45 t/s a second is perfectly respectable especially with no limits and 24/7 uptime with very little power draw on the Studio.

There's a ton of well-understood things Apple can and hopefully will do to massively accelerate every stage of this pipeline and hopefully they're hard at work implementing most of them for m7.
