I mean, come on. Ars's 933 minute number was already insane. Over fifteen and a half hours! And now it's over an hour more than that.
Interestingly, the already abysmal effect WebGL had has year has gotten even worse.
Presumably, this is because the models start at a 555 and go up to a 560 now, whereas previously, they were available in 450, 455 and 460 configurations. I'm guessing the 450 (and would-be 550) are lower-wattage?
Either way, it's unfortunate that the tbMBPs are so dGPU-dependent again. I'm guessing Apple's hands are tied on that, since Intel apparently isn't interested in the Iris Pro any more.
