Something easier to understand, perhaps, more direct performance working backwards from that chart.
(for a 24-core 1Ghz Larrabee)
F.E.A.R. 1600x1200 4xAA, frames per second per frame in the sample set (rounded figures)

Average FPS: 119.28
Minimum FPS: 55
Maximum FPS: 206
Median FPS: 103
So based on this tiny sample set, such a set up might be comparable to 3dilettante's GT200 figure, if not a bit (20+%) better.
