Intel Arc G3 EXTREME vs Intel Core Ultra 9 185H Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive split between these two Intel mobile processors, with the Intel Arc G3 EXTREME winning 12 of the 17 recorded head-to-head comparisons. The Intel Core Ultra 9 185H takes the remaining five, but the magnitude of those victories is telling. The Arc G3 EXTREME's largest win is a 101.6% advantage in PassMark's find prime numbers test (248 vs. 123), a result that indicates substantially stronger single-thread integer throughput per core. The Core Ultra 9 185H counters with a 27.6% lead in PassMark integer math (98302 vs. 71164), showing that its higher core count and thread count matter in heavily parallel integer workloads.

Cinebench results are mixed. The Core Ultra 9 185H wins Cinebench R15 multicore by 21.8% (2801.5 vs. 2192) and Cinebench R23 multicore by 18.5% (17984.5 vs. 14655). However, the Arc G3 EXTREME wins Cinebench R20 multicore by 5.7% (10945 vs. 10356), a reversal that suggests the R20 workload responds differently to the two architectures. In single-core Cinebench tests, the Arc G3 EXTREME consistently leads: R15 by 0.9% (267 vs. 264.5), R20 by 5.7% (1545 vs. 1462), and R23 by 2.8% (1862 vs. 1810.5).

PassMark workloads further favor the Arc G3 EXTREME. It leads data encryption by 20.4% (23881 vs. 19827), extended instructions by 18.5% (24017 vs. 20272), floating point math by 18.6% (86929 vs. 73270), physics by 28.6% (2515 vs. 1956), multithread by 4.4% (30659 vs. 29376), and single-thread by 16.1% (4293 vs. 3697). The Core Ultra 9 185H wins data compression by 9.5% (339489 vs. 307094) and random string sorting by 5.7% (39598 vs. 37331).

The overall average benchmark scores place the Arc G3 EXTREME at 36699, which is 2.9% higher than the Core Ultra 9 185H's 35670. Both processors sit at the 85th percentile among all CPUs in the database. The Arc G3 EXTREME's nearest rivals include the Intel Core Ultra 5 225 (36938, 0.6% lower) and AMD Ryzen 5 5600F (36945, 0.7% lower). The Core Ultra 9 185H's nearest rivals include the AMD Ryzen AI 7 PRO 350 (35719, 0.1% lower) and Intel Core 7 250H (35728, 0.2% lower). These proximity scores indicate both chips are competitively positioned within their respective performance tiers.

Architecture Differences

The two processors come from different Intel generations and manufacturing nodes. The Arc G3 EXTREME uses the Panther Lake architecture on Intel's 3 nm process, while the Core Ultra 9 185H is built on Meteor Lake architecture at 7 nm. This node advantage likely explains the Arc G3 EXTREME's superior single-thread performance despite its lower boost clock of 4.70 GHz compared to 5.10 GHz on the Core Ultra 9 185H.

Core configurations differ substantially. The Arc G3 EXTREME has 14 cores and 14 threads, meaning no hyperthreading. The Core Ultra 9 185H has 16 cores and 22 threads, indicating a hybrid arrangement with hyperthreaded performance cores. Despite having fewer threads, the Arc G3 EXTREME wins the majority of benchmarks, including multithread tests (30659 vs. 29376). This suggests the Panther Lake cores are significantly more efficient per thread.

Cache hierarchies also diverge. The Arc G3 EXTREME has 192 KB L1 per core and 2.5 MB L2 per core, with 18 MB shared L3. The Core Ultra 9 185H has smaller per-core caches at 112 KB L1 and 2 MB L2, but a larger 24 MB shared L3. The total cache footprint favors the Core Ultra 9 185H, yet the Arc G3 EXTREME's larger per-core L1 and L2 likely contribute to its single-thread wins.

Memory bandwidth is another major differentiator. The Arc G3 EXTREME supports LPDDR5X with 136.5 GB/s bandwidth, while the Core Ultra 9 185H uses DDR5 (dependent on motherboard) with 89.6 GB/s. This 52.3% bandwidth advantage for the Arc G3 EXTREME helps explain its strong performance in memory-sensitive workloads like encryption and floating point math.

The integrated graphics differ as well: Arc B390 on the Arc G3 EXTREME versus Arc Xe-LPG Graphics 128EU on the Core Ultra 9 185H. Both are mobile parts, with the Arc G3 EXTREME using Intel BGA 2540 and the Core Ultra 9 185H using Intel BGA 2049. The Arc G3 EXTREME also has fewer PCIe Gen 5 lanes (4 vs. 8).

The Verdict

The data points to the Intel Arc G3 EXTREME as the stronger overall processor. It wins 12 of 17 head-to-head benchmarks, has a higher average benchmark score (36699 vs. 35670), and delivers superior single-thread performance across every recorded test. The 3 nm Panther Lake architecture provides clear efficiency advantages, reflected in its 25 W TDP versus 45 W for the Core Ultra 9 185H, while still winning multithread tests like PassMark multithread (30659 vs. 29376).

The Core Ultra 9 185H is not without merit. It wins Cinebench R15 and R23 multicore by substantial margins, dominates PassMark integer math by 27.6%, and handles data compression 9.5% better. These victories suggest it excels in specific heavily threaded integer and compression workloads. Its 24 MB L3 cache and 22 threads give it raw parallel capacity that the Arc G3 EXTREME cannot match in every scenario.

For users prioritizing single-thread responsiveness, encryption, floating point math, and physics simulations, the Arc G3 EXTREME is the clear choice. For those running long multi-core renders in Cinebench or integer-heavy data processing, the Core Ultra 9 185H offers measurable advantages. The Arc G3 EXTREME's overall benchmark superiority and architectural efficiency make it the recommended part for most mobile workloads, but the Core Ultra 9 185H remains competitive in its specific niches.
