Intel Arc B390 “Panther Lake” iGPU shows promising results in alleged 3DMark tests

Arc B390 tested in 3DMark

Leaker shares first synthetic test results.

First, let’s recap what Intel has already said about Xe3 performance. Officially not much, but we did learn that Xe3 should be above 50% faster than Lunar Lake (using Xe2) and at least 40% more power efficient than Arrow Lake-H (Xe with XMX). Anything above those numbers would be even better to hear, but we are used to seeing official slides usually exceeding expectations.

Unofficially, we know that Intel Panther Lake is already sampling and it should enter final mass production soon or already has. We also know that Raichu has access to one of these pre-production units, and it looks to be near-final silicon.

Raichu posted a cryptic message on X/Twitter with a score for what seems to be Time Spy Graphics. We reached out for confirmation and not only did the leaker confirm it is for this benchmark, we also confirmed it is for Arc B390 , the highest integrated graphics in the Panther Lake series.

Obviously, we immediately made a chart to better understand where this core sits. It seems to be twice as good as Radeon 890M and almost twice as good as Lunar Lake:

We know that Time Spy is not the best benchmark around these days and it also favors Intel chips, so we asked for another benchmark and Raichu also revealed that B390 can score 6000+ points in Steel Nomad Light. This is 87%+ higher than the average score for 890M and 80% above Arc 140T.

But we did not put performance figures into the title for a good reason. Raichu has not revealed the settings for the unnamed Panther Lake processor. For all we know, it could be running at 60W+ and end up much faster than it will in normal systems.

Still, this means that the 50%+ figure presented by Intel is very likely true and we may finally have some very interesting chip for gaming. As we also revealed, Intel is working on a special version for handheld gaming systems , which will also feature full 12 Xe3 graphics. Should AMD start to worry? Or perhaps ASUS should start thinking about lowering prices for ROG Xbox Ally?
