So I was gonna get an m370x refurb model, but they ran out the day before I was ready for purchase. At the very least, I figured i'd buy the 2014 Iris Pro base model to test it out and see if it was any kind of match or upgrade from my original 650m model. Considering the 650m is dedicated and i've heard so much about Intel's iGPU was still somewhat behind and around a 640m model, I figured they would be pretty even. Apparently the extra half gig of ram Iris Pro is allowed to use now, coupled with another 8gb of system ram does alot when using FCPX, cuz the results were alot better than I expected. Bruce X Test - http://blog.alex4d.com/2013/10/30/brucex-a-new-fcpx-benchmark/ 650m - 1:24 seconds Iris Pro - 1:09 Layered EFX - 40 second 1080p clip with 2 transitions, CC, Underwater, Glow, Pan, Aged Film, & Focus 650m - 9:38 Iris Pro - 8:02 3D Atmosphere Title -10 seconds, same EFX used 650m - 11:00 Iris Pro - 6:24 CLG Trailer - simple trailer I did for fun, under 3 mins 650m - 8:34 Iris Pro - 5:49 At this point i'm wondering what upgrading to the m370x model will even do. The extra ram on both the system and iGPU, slightly faster CPU and better Open CL optimization seems to have done so much already. The system also seems to use the fans alot more. My 650m model seems to get really hot with the fans off more often, only cooling when it needs to, but the Iris Pro model seems to have the fans cranked alot more and keeping the system way cooler, albeit much louder. Just figured i'd post these results since i'm always told integrated will take a far back seat to dGPUs, but they seem to have come a long way.
