AMD Ryzen AI 9 HX PRO 470 vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall victory for the AMD Ryzen AI 9 HX PRO 470, which wins 9 of the 15 head-to-head benchmark comparisons, while the Intel Arc G3 EXTREME wins the remaining 6. The dominant margin for AMD appears in integer math, where the Ryzen AI 9 HX PRO 470 scores 127573 against the Arc G3 EXTREME's 71164, a 79.3% advantage. This is the single largest delta in the entire comparison and reflects a substantial difference in general-purpose arithmetic throughput.

Cinebench results heavily favor the AMD part. In Cinebench R15 multi-core, the AMD chip scores 3234 versus 2192 for Intel, a 47.5% lead. The R23 multi-core test shows a 30.3% advantage for AMD (19095 vs 14655). Single-core Cinebench results are closer but still favor AMD: R15 single-core shows a 17.2% lead (313 vs 267) and R23 single-core shows a 10.3% lead (2054 vs 1862). These numbers indicate that the AMD processor delivers superior performance in both lightly threaded and heavily threaded render workloads.

Data compression also strongly favors AMD. The PassMark data compression score for the Ryzen AI 9 HX PRO 470 is 461195, compared to 307094 for the Arc G3 EXTREME, a 50.2% difference. Extended instruction performance follows a similar pattern, with AMD scoring 32803 versus 24017, a 36.6% lead. Random string sorting shows AMD ahead by 30.8% (48824 vs 37331). Multithreaded performance in PassMark shows AMD at 36402 versus Intel's 30659, an 18.7% advantage.

The Intel Arc G3 EXTREME, however, posts wins in several specific workloads. The most notable Intel victory is in prime number finding, where it scores 248 versus AMD's 136, a 45.2% advantage. This suggests the Intel architecture handles that particular algorithmic pattern much more efficiently. Floating-point math also goes to Intel, with a score of 86929 versus AMD's 80023, a 7.9% lead. Physics simulation in PassMark shows Intel ahead by 23.9% (2515 vs 1915). Data encryption is a narrow Intel win at 23881 versus 22929, a 4% margin. Single-thread performance in PassMark slightly favors Intel at 4293 versus 4050, a 5.7% edge.

The average benchmark score for the AMD processor is 56306, placing it in the 92nd percentile of all CPUs in the database. The Intel processor's average is 36699, in the 85th percentile. The AMD part's nearest rivals include the AMD Ryzen AI Max 390 (average 56273, just 0.1% lower), the AMD Ryzen Threadripper PRO 3955WX (56555, 0.4% higher), the Intel Core i9-14900HX (56004, 0.5% lower), and the Intel Core 7 253PQE (55919, 0.7% lower). The Intel Arc G3 EXTREME sits near the AMD Ryzen 5 5600F (36945, 0.7% higher), the AMD Ryzen 5 5500X3D (37018, 0.9% higher), and the AMD Ryzen AI 7 PRO 450 (37093, 1.1% higher). These proximity values confirm that the AMD chip competes with high-end desktop and mobile processors, while the Intel chip aligns with mid-range desktop parts.

Architecture Differences

The two processors diverge sharply at the architectural level. The AMD Ryzen AI 9 HX PRO 470 uses a Zen 5 core architecture, fabricated on a 4 nm TSMC process, with a die size of 233 mm². The Intel Arc G3 EXTREME is built on a 3 nm Intel process using a Panther Lake codename and an Arc G3 generation label; its architecture field is not recorded, and its die size is not recorded.

Core configuration differs significantly. AMD provides 12 cores and 24 threads, indicating simultaneous multithreading. Intel provides 14 cores and 14 threads, with no multithreading, so the AMD chip offers more logical threads despite having fewer physical cores. The AMD base clock is 2.00 GHz with a boost of 5.20 GHz. The Intel chip has a base clock of 1.90 GHz and a boost of 4.70 GHz. Although the Intel part has more physical cores, the AMD chip has higher clock speeds on both ends.

Cache hierarchy differs in size and sharing. AMD uses an 80 KB L1 per core, 1 MB L2 per core, and 16 MB of L3 cache. Intel uses a 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB of shared L3 cache. Intel's larger per-core L1 and L2 caches may contribute to its wins in prime number finding and physics, while AMD's larger L3 aggregate and multithreading likely help in compression and integer workloads.

Memory support also differentiates the two. AMD supports both DDR5 and LPDDR5X memory over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s and ECC memory support. Intel supports only LPDDR5X, also dual-channel, but with a higher recorded bandwidth of 136.5 GB/s and no ECC support. The Intel part's higher memory bandwidth may explain its edge in floating-point math and encryption, where data movement is intensive.

PCIe connectivity differs. AMD provides PCIe Gen 4 with 16 lanes (CPU only). Intel provides PCIe Gen 5 with 4 lanes (CPU only). The AMD part has more lanes but an older generation; the Intel part has fewer lanes but a newer standard. Integrated graphics also differ: AMD uses the Radeon 890M, while Intel uses the Arc B390. Both processors are mobile parts, are actively in production, and have locked multipliers. The AMD part uses an AMD Socket FP8, while the Intel part uses Intel BGA 2540. The AMD part number is 100-000001937, and the Intel part number is SA4R3.

The Verdict

The data supports a clear performance hierarchy. The AMD Ryzen AI 9 HX PRO 470 delivers a substantially higher average benchmark score (56306 vs 36699) and sits in the 92nd percentile of all CPUs, while the Intel Arc G3 EXTREME sits in the 85th percentile. The AMD chip wins the majority of head-to-head tests, including the most demanding multi-core rendering workloads: Cinebench R15 multi-core shows a 47.5% lead, and Cinebench R23 multi-core shows a 30.3% lead. Integer math is the standout, with AMD ahead by 79.3%. Any workload that relies on compression, extended instructions, or random string sorting will favor the AMD processor by large margins.

The Intel Arc G3 EXTREME is the better choice for a narrower set of tasks. Its 45.2% lead in prime number finding, 23.9% lead in physics simulation, and 7.9% lead in floating-point math make it the stronger part for those specific algorithmic patterns. It also has a modest 5.7% edge in PassMark single-thread performance and a 4% edge in data encryption. The Intel part's higher memory bandwidth (136.5 GB/s vs 89.6 GB/s) and larger per-core caches (192 KB L1, 2.5 MB L2) likely underpin these wins.

From a platform perspective, the AMD chip offers ECC memory support, PCIe Gen 4 with 16 lanes, and both DDR5 and LPDDR5X memory support. The Intel chip offers PCIe Gen 5 with 4 lanes, LPDDR5X-only support, and no ECC. The AMD part also has a lower TDP of 28 W compared to Intel's 25 W, a difference of 3 W that is minor in practice.

For users prioritizing multi-threaded productivity, content creation, and integer-heavy computation, the AMD Ryzen AI 9 HX PRO 470 is decisively ahead. For users focused on physics simulation, prime number workloads, or floating-point math with a preference for slightly higher single-thread PassMark scores, the Intel Arc G3 EXTREME has specific advantages, though its overall average score is 34.8% lower than AMD's. The record is unambiguous: AMD wins 9 of 15 direct comparisons, and its wins are generally larger in magnitude than Intel's wins.
