Iris Pro vs ATI HD 5750 1GB card in 2010 iMac

[amt2002]

I'm thinking about replacing my mid-2010 27" 2.8 Quad-core i5 iMac (with ATI HD 5750 1GB gfx card) with a new base 15" Retina Macbook Pro with Iris Pro graphics.

Whilst all reviews/benchmarks compare this to the previous generation of macbook pro, I can't find any information about how it compares with the card in my iMac for playing games.

Worse / same / better / way better?

I like the graphics capabilities on the iMac so if Iris Pro matches these I'll be happy.

I'm fairly sure the Iris Pro will outperform the 5750. Max the ram out as the Iris Pro uses it.

Iris Pro is faster but not by a big margin as it is a Desktop GPU and even though it is old can old its ground okay. Iris Pro is definitely not slower, a 5750 is way to old for that and was never more than a cheap mainstream gpu.

from my experience owning one..... the iris runs circles around the 5700 series I have back then

It is a big difference in drivers and Iris support all the newest APIs and resolutions and media accelerations. In pure theoretical performance the 5750 is effectively a 74% faster 6750M (720vs 480 cores & 700 vs 600 mhz) which puts it somewhere close behind Iris Pro and a 650M.

It isn't slower but I have my doubts about the circles. There could be any number of differences in OSX OpenGL support and driver efficiency or comparing different systems when moving to SSD or newer OS Versions. The 3dmark results are from Windows obviously and those aren't the same drivers but still the speed of these two GPUs should be fairly close together.
