Intel Arc G3 EXTREME vs Intel Core 3 100U Comparison

Head-to-Head Benchmarks

The benchmark data records 17 head-to-head comparisons between the Intel Arc G3 EXTREME and the Intel Core 3 100U, and the Arc G3 EXTREME wins every single one. This is not a close contest; the margins range from 22.4% to 376.9% depending on the workload.

The largest single advantage appears in the PassMark find prime numbers test, where the Arc G3 EXTREME scores 248 against 52 for the Core 3 100U, a 376.9% difference. This is an extreme outlier, but it points to a fundamental throughput advantage that carries across nearly every category. Floating point math shows a 206.9% gap, with scores of 86929 versus 28322. Extended instructions follow closely at 204.2%, with 24017 against 7894.

Multi-threaded workloads show consistent, large advantages. In Cinebench R20 multicore, the Arc G3 EXTREME scores 10945 versus 4462, a 145.3% lead. PassMark multithread shows 30659 against 12522, a 144.8% gap. Random string sorting delivers 37331 versus 15191, a 145.7% difference. Data compression shows 307094 versus 136497, a 125% lead. Data encryption is even more lopsided: 23881 versus 8128, a 193.8% gap. Physics simulation delivers 2515 versus 876, a 187.1% advantage.

The single-core picture is closer but still favors the Arc G3 EXTREME decisively. Cinebench R23 singlecore shows 1862 versus 1499, a 24.2% lead. PassMark single thread shows 4293 versus 3506, a 22.4% lead. Cinebench R20 singlecore shows 1545 versus 629, a 145.6% gap. The R15 singlecore test shows 267 versus 150, a 78% lead. Integer math shows 71164 versus 39580, a 79.8% gap. The narrowest margins are in the single-core workloads, which suggests the Core 3 100U is comparatively better at lightly threaded tasks than at heavily threaded ones, though it still loses every one of those tests.

Cinebench R23 multicore shows the smallest overall gap among the multi-thread tests: 14655 versus 10624, a 37.9% lead. This is interesting because the R20 multicore gap is 145.3%, meaning the relative difference shrinks substantially in the newer Cinebench version. The absolute scores are higher for both parts in R23, but the Core 3 100U narrows the proportional gap. The data does not explain why this happens, but the recorded result is consistent.

The average benchmark score in the database places the Arc G3 EXTREME at 36699, against 16148 for the Core 3 100U. The percentile ranking reinforces the split: the Arc G3 EXTREME sits at the 85th percentile of all CPUs, while the Core 3 100U sits at the 70th percentile. The nearest rivals for the Arc G3 EXTREME are the Intel Core Ultra 5 225 at 36938, AMD Ryzen 5 5600F at 36945, AMD Ryzen 5 5500X3D at 37018, and AMD Ryzen AI 7 PRO 450 at 37093. The delta percentages are -0.6, -0.7, -0.9, and -1.1 respectively, meaning the Arc G3 EXTREME trails each by less than 1.1%. For the Core 3 100U, the nearest rivals are the Intel Core i7-10850H at 16204 (-0.3%), Intel Core i5-10600KF at 16228 (-0.5%), Intel Core i7-1260U at 16320 (-1.1%), and AMD Ryzen 5 4600H at 16341 (-1.2%).

Where Each One Wins

The Arc G3 EXTREME wins in every recorded benchmark category, so the use-case split is defined by the magnitude of the advantage rather than by which processor wins. For heavily parallel workloads, the Arc G3 EXTREME is in a different class. Data encryption, extended instructions, floating point math, and physics simulation all show gaps above 187%. Any workload that scales across cores will favor the Arc G3 EXTREME by a wide margin.

The Core 3 100U is not without a role in the data. Its largest relative strengths appear in single-core tests and in Cinebench R23 multicore, where the gaps are 22.4%, 24.2%, and 37.9% respectively. These are still losses, but they are the closest results in the entire comparison. For workloads that are lightly threaded, such as older applications or tasks with strict single-thread dependencies, the Core 3 100U comes closer to matching the Arc G3 EXTREME. The database shows a 22.4% gap in PassMark single thread, which is far smaller than the 193.8% gap in data encryption.

The Core 3 100U also has a lower TDP of 15 watts against 25 watts. This does not appear in benchmark scores directly, but it is a recorded specification that affects where each part might be deployed. The Arc G3 EXTREME delivers higher performance at a higher power envelope; the Core 3 100U delivers less performance at a lower power envelope.

Architecture Differences

The two processors come from different Intel generations and use different process nodes. The Arc G3 EXTREME uses the Panther Lake codename, with a 3 nm process node and a generation label of Arc G3 (Panther Lake). The Core 3 100U uses the Raptor Lake-U codename, with a 10 nm process node and a generation label of Core 3 (Raptor Lake-U). The process node difference is substantial: 3 nm versus 10 nm.

Core counts differ sharply. The Arc G3 EXTREME has 14 cores and 14 threads, meaning it has no hyperthreading. The Core 3 100U has 6 cores and 8 threads, indicating that two of its cores support hyperthreading. The Arc G3 EXTREME also has a higher base clock of 1.90 GHz versus 1.20 GHz, while both parts boost to 4.70 GHz.
