AMD Ryzen AI 9 HX 375 vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear hierarchy between these two mobile processors. Out of 15 recorded head-to-head comparisons, the AMD Ryzen AI 9 HX 375 claims 13 wins, while the Intel Core 3 305 takes only 2. The magnitude of those wins, however, tells a more nuanced story.

The most dramatic separation appears in integer math. The AMD part scores 121754 against Intel's 32295, a delta of 277%. This is the largest single gap in the entire dataset. Data compression shows a similar trend, with AMD at 404918 versus 146857, a 175.7% advantage. Random string sorting follows at 152.8% (44552 vs 17623). These three workloads all favor heavy multithreading and wide execution resources, which aligns with the core count disparity.

Cinebench results reinforce the multi-core dominance. In Cinebench R15 multi-core, AMD scores 3334 against Intel's 1322, a 152.2% lead. The R23 multi-core test shows a narrower but still substantial 66.2% gap (21812 vs 13123). Extended instructions also favor AMD heavily, with a 116.1% delta (29269 vs 13543). The passmark multithread score shows 113.2% (32916 vs 15439), and data encryption shows 88.8% (20802 vs 11019).

Floating point math delivers a 77.7% advantage (75153 vs 42284). Physics simulation shows 47.5% (1819 vs 1233). Even the smallest multi-core win, find prime numbers, shows 6.1% (122 vs 115). The single-core Cinebench R23 result is close, with AMD ahead by only 7.3% (1988 vs 1852). Cinebench R15 single-core shows a 61.8% gap (301 vs 186), but this is an older test with lower absolute scores, making percentage swings larger.

The Intel part's only wins come in the PassMark single-thread tests. Both passmark_single_thread and passmark_singlethread record the same scores: Intel at 3977, AMD at 3867. The delta is -2.8%, meaning Intel holds a modest 110-point edge. This is the only area where the Intel architecture outperforms, and the margin is small enough to suggest similar single-thread capability in most real-world tasks.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses a 12-core, 24-thread configuration based on the Zen 5 architecture, codenamed Strix Point. This is a hybrid arrangement from the Ryzen AI 300 generation, combining Zen 5 and Zen 5c cores. Intel counters with a 6-core, 6-thread design codenamed Wildcat Lake, from the Core 3 generation. Notably, Intel's part has no simultaneous multithreading, which explains its low thread count relative to cores.

The process nodes differ. AMD uses a 4 nm process from TSMC, with a die size of 233 mm². Intel uses a 3 nm process from its own foundry. The die size for Intel is not recorded in the database. The cache structures also diverge significantly. AMD allocates 80 KB of L1 per core and 1 MB of L2 per core, with 16 MB of shared L3. Intel provides 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3.

Clock speeds show a tradeoff. AMD has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. Intel runs at 1.50 GHz base and 4.30 GHz boost, but still manages to win the PassMark single-thread test. The power envelope is also distinct: AMD is rated at 28 W TDP, while Intel sits at 15 W TDP. The database records no power draw measurements beyond TDP, so direct efficiency comparisons are not possible.

Memory support is another divergence. Both support DDR5 and LPDDR5X, but AMD uses a dual-channel memory bus with 89.6 GB/s bandwidth. Intel uses a single-channel bus with 59.7 GB/s. This bandwidth difference likely contributes to AMD's advantage in data-heavy workloads like compression and encryption. PCIe lanes also differ: AMD offers Gen 4 with 16 lanes (CPU only), while Intel offers Gen 4 with 6 lanes (CPU only).

Integrated graphics differ as well. AMD pairs with the Radeon 890M. Intel includes Intel Xe3 Graphics with one Xe core. No graphics benchmarks are present in the data, so the comparison cannot go beyond specifications. Both processors are locked multipliers, and neither supports ECC memory. AMD uses Socket FP8, while Intel uses BGA 1516. The release dates are far apart: AMD launched on 2024-06-30, Intel on 2026-04-15.

The Verdict

The data indicates the AMD Ryzen AI 9 HX 375 is the stronger processor for almost every recorded workload. Its average benchmark score of 46030 places it in the 89th percentile of all CPUs in the database. Intel averages 18302, in the 72nd percentile. AMD's nearest rivals include the Intel Core Ultra 5 235 (delta -0.1%), the AMD EPYC 4364P (delta 0.1%), and the Intel Core i9-13900HX (delta -0.1%). These are all desktop or high-end mobile parts, which suggests AMD's mobile chip competes at a much higher tier than its 28 W TDP would imply.

Intel's Core 3 305 sits among lower-tier rivals: the Intel Core i3-14100 (delta -0.1%), Intel Core 5 330 (delta -0.2%), Intel Core 7 360 (delta -0.4%), and AMD Ryzen 5 2600E (delta 0.4%). The average scores of these rivals are within 0.4% of Intel's, meaning the Core 3 305 is firmly in entry-level territory.

For users prioritizing multi-core throughput, heavy data processing, or sustained parallel workloads, the AMD part is the clear choice. The 152.2% lead in Cinebench R15 multi-core and the 277% lead in integer math are not marginal differences. For users who care about single-thread performance in short bursts, the Intel part holds a slight edge, but it is only 2.8% and confined to one benchmark family.

The Intel part's launch MSRP is $309, while AMD has no recorded launch MSRP. No pricing comparisons beyond that single figure are permitted by the data.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 wins in every multi-threaded category recorded. The data shows its strongest relative performance in integer math (277% lead), data compression (175.7%), random string sorting (152.8%), Cinebench R15 multi-core (152.2%), and extended instructions (116.1%). It also leads in multithread score (113.2%), data encryption (88.8%), floating point math (77.7%), Cinebench R23 multi-core (66.2%), physics (47.5%), and both Cinebench single-core tests (61.8% and 7.3%). The find prime numbers test is close, with AMD ahead by only 6.1%.

The Intel Core 3 305 wins in the PassMark single-thread tests, with a 2.8% edge over AMD. This is the only recorded benchmark category where Intel outperforms. The margin is small, and the Cinebench single-core tests go the other way, so this win may not translate into a perceptible advantage in daily use.

The use-case split is straightforward. For rendering, data processing, encryption, compression, or any parallel workload, the AMD part is dramatically faster. For applications that rely on a single thread and run for short durations, the Intel part offers a marginal edge. The Intel part also carries a lower TDP (15 W vs 28 W), which could matter in thermally constrained chassis, but the database records no efficiency measurements beyond TDP to confirm real-world power draw. The AMD part's 89th percentile ranking versus Intel's 72nd percentile further confirms its higher overall standing in the database.
