Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pair. The recorded wins are zero for each side. Because the Core Ultra 7 155UL has no benchmark scores, no direct delta can be computed between the two processors. The Arc G3 EXTREME's standalone results are the only measured data available in this comparison.

Cinebench results for the Arc G3 EXTREME: R15 multicore 2192, R15 singlecore 267, R20 multicore 10945, R20 singlecore 1545, R23 multicore 14655, R23 singlecore 1862. Passmark results: data compression 307094, data encryption 23881, extended instructions 24017, find prime numbers 248, floating point math 86929, integer math 71164, multithread 30659, physics 2515, random string sorting 37331, single thread 4293.

The average benchmark score for the Arc G3 EXTREME is 36699, which places it at the 85th percentile of all CPUs. For context, that average sits 0.6% below the Intel Core Ultra 5 225 (36938), 0.7% below the AMD Ryzen 5 5600F (36945), 0.9% below the AMD Ryzen 5 5500X3D (37018), and 1.1% below the AMD Ryzen AI 7 PRO 450 (37093). The Core Ultra 7 155UL has an average benchmark score of 0 and a 50th percentile standing, and no comparable processors are recorded for it.

Where Each One Wins

No benchmark wins are recorded for either processor. The recorded data therefore does not support a measured performance victory for either side. The Arc G3 EXTREME holds the only benchmark scores in the pairing, so it is the only processor with measurable wins in the database, albeit not against the Core Ultra 7 155UL. Its Cinebench R23 multicore score is 14655 and its Passmark multithread score is 30659. Its Passmark single thread score is 4293. These are the only data points that can be attached to a performance use case.

The Arc G3 EXTREME wins on specification fields relevant to heavy multi-threaded and memory-sensitive workloads: 14 cores versus 12, 18 MB shared L3 versus 12 MB, 136.5 GB/s memory bandwidth versus 89.6 GB/s, and a 3 nm process versus 7 nm. It is also the only part with recorded benchmark scores.

The Core Ultra 7 155UL wins on specification fields relevant to low-power desktop operation: 15 W TDP versus 25 W, 4.80 boost clock versus 4.70, 8 PCIe Gen 4 lanes versus 4 PCIe Gen 5 lanes, and a desktop socket (Intel Socket 1851) versus a mobile socket (Intel BGA 2540). Its release date of 2024-04-07 is earlier than the Arc G3 EXTREME's 2026-05-27. No benchmark scores exist for the Core Ultra 7 155UL, so its use case must be defined by specifications only. The data supports no performance win for the Core Ultra 7 155UL.
