The Verdict

Benchmark data indicates the Arc G3 EXTREME is the stronger overall processor, with an average score of 36699 versus 34485 for the Ultra 5 336H. The Arc G3 EXTREME also sits at the 85th percentile among all CPUs, one point above the Ultra 5 336H's 84th percentile. The Arc G3 EXTREME wins 10 of 17 direct comparisons, including every PassMark test in its winning set except for the three noted earlier. Its wins in integer math, encryption, and data compression are decisive, ranging from 9.5 percent to 14.7 percent.

The Ultra 5 336H, however, delivers a far stronger result in Cinebench R23, the modern multi-threaded workload in the database. Its 23991 multi-core score is 63.7 percent higher than the Arc G3 EXTREME's 14655. This is not a marginal difference. The R23 single-core result is similarly lopsided, with the Ultra 5 336H scoring 3387 versus 1862, a 45 percent gap. For users prioritizing Cinebench R23 performance, the Ultra 5 336H is the clear choice.

The Arc G3 EXTREME's higher memory bandwidth (136.5 GB/s versus 115.2 GB/s) and higher boost clock (4.70 GHz versus 4.60 GHz) align with its PassMark strengths. The Ultra 5 336H's two additional cores and wider PCIe allocation (12 lanes versus 4 lanes) support its R23 dominance. The data does not show a single superior processor across all workloads. The Arc G3 EXTREME excels in integer-heavy and encryption workloads, while the Ultra 5 336H excels in rendering and single-core Cinebench tasks.
