The AMD Ryzen AI 7 450 and Intel Core 3 100U occupy different tiers in the mobile processor space, and the recorded benchmark data confirms a decisive performance gap. The Ryzen AI 7 450 wins all 15 head-to-head comparisons in the database, with margins ranging from a modest 11.3% in single-threaded work to a massive 183.8% in extended instruction throughput. This analysis breaks down those results, the architectural foundations, and where each processor fits based on measured outcomes.

Head-to-Head Benchmarks

The largest single victory for the AMD Ryzen AI 7 450 comes in the PassMark extended instructions test, where it scores 22400 against Intel’s 7894, a delta of 183.8%. This category measures SIMD and specialized instruction performance, indicating a substantial advantage in workloads that leverage advanced CPU extensions. The Ryzen part also dominates multi-threaded rendering: in Cinebench R23 multicore, it posts 18316 versus 10624, a 72.4% lead. The Cinebench R15 multicore result is even more lopsided, with AMD scoring 2713 against Intel’s 1070, a 153.6% difference.

Integer and floating-point math tell a similar story. PassMark integer math shows AMD at 88531 versus Intel’s 39580, a 123.7% advantage. Floating-point math follows with 54447 against 28322, a 92.2% lead. Data compression and encryption also favor AMD heavily: compression scores are 315906 versus 136497 (131.4% higher), while encryption posts 16247 against 8128, a 99.9% gap. Random string sorting, another memory-latency-sensitive test, shows AMD at 35648 versus 15191, a 134.7% delta.

The narrowest margins are in single-threaded tests, where the Ryzen AI 7 450 still wins but less decisively. PassMark single-thread score is 3901 versus 3506, an 11.3% lead. Cinebench R23 single-core shows 2038 against 1499, a 36% advantage, and Cinebench R15 single-core is 215 versus 150, a 43.3% delta. PassMark physics, a test of rigid body simulation, sees AMD at 1578 against Intel’s 876, an 80.1% margin. Find prime numbers, a pure integer loop, shows 89 versus 52, a 71.2% lead. Across all 15 recorded benchmarks, the Ryzen AI 7 450 wins every category, with no Intel counters.

Architecture Differences

The two processors come from fundamentally different design eras. The AMD Ryzen AI 7 450 uses the Zen 5 architecture on a 4 nm TSMC process, with the codename Gorgon Point and a generation label of Ryzen AI 400 (Zen 5 / Zen 5c). It packs 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel Core 3 100U uses Raptor Lake architecture on Intel’s 10 nm process, with the codename Raptor Lake-U. It offers 6 cores and 8 threads, a base clock of 1.20 GHz, and a boost clock of 4.70 GHz.

Cache configurations differ in structure. Both allocate 80 KB of L1 per core and 1 MB of L2 per core on the AMD side, while Intel uses 1.25 MB of L2 per core. The L3 cache is 8 MB on AMD, shared, versus 10 MB shared on Intel. Memory support diverges: AMD accepts DDR5 and LPDDR5X with dual-channel access and a measured memory bandwidth of 89.6 GB/s, while Intel supports DDR4 and DDR5 dual-channel but has no recorded bandwidth figure. ECC memory is supported on AMD but not on Intel.

The integrated graphics also differ: AMD uses the Radeon 860M, while Intel ships UHD Graphics 64EU. PCIe lanes are a notable gap: AMD provides Gen 4 with 16 lanes (CPU only), Intel provides Gen 4 with 8 lanes (CPU only). The sockets reflect different platform strategies: AMD uses AMD Socket FP8, Intel uses Intel BGA 1744. Process node and foundry are distinct: TSMC 4 nm for AMD, Intel 10 nm for Intel. Die size is recorded for AMD at 195 mm², but no die size is listed for Intel.

The thermal design power differs significantly: AMD is rated at 28 W, Intel at 15 W. This explains part of the performance gap, as the AMD part has more power headroom. However, the architectural efficiency of Zen 5 on a smaller node also contributes to the single-threaded wins despite the higher power envelope. The Intel part’s boost clock of 4.70 GHz trails AMD’s 5.10 GHz, and its lower core count reduces multi-threaded throughput. The database also shows the release timeline: Intel launched on 2024-01-07, while AMD is dated 2026-01-04, indicating a later-generation product.

Where Each One Wins

The AMD Ryzen AI 7 450 wins every measured benchmark category in the database. Its strongest showings are in multi-threaded rendering (Cinebench R23 multicore, 72.4% ahead), integer math (123.7% ahead), and extended instructions (183.8% ahead). These results indicate dominance in content creation, scientific computing, and any workload that scales across cores or uses advanced SIMD. The 16 threads and 89.6 GB/s memory bandwidth support heavy parallel tasks. The integrated Radeon 860M and 16 PCIe lanes also give it more headroom for graphics and expansion.

The Intel Core 3 100U shows no benchmark wins, but its lower 15 W TDP and support for DDR4 memory make it a fit for power-constrained designs where platform cost and memory compatibility matter more than raw throughput. Its 10 MB L3 cache is larger than AMD’s 8 MB, which can help in cache-sensitive single-threaded scenarios, though the recorded single-thread scores still favor AMD. Intel’s 6 cores and 8 threads, paired with a 4.70 GHz boost clock, position it as a mainstream mobile part for everyday productivity, web browsing, and light multitasking. Its lack of ECC support and fewer PCIe lanes limit workstation or high-end expansion use cases.

The database positions the AMD part in the 87th percentile of all CPUs, while Intel sits in the 70th percentile. The average benchmark score for AMD is 39485, against Intel’s 16148. AMD’s nearest rivals include the Ryzen 7 PRO 8840HS (delta -0.3%) and Ryzen 7 9800X3D (delta -0.7%), indicating it trades blows with desktop-class chips. Intel’s nearest rivals are older parts like the Core i7-10850H (delta -0.3%) and Ryzen 5 4600H (delta -1.2%), showing it aligns with previous-generation mid-range hardware. For any workload measured in this database, the AMD Ryzen AI 7 450 is the clear performer, while Intel offers a lower-power alternative with a dated architecture.
