The Verdict

The Intel Core Ultra 7 265KF is the clear performance leader in every measured workload. The data shows no benchmark category where the Arc G3 EXTREME comes out ahead. For any task that depends on CPU throughput, whether single-threaded or multi-threaded, the Core Ultra 7 265KF delivers substantially higher scores, with margins ranging from 12.9% in Passmark single-thread to 73.5% in Cinebench R23 single-core.

The Arc G3 EXTREME's position in the database is defined by its 85th percentile ranking and an average score of 36,699, which places it among mobile processors with modest power envelopes. Its nearest rivals, the Intel Core Ultra 5 225 and AMD Ryzen 5 5600F, sit within 0.7% of its average score, which indicates the Arc G3 EXTREME is competitive within its own segment. But that segment is clearly not the same one occupied by the Core Ultra 7 265KF, which competes with the AMD Ryzen 7 8840HX and Intel Xeon parts at the 94th percentile.

The 265KF is the choice for users who prioritize raw compute performance. Its 20 cores, 20 threads, and 5.50 GHz boost clock support the benchmark results, and its unlocked multiplier allows further tuning. The Arc G3 EXTREME, with 14 cores, 14 threads, and a 4.70 GHz boost clock, is a mobile part with an integrated Arc B390 GPU, which positions it for portable systems where the Core Ultra 7 265KF's desktop socket and 125 W TDP are not applicable. The data does not support any scenario where the Arc G3 EXTREME outperforms the Core Ultra 7 265KF.

Where Each One Wins

The Core Ultra 7 265KF wins in every benchmark category present in the comparison. Its largest advantages appear in Cinebench R23, both single-core (73.5%) and multi-core (70.5%), which makes it the stronger choice for rendering workloads and any application that scales with both core count and per-core speed. Passmark data compression (53.9% lead), extended instructions (55.9% lead), and floating point math (54.1% lead) all favor the Core Ultra 7 265KF by wide margins, indicating strong performance in scientific computing, encryption, compression, and integer-heavy tasks. The passmark multithread score (58,518 versus 30,659) and data encryption score (48,198 versus 23,881) reinforce this pattern.

The Arc G3 EXTREME shows no benchmark wins in the recorded data. Its closest relative performance appears in Passmark single-thread, where it trails by only 12.9%, and in Passmark physics, where it trails by 30.8%. Those are the two areas where the mobile part is least disadvantaged, which suggests its per-core architecture is comparatively competent even if the aggregate results are far behind. The Arc G3 EXTREME also has a higher memory bandwidth figure (136.5 GB/s versus 102.4 GB/s) and an integrated Arc B390 GPU, which are advantages in the recorded specifications even though they do not appear in the CPU benchmark results.

The use-case split is therefore defined by platform rather than by performance victories. The Core Ultra 7 265KF is the appropriate selection for desktop builds requiring maximum CPU compute, with its 20 cores, 5.50 GHz boost, 30 MB L3 cache, and 20 PCIe Gen 5 lanes. The Arc G3 EXTREME is a mobile part with a 25 W TDP, 4.70 GHz boost, 18 MB L3 cache, and 4 PCIe Gen 5 lanes. In every recorded benchmark, the Core Ultra 7 265KF delivers the higher score. The Arc G3 EXTREME's role is limited to mobile systems where the Core Ultra 7 265KF's desktop socket and 125 W power draw are not viable. The data provides no other basis for choosing the Arc G3 EXTREME.
