The Verdict
The recorded data indicates a clear split between these two processors by market segment and workload profile. The Intel Core Ultra 3 105UL is the only one of the two with benchmark results in the database. Its average benchmark score of 13061 places it at the 68th percentile among all CPUs, and it edges out several established desktop rivals. The Intel Arc G3, by contrast, has no recorded benchmark scores, so its performance cannot be quantified from the database; it remains at the 50th percentile by default.
For desktop users seeking a processor with measured multi-threaded and single-threaded results, the Intel Core Ultra 3 105UL is the only option with data. Its 8 cores and 10 threads, combined with a boost clock of 4.20 GHz, deliver a score of 8742 in Cinebench R23 multi-core and 1234 in single-core. The Arc G3 offers more cores (14) and a higher boost clock (4.60 GHz), but without benchmark results, the database cannot confirm how that translates into real-world performance.
The Arc G3 targets mobile systems with a 25 W TDP, LPDDR5X memory, and an integrated Arc B370 GPU. The Core Ultra 3 105UL targets desktops with a 15 W TDP, DDR5 memory, and an Arc Xe-LPG 48EU integrated GPU. Users on the desktop platform, particularly those building around Socket 1851, will find the Core Ultra 3 105UL to be the relevant choice. Mobile users would look to the Arc G3, but its absence of benchmark data means no performance verdict can be drawn from the database.
Head-to-Head Benchmarks
The database contains no direct head-to-head benchmark comparisons between the Intel Arc G3 and the Intel Core Ultra 3 105UL. The wins count for both processors is zero. This means there are no recorded side-by-side scores for the two in any common test.
The Intel Core Ultra 3 105UL does have a full set of benchmark results. Its Cinebench R23 multi-core score is 8742, and its single-core score is 1234. In Cinebench R20, it scores 3671 multi-core and 518 single-core. The older Cinebench R15 test shows 881 multi-core and 124 single-core.
PassMark results for the Core Ultra 3 105UL include a multithread score of 10285 and a single-thread score of 3382. Data compression scores 93961, data encryption scores 6354, and extended instructions score 5634. Floating point math reaches 30750, integer math reaches 41171, and physics scores 718. Random string sorting scores 11179, and find prime numbers scores 44.
The nearest rivals to the Core Ultra 3 105UL provide context for these numbers. The Intel Core i5-9400F scores 13041, which is 0.2% lower than the Core Ultra 3 105UL. The Intel Core i7-10750H scores 13024, 0.3% lower. The Intel Core i5-8500 scores 13142, which is 0.6% higher, and the Intel Core i7-7700K scores 13291, which is 1.7% higher. These deltas show that the Core Ultra 3 105UL sits in a tight cluster with four older desktop and mobile parts, all within roughly 2% of each other.
Because the Arc G3 has no benchmark entries, the head-to-head section cannot show any wins for it. The data available in the database only supports performance statements for the Core Ultra 3 105UL. The Arc G3's higher core count and boost clock suggest potential, but no measured scores exist to confirm it.
