The Verdict

The benchmark data draws a clear line between two different workload profiles. The Intel Arc G3 EXTREME is the stronger all-around compute part in the PassMark suite, winning encryption, extended instructions, find prime numbers, floating point math, multithread, physics, random string sorting, and single-thread tests. Its 90.8% lead in find prime numbers and 31.6% lead in physics indicate that it handles dense iterative and physics-style workloads with less effort than the Core i5-14500HX.

The Intel Core i5-14500HX is the stronger rendering processor. Its Cinebench R23 results are decisive: a 39.5% multicore lead and a 45.6% single-core lead. It also wins Cinebench R15 by 10.2% multicore and 22.4% single-core, plus PassMark integer math by 25.5% and data compression by 8%. The R23 single-core margin is the second-largest gap in the entire comparison, which suggests a meaningful architectural advantage in lightly threaded render and simulation tasks.

The average benchmark score favors the Arc G3 EXTREME at 36699 versus 35094, a 4.6% difference, and the Arc G3 EXTREME sits one percentile point higher at 85 versus 84. The nearest rival data reinforces this: the Arc G3 EXTREME trails its closest rivals by less than 1.1%, while the Core i5-14500HX is within 0.5% of its nearest rivals in either direction. The Arc G3 EXTREME is effectively competing in a slightly higher performance tier by average score.

For buyers selecting based on measured results, the choice depends on which benchmark family matters more. If the workload is dominated by Cinebench-style rendering, the Core i5-14500HX is the clear pick. If the workload spans the broader PassMark compute set, the Arc G3 EXTREME offers more consistent wins and a higher average score.

Where Each One Wins

The Intel Arc G3 EXTREME wins in data encryption, extended instructions, find prime numbers, floating point math, PassMark multithread, physics, random string sorting, and PassMark single-thread. It also wins Cinebench R20 multicore and single-core. These results cover arithmetic-heavy workloads, encryption tasks, physics calculations, and general multithreaded throughput. The Arc G3 EXTREME also holds the higher average benchmark score, 36699, and the higher percentile ranking at 85.

The Intel Core i5-14500HX wins in Cinebench R15 multicore and single-core, Cinebench R23 multicore and single-core, PassMark integer math, and data compression. These wins are concentrated in render workloads and integer-driven tasks. The R23 multicore margin of 39.5% and single-core margin of 45.6% make it the dominant part for users running current-generation Cinebench loops. The data compression win at 333851 versus 307094 also points to an advantage in file compression and decompression pipelines.

The split is not subtle. The Arc G3 EXTREME wins 11 tests, the Core i5-14500HX wins 6. The Arc G3 EXTREME wins more tests overall, but the Core i5-14500HX wins the two largest individual margins. Users prioritizing Cinebench R23 results should favor the Core i5-14500HX. Users prioritizing PassMark compute breadth and average score should favor the Arc G3 EXTREME.
