AMD Ryzen AI 9 HX PRO 370 vs Intel Arc G3 EXTREME Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen AI 9 HX PRO 370 and the Intel Arc G3 EXTREME is not a clean generational victory; it is a functional one. The AMD part wins 9 of the 15 head-to-head comparisons, while the Intel part takes 6. The pattern is unmistakable: AMD dominates in heavily threaded, integer-heavy, and content-creation workloads, while Intel counters in specialized math, encryption, and single-threaded responsiveness.

The AMD Ryzen AI 9 HX PRO 370 is the clear choice for multi-core rendering and data processing. Its Cinebench R23 multi-core score of 18520 versus 14655 for the Intel part represents a 26.4% lead. The gap expands further in Cinebench R15 multi-core, where AMD leads by 45% (3178 versus 2192). In PassMark integer math, the AMD processor is 68.6% ahead, scoring 120016 against 71164. Data compression also favors AMD by 31.3% (403113 versus 307094). These results indicate a processor built to sustain heavy parallel workloads over long durations.

The Intel Arc G3 EXTREME takes the opposite side of the ledger. It wins PassMark single-thread by 6.8% (4293 versus 4003). It also leads in find prime numbers by 47.2% (248 versus 131), floating point math by 15.5% (86929 versus 73493), and physics by 24.8% (2515 versus 1892). Data encryption is another Intel win, with a 13% advantage (23881 versus 20788). These are not trivial margins; they indicate a different execution style that favors specific instruction patterns over raw thread count.

For users running database queries, video encoding, or 3D scene rendering, the AMD part is the stronger tool. For users running encryption, scientific floating-point simulations, or physics calculations, the Intel part holds the advantage. The average benchmark score paints the overall picture: AMD sits at 50448 versus Intel at 36699, a substantial gap that places the AMD part in the 90th percentile of all CPUs, while the Intel part sits at the 85th percentile.

Architecture Differences

The two processors come from opposite design philosophies. The AMD Ryzen AI 9 HX PRO 370 uses a 12-core, 24-thread layout based on the Zen 5 architecture, codenamed Strix Point. It belongs to the Ryzen AI PRO 300 generation, which mixes Zen 5 and Zen 5c cores. The process node is 4 nm, fabricated by TSMC, with a die size of 233 mm². The Intel Arc G3 EXTREME uses a 14-core, 14-thread layout with no hyperthreading, built on the Panther Lake codename under the Arc G3 generation. Its process node is 3 nm, fabricated by Intel, and no die size is recorded.

Cache organization differs sharply. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part has more total cache per core, but the AMD part relies on simultaneous multithreading to extract more work from each physical core.

Memory support also diverges. AMD supports both DDR5 and LPDDR5X in a dual-channel configuration, with a memory bandwidth of 89.6 GB/s. Intel supports only LPDDR5X, also dual-channel, but with a higher bandwidth of 136.5 GB/s. That bandwidth advantage likely contributes to Intel's wins in floating point and physics, which are memory-sensitive.

ECC memory is present on the AMD part but absent on the Intel part. PCIe connectivity differs as well: AMD uses Gen 4 with 16 lanes, while Intel uses Gen 5 but only 4 lanes. The integrated graphics are Radeon 890M on the AMD side and Arc B390 on the Intel side. Both are mobile processors, both are active in production, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The largest single win for AMD is in PassMark integer math, where the 120016 score beats Intel's 71164 by 68.6%. This is the kind of result that shows up in everyday productivity, code compilation, and spreadsheet-style workloads. The second largest AMD win is in Cinebench R15 multi-core, with a 45% margin (3178 versus 2192). Cinebench R23 multi-core follows at 26.4% (18520 versus 14655). Data compression shows a 31.3% edge for AMD (403113 versus 307094). Extended instructions favor AMD by 17.3% (28165 versus 24017). Random string sorting goes to AMD by 17.2% (43767 versus 37331). PassMark multithread is closer, with AMD ahead by 8.8% (33349 versus 30659). Cinebench R15 single-core gives AMD a 15.7% win (309 versus 267), and R23 single-core is a narrower 7% AMD lead (1992 versus 1862).

Intel's biggest win is in find prime numbers, where it leads by 47.2% (248 versus 131). That is a massive margin in a test that stresses branch prediction and integer division. Physics follows with a 24.8% Intel advantage (2515 versus 1892). Floating point math goes to Intel by 15.5% (86929 versus 73493). Data encryption gives Intel a 13% edge (23881 versus 20788). Single-thread performance is also Intel's, though by a smaller 6.8% margin (4293 versus 4003 in both PassMark single-thread tests).

The pattern is consistent across repeated tests. The two PassMark single-thread entries are identical in both score and delta, confirming measurement stability. The AMD part wins all four Cinebench tests, while Intel wins four of the nine PassMark tests it appears in. The results are not close in many cases, and the direction of each win aligns with the architectural differences.
