics gaming, or AI inference tasks that benefit from high memory throughput. The Intel part, with its higher boost clock of 5.80 GHz, 14 cores, and proven benchmark results, suits general productivity, content creation, and workloads where single-thread responsiveness and established multi-thread performance matter more.

Architecture Differences

The two processors come from different design philosophies. AMD's Ryzen AI Max PRO 490 uses the Gorgon Halo codename with a Zen 5 generation label, built on a 4 nm process at TSMC. The die size is listed as 2x 70.6 mm², indicating a chiplet design. Intel's Core 9 270H uses the Raptor Lake architecture with the Raptor Lake-H codename, part of the Core 9 (Raptor Lake Refresh) generation, on a 10 nm process at Intel's own foundry.

Core and thread counts differ meaningfully. The AMD part offers 12 cores and 24 threads, while the Intel part offers 14 cores and 20 threads. This means the AMD processor relies on simultaneous multithreading across all cores, whereas Intel uses a hybrid layout where only a portion of cores likely support hyper-threading, resulting in fewer threads than cores. The cache hierarchy also diverges: both share 80 KB L1 per core, but AMD uses 1 MB L2 per core versus Intel's 2 MB per core. The L3 cache differs substantially, with AMD providing 64 MB total versus Intel's 24 MB shared.

Memory architecture is a major differentiator. AMD supports only LPDDR5X with a quad-channel bus and a recorded bandwidth of 273.1 GB/s, plus ECC memory support. Intel supports both DDR4 and DDR5 with a dual-channel bus and no ECC support. The database does not list a bandwidth figure for the Intel part, so the AMD memory bandwidth advantage stands as a recorded specification difference.

PCIe capabilities also differ. AMD provides Gen 4 with 16 lanes from the CPU, while Intel provides Gen 5 with 8 lanes from the CPU. This trades raw lane count for newer signaling speed. Integrated graphics differ as well: AMD uses a Radeon 8050S, while Intel uses Iris Xe Graphics with 96 execution units.

Socket and physical packaging are not interchangeable. AMD uses Socket FP11, while Intel uses BGA 1744. Production status for both is active. The AMD part has a release date of 2026-05-19, while the Intel part released 2024-12-17.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors. All available benchmark scores belong to the Intel Core 9 270H. The Intel part's Cinebench R15 multi-core score of 2464 and single-core score of 347 establish a baseline. Its R20 scores are 10268 multi-core and 1449 single-core. R23 scores are 18000 multi-core and 2040 single-core.

PassMark results for the Intel part show a multithread score of 28764 and single-thread score of 3944. Specific workload scores include integer math at 97654, floating point math at 70640, data encryption at 19369, data compression at 333785, extended instructions at 20079, find prime numbers at 112, physics at 1966, and random string sorting at 36867.

The Intel Core 9 270H's nearest rivals in the database are all within a narrow performance band: Intel Core Ultra 9 285H at 38312 (0.1% higher), Intel Xeon w3-2525 at 38392 (0.1% lower), Intel Core i5-13600HX at 38261 (0.2% higher), and AMD Ryzen 7 250 at 38221 (0.3% higher). The average benchmark score for the Intel part is 38335, placing it in the 86th percentile of all CPUs.

Since the AMD Ryzen AI Max PRO 490 has no recorded benchmarks, the database cannot establish any performance wins for it. The wins count is 0 for both processors in the head-to-head dataset.

The Verdict

The recorded data strongly favors the Intel Core 9 270H for anyone who needs verified performance. Its benchmark scores cover the full Cinebench and PassMark suites, and its 86th percentile ranking puts it above the vast majority of CPUs in the database. The 14-core design with a 5.80 GHz boost clock delivers proven single-thread and multi-thread results. The 45-watt TDP also makes it a more power-efficient choice on paper, though actual thermal behavior depends on system design.

The AMD Ryzen AI Max PRO 490 offers specifications that suggest different strengths, but the database has no performance measurements to confirm them. The 64 MB L3 cache, quad-channel LPDDR5X with 273.1 GB/s bandwidth, and ECC support point toward memory-intensive or reliability-focused workloads. The 12-core, 24-thread layout with a 5.00 GHz boost clock and 55-watt TDP indicates a design optimized for throughput rather than peak frequency. Its integrated Radeon 8050S graphics may also provide different capabilities than Intel's Iris Xe Graphics 96EU, but no benchmark data exists to quantify that difference.

For a user who requires immediate, verified compute performance, the Intel Core 9 270H is the only choice supported by measurements. For a user who prioritizes memory bandwidth, ECC support, or a newer manufacturing process, the AMD Ryzen AI Max PRO 490 presents a compelling specification sheet, but the absence of benchmark scores means its real-world behavior remains unverified in the database. The decision ultimately rests on whether measured results or listed specifications carry more weight for the intended workload.
