Architecture Differences

The AMD Ryzen AI 7 450 is built on Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI 400 generation (Zen 5 / Zen 5c). It uses a 4 nm process from TSMC with a die size of 195 mm². The Intel Core 9 270H, by contrast, is based on Raptor Lake architecture under the Raptor Lake-H codename, part of the Core 9 (Raptor Lake Refresh) generation. Intel fabricates this chip on a 10 nm process at its own foundry.

Core and thread counts diverge significantly. AMD offers 8 cores and 16 threads, while Intel offers 14 cores and 20 threads. This core advantage for Intel does not translate into universal performance leadership, as the benchmark data shows a more nuanced picture. Clock speeds also differ: AMD's base clock is 2.00 GHz with a boost of 5.10 GHz, while Intel runs a 2.70 GHz base and 5.80 GHz boost.

Cache hierarchies show structural differences. Both share the same 80 KB per core L1 cache. The L2 cache differs: AMD provides 1 MB per core, Intel provides 2 MB per core. L3 cache is more divergent, with AMD offering 8 MB total versus Intel's 24 MB shared. The larger Intel cache pool likely contributes to its wins in data-heavy workloads.

Memory support is another area of divergence. AMD supports DDR5 and LPDDR5X with a dual-channel bus and 89.6 GB/s of bandwidth. Intel supports DDR4 and DDR5 on a dual-channel bus, though its memory bandwidth figure is not recorded in the database. AMD also supports ECC memory, which Intel does not. PCIe capabilities differ as well: AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 8 lanes (CPU only).

Integrated graphics differ by vendor. AMD pairs the chip with Radeon 860M graphics, while Intel uses Iris Xe Graphics with 96 execution units. Both target the mobile market segment and are currently in active production. The AMD part was released on 2026-01-04, while the Intel part was released on 2024-12-17.

Where Each One Wins

The AMD Ryzen AI 7 450 claims victory in Cinebench R15 multi-core with a 10.1% margin, Cinebench R23 multi-core with a 1.8% margin, and PassMark extended instructions with an 11.6% margin. These wins point toward strengths in multi-threaded rendering workloads and specialized instruction execution. The extended instructions result is particularly interesting, as it suggests AMD's Zen 5 architecture handles certain SIMD or specialized instruction sets more efficiently than Intel's Raptor Lake design.

The Intel Core 9 270H dominates across the remaining 12 benchmarks. Its largest wins come in floating point math, where it leads by 22.9%, and prime number finding, where it leads by 20.5%. Physics performance also favors Intel substantially at 19.7% ahead. Data encryption shows a 16.1% Intel advantage, and integer math shows a 9.3% lead. The Intel chip also wins in data compression by 5.4%, multi-thread performance by 8.4%, and random string sorting by 3.3%.

Single-thread performance splits oddly between the two. In Cinebench R23 single-core, the difference is essentially negligible at 0.1% in Intel's favor. But in Cinebench R15 single-core, Intel leads by a massive 38%. This inconsistency suggests the benchmark versions stress different aspects of the architecture. PassMark single-thread tests show a modest 1.1% Intel edge.

For users prioritizing multi-core rendering, AMD is the stronger choice. For nearly everything else in the recorded data, Intel holds the advantage. The PassMark multithread score of 28764 for Intel versus 26350 for AMD reinforces that Intel's overall multi-thread throughput is higher, even though AMD wins the specific Cinebench multi-core tests.

Head-to-Head Benchmarks

The Cinebench suite offers the clearest illustration of the split between these two processors. In Cinebench R15 multi-core, AMD wins decisively with 2713 points against 2464, a 10.1% advantage. This is AMD's largest victory in any benchmark. In Cinebench R23 multi-core, AMD wins again but by a much slimmer margin: 18316 versus 18000, just 1.8%. The single-core tests tell a different story. Cinebench R15 single-core shows Intel at 347 against AMD's 215, a 38% gap that is the largest margin in either direction across all recorded tests. Cinebench R23 single-core is nearly a tie, with Intel at 2040 and AMD at 2038, a 0.1% difference.

The PassMark suite heavily favors Intel. Floating point math shows Intel at 70640 versus AMD's 54447, a 22.9% lead. Prime number finding: Intel 112, AMD 89, a 20.5% lead. Physics: Intel 1966, AMD 1578, a 19.7% lead. Data encryption: Intel 19369, AMD 16247, a 16.1% lead. Integer math: Intel 97654, AMD 88531, a 9.3% lead. Multithread: Intel 28764, AMD 26350, an 8.4% lead. Data compression: Intel 333785, AMD 315906, a 5.4% lead. Random string sorting: Intel 36867, AMD 35648, a 3.3% lead. Single-thread: Intel 3944, AMD 3901, a 1.1% lead.

AMD's only PassMark win comes in extended instructions, where it scores 22400 against Intel's 20079, an 11.6% advantage. This result, combined with the Cinebench multi-core wins, suggests AMD's architecture has specific strengths that do not generalize across the full benchmark suite.

The average benchmark scores provide context for the head-to-head results. AMD's average of 39485 exceeds Intel's 38335, yet Intel wins 12 of 15 direct comparisons. This apparent contradiction resolves when considering the benchmark mix: AMD's wins include the heavily weighted Cinebench multi-core tests and extended instructions, while Intel's wins span a broader range of PassMark workloads. The percentile rankings reflect the overall closeness, with AMD at 87 and Intel at 86.

The Verdict

The data presents a clear but nuanced picture. The Intel Core 9 270H wins the majority of head-to-head tests, claiming 12 of 15 benchmarks. Its strengths lie in math-heavy workloads, physics, encryption, compression, and general multi-thread throughput. The 22.9% lead in floating point math and the 20.5% lead in prime number finding are substantial margins that would matter for scientific computing and number-crunching tasks. The 19.7% physics advantage could influence simulation and game physics performance. The 16.1% encryption lead benefits security-related workloads.

The AMD Ryzen AI 7 450 wins fewer tests but wins them meaningfully. The 10.1% Cinebench R15 multi-core margin is the second-largest victory recorded in this comparison. The 11.6% extended instructions win suggests AMD's Zen 5 architecture handles specialized instruction sets particularly well. The Cinebench R23 multi-core win, while narrow at 1.8%, indicates AMD can hold its own in modern rendering workloads despite having fewer cores and threads.

The average benchmark score favors AMD at 39485 versus 38335, and AMD's 87th percentile ranking edges out Intel's 86th. AMD also offers ECC memory support, a lower TDP of 28 watts versus 45 watts, and a smaller 4 nm process node. Intel counters with a higher boost clock of 5.80 GHz, a larger 24 MB L3 cache, PCIe Gen 5 support, and a launch MSRP of $697.

For rendering-focused users who prioritize Cinebench-style multi-core performance, the AMD Ryzen AI 7 450 is the data-supported choice. For users whose workloads span math, encryption, compression, and general multithreaded applications, the Intel Core 9 270H wins more frequently and by larger margins in most categories. The single-thread results are mixed: Intel dominates Cinebench R15 single-core by 38%, but the two are nearly identical in Cinebench R23 single-core and close in PassMark single-thread. The Intel Core 9 270H is the broader performer in the recorded data, while the AMD Ryzen AI 7 450 excels in targeted scenarios.
