Waitwaitwaitwaitwait, haha Intel did us dirty again. There is no performance improvement whatsoever, they just lowered the internal resolution. The 10% "performance improvement" is simply the difference between 2.0x and 2.3x upscaling. Malicious fuckers.
There may be a quality improvement but that cannot be determined by anyone affiliated with Intel as they're clearly using every opportunity to lie about this. WTF?
