Yes according to NBC the P13/16 variant of HX370 scored that, but the S16 variant, the one tested by Intel and why I restricted the final chart to only that number, only got 67.9FPS though Intel claimed their S16 did 83. NBC's S16 had lower performance in general than the HX370 in the P13/16 (with a few exceptions where it matched or beat it). Regardless the main point was to show testing at 1080p medium can skew the results to allow a weaker GPU to catch up to a bigger one.
This shows up in your chart as well comparing low, medium, high, and ultra performance the M3 10-core does much better the lower the graphics setting as the strength of Apple's CPU begins to outmuscle AMD's. So it is entirely possible that Intel wins at medium but gets progressively worse at high and ultra relative to the AMD chip. Also from NBC's analysis, the previous Intel GPU, which may have different behavior, scored much worse than linear scaling at lower TDP. Since Intel only showed results from its highest GPU configuration, it is unclear how a more comparable GPU to the M3 in terms of power would perform - i.e. the Ultra 5 226/228V.
Thanks! I was wondering about the test details and didn't see slide 87. So as usual they have compared with the weaker AMD 890M to get 16% better results.
