Intel Arc G3 EXTREME vs Intel Core Ultra 9 285H Comparison

Head-to-Head Benchmarks

The recorded data sets up a clear hierarchy between these two mobile processors. The Intel Core Ultra 9 285H wins 16 of the 17 shared benchmark comparisons, while the Intel Arc G3 EXTREME secures a single, narrow victory. The overall average benchmark score places the Ultra 9 285H at 38312, roughly 4.4% ahead of the Arc G3 EXTREME's 36699.

The most dramatic separation appears in multi-core rendering workloads. In Cinebench R23 multi-core, the Ultra 9 285H scores 20781.5 against 14655 for the Arc G3 EXTREME, a 29.5% deficit for the latter. Cinebench R15 multi-core shows an even larger gap, with the Ultra 9 285H at 3177.5 versus 2192, a 31% difference. The R20 multi-core test narrows that margin considerably: 12201 against 10945, a 10.3% gap. This pattern suggests the Ultra 9 285H scales better as the workload grows in duration and thread count.

Single-core performance also favors the Ultra 9 285H, though by smaller margins. Cinebench R23 single-core shows 2129.5 against 1862, a 12.6% lead. The R20 single-core test records 1722 versus 1545, again 10.3%. R15 single-core shows 313 versus 267, a 14.7% advantage. PassMark single-thread results compress the difference to just 2.8%, with scores of 4415 and 4293. The boost clock difference likely explains part of this: the Ultra 9 285H boosts to 5.40 GHz while the Arc G3 EXTREME reaches 4.70 GHz.

PassMark integer math favors the Ultra 9 285H by 17.2%, with 85922 against 71164. Floating-point math shows a 20.4% lead for the Ultra 9 285H, scoring 109190 versus 86929. Prime number finding, a workload sensitive to memory latency and core efficiency, gives the Ultra 9 285H a 24.8% edge at 330 versus 248. Data compression shows an 8.6% lead for the Ultra 9 285H (335859 against 307094), and data encryption matches that 8.6% delta (26140 versus 23881).

The single win for the Arc G3 EXTREME comes in PassMark physics, where it scores 2515 against 2513 for the Ultra 9 285H, a 0.1% margin. That difference is statistically negligible and likely within run-to-run variance. Extended instructions and random string sorting both favor the Ultra 9 285H by 10.4% and 8.8% respectively. PassMark multithread shows a 10.3% lead for the Ultra 9 285H, with 34171 against 30659.

The percentile ranking places the Ultra 9 285H at the 86th percentile of all CPUs, one point above the Arc G3 EXTREME at the 85th percentile. Despite the consistent benchmark losses, the Arc G3 EXTREME sits close to several rivals: Intel Core Ultra 5 225 (delta -0.6%), AMD Ryzen 5 5600F (delta -0.7%), AMD Ryzen 5 5500X3D (delta -0.9%), and AMD Ryzen AI 7 PRO 450 (delta -1.1%). The Ultra 9 285H clusters with Intel Core 9 270H (delta -0.1%), Intel Core i5-13600HX (delta 0.1%), Intel Xeon w3-2525 (delta -0.2%), and AMD Ryzen 7 250 (delta 0.2%).

Where Each One Wins

The Intel Core Ultra 9 285H dominates every meaningful performance category in the dataset. For multi-threaded productivity, rendering, and compilation workloads, the Cinebench results show a consistent 10% to 31% advantage depending on the test generation. The Ultra 9 285H also takes every PassMark compute workload: integer math, floating-point math, prime numbers, encryption, compression, extended instructions, and random string sorting. Its single-thread scores lead in all recorded tests, making it the stronger choice for lightly threaded applications such as legacy software, spreadsheet recalculation, and general desktop responsiveness.

The Intel Arc G3 EXTREME wins exactly one benchmark: PassMark physics, with a 0.1% margin. This suggests parity in physics simulation workloads, likely because that test does not scale with the additional cores and threads available on the Ultra 9 285H. The Arc G3 EXTREME also has a lower TDP of 25 watts against 45 watts for the Ultra 9 285H, so it may sustain similar physics performance while drawing less power. However, the data does not include power efficiency measurements, only the rated TDP figures.

For users prioritizing raw compute throughput, the Ultra 9 285H is the clear winner across the board. The largest deltas appear in multi-core rendering (31% in R15, 29.5% in R23), while the smallest deltas appear in single-thread PassMark (2.8%). The Arc G3 EXTREME does not win any rendering, encryption, compression, or math workload. Its only relevance in a head-to-head comparison is the physics test and the lower power envelope.

The Verdict

The benchmark data indicates that the Intel Core Ultra 9 285H is the superior processor for nearly all measured workloads. Its 16 wins against 1 loss, combined with the 86th percentile ranking and higher average score of 38312, position it as the more capable part. The largest advantages come in multi-threaded rendering, where the 16 cores and 16 threads of the Ultra 9 285H outperform the 14 cores and 14 threads of the Arc G3 EXTREME by margins up to 31%.

The Arc G3 EXTREME, despite its newer Panther Lake architecture and 3 nm Intel process, trails in every compute benchmark except physics. Its 25 watt TDP suggests a lower-power design, but the database records no efficiency metrics to confirm that advantage in practice. The Ultra 9 285H carries a 45 watt TDP and a 5.40 GHz boost clock, which explains its consistent single-thread and multi-thread leads. The launch MSRP for the Ultra 9 285H is $651.

For workloads that demand maximum multi-core throughput, the Ultra 9 285H is the definitive pick. For scenarios where physics simulation is the primary task, the two processors are effectively tied. The Arc G3 EXTREME offers no other measurable benefit in this dataset. Users constrained by power budgets might consider the Arc G3 EXTREME based on its lower TDP, but the recorded performance data does not quantify the trade-off.
