AMD Ryzen AI 9 HX 370 vs Intel Core 3 100U Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the AMD Ryzen AI 9 HX 370 across all 15 head-to-head benchmark comparisons. The Intel Core 3 100U does not register a single win, and the margin of victory varies dramatically depending on the workload.

The largest single advantage appears in PassMark extended instructions, where the AMD part scores 31,653 against Intel's 7,894, a 301% delta. This indicates a massive gap in workloads that leverage advanced CPU instruction sets, likely including encryption, SIMD-heavy code, and certain scientific computing tasks.

PassMark data compression shows a similar trend. The Ryzen AI 9 HX 370 scores 445,719 versus 136,497 for the Core 3 100U, a 226.5% advantage. This is particularly relevant for file archiving, database operations, and any application that moves significant amounts of data through compression algorithms.

Cinebench R15 multicore results reinforce the pattern. AMD delivers 3,409.5 points against Intel's 1,070, a 218.6% lead. The R15 single-core test narrows the gap but still favors AMD by 104.3%, with scores of 306.5 and 150 respectively. This suggests the AMD architecture holds a substantial per-thread efficiency advantage, not just a core-count advantage.

PassMark integer math shows a 210.6% delta, with AMD at 122,933 and Intel at 39,580. Random string sorting follows at 220.7%, AMD scoring 48,723 versus 15,191. These results indicate the AMD processor handles general-purpose integer work and memory-heavy sorting tasks with significantly more throughput.

The multithreaded PassMark score shows AMD at 35,148 against Intel's 12,522, a 180.7% delta. Floating point math shows a 171.5% advantage, AMD at 76,892, Intel at 28,322. Data encryption, a workload that stresses both CPU arithmetic and memory bandwidth, shows AMD ahead by 173.8%, scoring 22,252 versus 8,128.

The smallest margin in the entire comparison is PassMark single-thread performance. AMD scores 3,973, Intel scores 3,506, a 13.3% delta. This is the only benchmark where the Intel part comes within a reasonable distance. It suggests that for lightly threaded, latency-sensitive tasks, the Core 3 100U is not completely outclassed, though it still loses.

Cinebench R23 results show a 104.8% multicore delta, AMD at 21,761, Intel at 10,624. The R23 single-core test shows a 34.6% lead for AMD, with scores of 2,018 versus 1,499. PassMark physics shows a 114.7% delta, AMD at 1,881, Intel at 876. Prime number finding, which stresses branch prediction and integer division, shows a 142.3% delta, AMD at 126, Intel at 52.

These numbers paint a clear picture. The AMD Ryzen AI 9 HX 370 dominates in every measured category, but the degree of dominance varies from a modest 13.3% in single-thread work to over 300% in extended instruction workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses a hybrid Zen 5 configuration in its Strix Point package, built on a 4 nm TSMC process. The chip contains 12 cores and 24 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. Intel's Core 3 100U uses Raptor Lake-U architecture on a 10 nm Intel process, with 6 cores and 8 threads, base clock of 1.20 GHz and boost of 4.70 GHz.

The core count difference is straightforward: AMD provides double the physical cores and triple the thread count. This directly explains the massive multicore deltas seen in Cinebench and PassMark multithread tests.

Cache configurations differ in structure. Both use 80 KB of L1 per core, but AMD allocates 1 MB of L2 per core while Intel uses 1.25 MB per core. The L3 cache is the significant divider: AMD provides 16 MB, Intel provides 10 MB shared. For workloads with high cache reuse, the larger AMD L3 likely contributes to its compression and sorting advantages.

Process node differences are stark. AMD's 4 nm TSMC process versus Intel's 10 nm process represents two full generations of lithography advancement. This explains the efficiency gap in the benchmark data, where AMD achieves far higher performance while the base TDP figures show AMD at 28 W versus Intel at 15 W. The AMD part uses more power but delivers far more work per watt in multithreaded scenarios.

Memory support differs as well. AMD supports DDR5 and LPDDR5X with dual-channel configuration and a rated bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5, also dual-channel, but the database records no bandwidth figure for it. This memory bandwidth advantage for AMD likely plays a role in the data compression and encryption results.

PCIe connectivity shows AMD with Gen 4, 16 lanes, while Intel provides Gen 4, 8 lanes. This affects expansion options for NVMe drives and discrete GPUs.

Integrated graphics differ completely. AMD ships the Radeon 890M, Intel ships UHD Graphics 64EU. The database does not include graphics benchmarks, but the hardware names indicate a significant capability gap for gaming or GPU-accelerated compute.

Release timing favors AMD by several months. Intel's Core 3 100U released in January 2024, AMD's Ryzen AI 9 HX 370 in June 2024. Both are listed as Active in production.

Where Each One Wins

The AMD Ryzen AI 9 HX 370 wins in every single benchmark category where both chips have recorded data. Its largest wins are in extended instructions (301% delta), data compression (226.5%), random string sorting (220.7%), and integer math (210.6%). These are workloads involving encryption, compression, sorting algorithms, and general arithmetic. Its smallest win is single-thread PassMark at 13.3%, which still favors AMD.

The Intel Core 3 100U has no benchmark wins in the recorded data. Its relative strengths are limited to the single-thread category where the delta narrows to 13.3%, and its lower TDP of 15 W makes it a candidate for fanless or ultra-low-power designs. The database shows no scenario where the Intel part outperforms AMD.

For creators running Cinebench renders, the AMD part delivers roughly double the multicore score. For developers compiling code or analysts processing large datasets, the compression and integer math results indicate substantially shorter completion times. For users who need PCIe Gen 4 with 16 lanes for multiple high-speed NVMe drives or a discrete GPU, AMD provides more headroom.

The Intel Core 3 100U remains a functional mobile processor for basic productivity, as its 70th percentile ranking shows. It is not a poor chip in absolute terms. It simply faces a competitor that outperforms it by a wide margin in every measured metric. The choice is clear: the AMD Ryzen AI 9 HX 370 delivers higher performance across the board, with the only trade-off being a higher TDP and a requirement for the AMD Socket FP8 platform.
