Funny as the AnandTech article wrote "Despite today being the official launch of the Core Ultra series and Meteor Lake platform, you won’t find any reviews for the hardware. And we’re not sure you’ll be able to find much hardware, either" and this YouTube channel reviews two such devices in their video. Benchmark data in the video:

Cinebench R23: 13218

Cinebench 2024: 701

Geekbench 6.2: 12319

Fire Strike GPU: 9317

Time Spy: 3283

Geekbench 6.2 Compute: 30101

Battery life (summary): In their various tests (not many apparent details on exactly how it was done) very comparable with the M2 air/7840U devices.

Gaming FPS (1080P Medium, iGPU): Generally better than the 780M

Overwatch 2: 82 FPS

Apex Legends: 73 FPS

Diablo 4: 50 FPS

Starfield: 31 FPS

Counter-Strike 2: 67 FPS

Valorant: 137 FPS

Executive summary (all numbers from the 155H part): Arc GPU looks fantastic and market-leading (though more so on rendering than compute, which I guess is to be expected since they're pushing the AI unit for those workloads?). Multicore CPU benchmarks running about 20-40% above the M2 Mac tested and 10% above AMD's 7840U. Battery life tests (a benchmark category I personally hate since it conflates so many different things) seem to have reached parity with the AMD and Apple devices, which doesn't sound notable but this was a BIG shortcoming with ADL/RPL.

On the whole... this sounds big. If these numbers check out in further testing then all of a sudden Intel's back on top of the laptop game.
