Sourcing and disambiguation notes

Base power 28W, turbo up to 115W depending on chassis. Supports LPDDR5X-8400 (102.4 GB/s) or DDR5-6400 depending on OEM design - system RAM is shared with the Arc 140T iGPU (8 Xe2 cores), not dedicated VRAM. Representative laptop: LG Gram 15 (15Z90T-H.AAB4U1), Intel Core Ultra 7 255H, 16GB/1TB. Other 255H laptops in the same price list ranged roughly $1,300-$3,050 depending on RAM/GPU/storage -- this is toward the low end of that range.

Measurements

Decode is token generation — the speed you feel while an answer streams. Prefill is prompt processing — the wait before it starts. Why bandwidth predicts decode speed.

What verified, single-source and estimated mean, and the same rows with every filter and sort in the benchmarks explorer.

Speed over time

What it can run

Fit is arithmetic, not a measurement — how it is computed. Against 32 GB; models that fit are listed largest first.
