Intel Arc G3 EXTREME vs Intel Core Ultra 7 258V Comparison

The Intel Arc G3 EXTREME and the Intel Core Ultra 7 258V are both mobile processors from Intel, but they target distinctly different performance profiles. The database records show the Arc G3 EXTREME winning 15 of the 17 head-to-head benchmark comparisons, with the Core Ultra 7 258V taking only 2 wins. This split is not merely a matter of overall speed; the two chips diverge sharply depending on whether the workload scales with core count or relies on single-thread efficiency.

Where Each One Wins

The Intel Arc G3 EXTREME is the clear winner in heavily threaded and throughput-oriented tasks. Its 14 cores and 14 threads give it a substantial structural advantage over the 8-core, 8-thread Core Ultra 7 258V. This shows in multi-core rendering, where the Arc G3 EXTREME leads by wide margins in Cinebench R15, R20, and R23 multicore tests. The same pattern repeats across PassMark’s workload suite: integer math, floating point math, data compression, data encryption, extended instructions, physics, random string sorting, and multithreaded performance all favor the Arc G3 EXTREME by margins ranging from 34.1% to 76.5%.

The Core Ultra 7 258V wins only in two narrow single-core scenarios. It takes the Cinebench R15 single-core test by 6.3% and the Cinebench R23 single-core test by a small 0.5% margin. In the PassMark single-thread test, the Arc G3 EXTREME actually wins, scoring 4293 against 4018, a 6.8% advantage. So the Core Ultra 7 258V’s wins are confined to specific legacy or lightly threaded Cinebench runs, not a general single-thread superiority.

The overall average benchmark scores reflect this gap. The Arc G3 EXTREME posts an average benchmark score of 36699, placing it in the 85th percentile of all CPUs in the database. The Core Ultra 7 258V averages 20454, which lands in the 74th percentile. The Arc G3 EXTREME’s nearest rivals are the Intel Core Ultra 5 225, AMD Ryzen 5 5600F, AMD Ryzen 5 5500X3D, and AMD Ryzen AI 7 PRO 450, all within a 1.1% delta of its average score. The Core Ultra 7 258V sits near the AMD Ryzen 5 5600, AMD Ryzen 5 8500G, AMD EPYC 9454P, and AMD EPYC 7713, with deltas of 0.4% or less.

The Verdict

The data indicates that the Intel Arc G3 EXTREME is the appropriate choice for workloads that use multiple cores, such as video encoding, 3D rendering, software compilation, or data processing. Its 14 cores deliver consistent, large advantages across the entire PassMark multithreaded suite and all three Cinebench multicore tests. The 85th percentile ranking versus the 74th percentile ranking also confirms that the Arc G3 EXTREME sits higher in the overall performance distribution.

The Intel Core Ultra 7 258V is the better option only when the application is strictly single-threaded and specifically sensitive to the Cinebench R15 or R23 single-core scoring method. In those two tests, it edges out the Arc G3 EXTREME, but the margins are small, especially in R23 where the difference is 0.5%. The PassMark single-thread test, which is a broader measure, shows the Arc G3 EXTREME ahead by 6.8%. Therefore, the Core Ultra 7 258V offers no consistent single-thread advantage across the full benchmark set.

For a mobile system where sustained multi-core throughput matters, the Arc G3 EXTREME is the stronger processor according to the recorded measurements. The Core Ultra 7 258V makes sense only for users who prioritize the specific single-core Cinebench results and do not need the Arc G3 EXTREME’s dominant multi-threaded performance.

Head-to-Head Benchmarks

The largest single win for the Intel Arc G3 EXTREME comes in PassMark data encryption, where it scores 23881 versus 13534, a 76.5% advantage. Data compression follows closely, with the Arc G3 EXTREME at 307094 against 176686, a 73.8% lead. Random string sorting shows a 73% delta, with scores of 37331 and 21580. These three tests all involve heavy data movement and parallel processing, which aligns with the Arc G3 EXTREME’s higher core count.

Integer math performance favors the Arc G3 EXTREME by 65.9%, with scores of 71164 versus 42889. Extended instructions show a 63.2% lead, and the Cinebench R20 multicore test shows a 62.4% delta. The PassMark multithread test records a 62.3% advantage. Physics simulation, which is often multi-threaded, gives the Arc G3 EXTREME a 60.7% lead, scoring 2515 against 1565. Floating point math shows a 51.5% delta, with scores of 86929 and 57372.

The Cinebench R23 multicore test, which is a common rendering benchmark, shows the Arc G3 EXTREME at 14655 versus 10301, a 42.3% lead. The Cinebench R15 multicore test shows a 37.3% delta, with scores of 2192 and 1596.5. Prime number finding gives the Arc G3 EXTREME a 34.1% advantage, scoring 248 versus 185.

The Core Ultra 7 258V’s wins are limited to the two Cinebench single-core tests. In Cinebench R15 single-core, it scores 285 versus 267, a 6.3% lead. In Cinebench R23 single-core, it scores 1872 versus 1862, a 0.5% lead. Notably, the Cinebench R20 single-core test goes the other way, with the Arc G3 EXTREME winning 1545 to 951, a 62.5% delta. This inconsistency suggests the Core Ultra 7 258V’s single-core wins are workload-specific rather than a general trait.

The PassMark single-thread test, which appears twice in the data with identical scores, shows the Arc G3 EXTREME ahead at 4293 versus 4018, a 6.8% advantage. This is a meaningful counterpoint to the Core Ultra 7 258V’s Cinebench single-core wins, as it indicates that the Arc G3 EXTREME is not universally slower in single-threaded work.
