Intel Arc G3 vs Intel Core Ultra 7 255H Comparison

The Intel Arc G3 and the Intel Core Ultra 7 255H are both mobile processors from Intel, but they occupy different positions in the database. The Arc G3, part of the Panther Lake generation, has no recorded benchmark scores and sits at the 50th percentile of all CPUs. The Core Ultra 7 255H, built on Arrow Lake, has an extensive set of measurements, an average benchmark score of 33537, and ranks at the 83rd percentile. The data confirms that the Core Ultra 7 255H is the only one of the two with verified performance results, making it the clear choice for any workload where measured output matters. The Arc G3, without benchmark data, cannot be positioned against it on any performance metric. The Core Ultra 7 255H also has a higher core count, higher clocks, more cache, and broader memory support. The Arc G3 does have a higher recorded memory bandwidth and a smaller process node attribution, but the absence of benchmark results limits its practical appeal.

The Verdict

The recorded data points to the Intel Core Ultra 7 255H as the processor with measurable performance. It has 16 cores and 16 threads, a base clock of 2.00 GHz, and a boost clock of 5.10 GHz. Its average benchmark score is 33537, placing it at the 83rd percentile of all CPUs. The Intel Arc G3 has 14 cores and 14 threads, a base clock of 1.90 GHz, and a boost clock of 4.60 GHz. Its average benchmark score is 0, with no benchmark entries in the database. The Core Ultra 7 255H delivers every recorded score in this comparison. The Arc G3 does not have a single measured result to analyze.

For users selecting between these two based strictly on database information, the Core Ultra 7 255H is the only option with proven performance. Its nearest rivals in the database include the AMD Ryzen 5 240 with an average score of 33542 and a delta of 0 percent, the AMD Ryzen 7 8840HS with a score of 33667 and a delta of -0.4 percent, and the AMD Ryzen 5 7645HX with a score of 33668 and a delta of -0.4 percent. The Core Ultra 7 255H is within 0.5 percent of the Intel Core i5-12600HX, which scores 33375. This places it in a competitive band with those processors, all of which have measured results.

The Arc G3, by contrast, has no rivals listed and no benchmark scores. Its percentile of 50 is the default position for a processor without recorded data. The verdict is straightforward: the Core Ultra 7 255H is the processor with data-backed capability, while the Arc G3 remains unverified in this database.

Where Each One Wins

The Core Ultra 7 255H wins in every measured category because it is the only processor with benchmark results. Its single-core performance is recorded across multiple tests. In Cinebench R15 single-core, it scores 251. In Cinebench R20 single-core, it scores 900. In Cinebench R23 single-core, it scores 1843. In Geekbench single-core, it scores 2335. In PassMark single-thread, it scores 4317. These results show consistent single-thread capability.

Multi-core performance is also fully documented for the Core Ultra 7 255H. Cinebench R15 multi-core yields 1515, Cinebench R20 multi-core yields 6381, and Cinebench R23 multi-core yields 9240. Geekbench multi-core records 14024, and PassMark multi-thread records 30703. The PassMark suite adds specific workload results: data compression at 298850, data encryption at 23395, extended instructions at 23755, find prime numbers at 303, floating point math at 98796, integer math at 77975, physics at 2254, and random string sorting at 36058.

The Arc G3 has no wins in any category because the database contains no scores for it. The use-case split is therefore one-sided. For any workload, whether single-threaded, multi-threaded, or specialized math operations, the Core Ultra 7 255H provides the only available numbers. The Arc G3 cannot be credited with any advantage in this comparison.
