Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested
by Anand Lal Shimpi on June 1, 2013 10:01 AM ESTGRID 2
GRID 2 is a new addition to our suite and our new racing game of choice, being the very latest racing game out of genre specialty developer Codemasters. Intel did a lot of publicized work with the developer on this title creating a high performance implementation of Order Independent Transparency for Haswell, so I expected it to be well optimized. I ran out of time in testing this one and couldn't include all of the parts here. I did use GRID 2 as an opportunity to look at the impact of MSAA on Iris Pro's performance.
Without AA, Iris Pro does well, with the 650M pulling ahead by low double digits. Mobile Trinity is roughly half the speed of Iris, with desktop Trinity bridging the gap.
Turn up the resolution, add AA, and NVIDIA pulls ahead by a large margin. The desktop Trinity part also inches ahead.
Ramp up the quality settings however and Iris Pro ends up ahead of the GT 650M. Desktop Trinity falls behind considerably, likely running into memory bandwidth limitations. Crystalwell seems to save Iris Pro here.

They are completely different systems making power consumption values irrelevant.codedivine - Saturday, June 1, 2013 - link
Hi folks. Can you post the OpenCL extensions supported? You can use something like "GPU Caps viewer" from Geeks3d.tipoo - Saturday, June 1, 2013 - link
Interesting that the compute is punches above it's game performance weight. I wonder if they could put more EUs in a chip, maybe a larger eDRAM, and put it on a board as a compute card.lmcd - Saturday, June 1, 2013 - link
They already have a compute card called Xeon Phi if I remember correctly.Klimax - Sunday, June 2, 2013 - link

I'm aware, but the Xeon Phi requires completely different programming than a GPU like this which can just use OpenCL.Soul_Master - Saturday, June 1, 2013 - link
What's your point for comparing desktop GPU with middle-range mobile GPU? CPU on both devices are not equal.Soul_Master - Saturday, June 1, 2013 - link
Sorry. I misunderstood about i7 4950HQ process, a high-end quad-core processor for laptops.Ryan Smith - Sunday, June 2, 2013 - link
It's what we had available. We wanted to test a DDR3 version of GK107, and that's what was on-hand.tipoo - Saturday, June 1, 2013 - link
Hmm, so it's heavily hinted at that the next rMBP will ditch discreet graphics. The 5200 is good, but that would still be a regression in performance. Not the first time Apple would have done that, there was the Radeon cut out of the Mini, the 320M to the 3000, even the bottom rung of the newest iMac with the 640m. I wonder if it would at least be cheaper to make up for it.
