Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Testedby Anand Lal Shimpi on June 1, 2013 10:01 AM EST
3DMarks & GFXBenchmark
We don't use 3DMark to draw GPU performance conclusions but it does make for a great optimization target. Given what we've seen thus far, and Intel's relative inexperience in the performance GPU space, I wondered if Iris Pro might perform any differently here than in the games we tested.
It turns out, Iris Pro does incredibly well in all of the 3DMarks. Ranging from tying the GT 650M to outperforming it. Obviously none of this has any real world impact, but it is very interesting. Is Intel's performance here the result of all of these benchmarks being lighter on Intel's weaknesses, or is this an indication of what's possible with more driver optimization?
I also included GFXBenchmark 2.7 (formerly GL/DXBenchmark) as another datapoint for measuring the impact of MSAA on Iris Pro:
Iris Pro goes from performance competitive with the GT 650M to nearly half its speed once you enable 4X MSAA. Given the level of performance Iris Pro offers, I don't see many situations where AA will be enabled, but it's clear that this is a weak point of the microarchitecture.

Elitehacker - Tuesday, September 24, 2013 - linkEven for a given power usage the 650M isn't even to on the top of the list for highest end discrete GPU.... The top at the moment for lowest wattage to power ratio would be the 765M, even the Radeon HD 7750 has less wattage and a tad more power than the 650M. Clearly someone did not do their researching before opening their mouth.
I'm gonna go out on a limb and say that vFunct is one of those Apple fanboys that knows nothing about performance. You can get a PC laptop in the same size and have better performance than any Macbook available for $500 less. Hell you can even get a Tablet with an i7 and 640M that'll spec out close to the 650M for less than a Macbook Pro with 650M.
Eric S - Tuesday, June 25, 2013 - linkThe Iris Pro 5200 would be ideal for both machines. Pro users would benefit from ECC memory for the GPU. The Iris chip uses ECC memory making it ideal for OpenCL workloads in Adobe CS6 or Final Cut X. Discrete mobile chips may produce errors in the OpenCL output. Gamers would probably prefer a discrete chip, but that isn't the target for these machines.
Eric S - Monday, July 1, 2013 - linkI think Apple cares more about the OpenCL performance which is excellent on the Iris. I doubt the 15" will have a discrete GPU. There isn't one fast enough to warrant it over the Iris 5200. If they do ever put a discrete chip back in, I hope they go with ECC GDDR memory. My guess is space savings will be used for more battery. It is also possible they may try to reduce the display bezel.
emptythought - Tuesday, October 1, 2013 - linkIt's never had the highest end chip, just the best "upper midrange" one. Above the 8600m GT was the 8800m GTX and GTS, and above the 650m there was the 660, a couple 670 versions, the 675 versions, and the 680.
They chose the highest performance part that hit a specific TDP, stretching a bit from time to time. It was generally the case that anything which outperformed the MBP was either a thick brick, or had perpetual overheating issues.
CyberJ - Sunday, July 27, 2014 - linkNot even close, but whatever floats you boat.
emptythought - Tuesday, October 1, 2013 - linkIt wouldn't surprise me if the 15in just had the "beefed up" iris pro honestly. They might even get their own, special even more overclocked than 55w version.
Mainly, because it wouldn't be without precedent. Remember when the 2009 15in macbook pro had a 9400m still? Or when they dropped the 320m for the hd3000 even though it was slightly slower?
They sometimes make lateral, or even slightly backwards moves when there are other motives at play.
chipped - Sunday, June 2, 2013 - linkThat's just crazy talk, they want drop dedicated graphics. The difference is still too big, plus you can't sell a $2000 laptop without a dedicated GFX.
shiznit - Sunday, June 2, 2013 - linkconsidering Apple specifically asked for eDRAM and since there is no dual core version yet for the 13", I'd say there is very good chance.
mavere - Sunday, June 2, 2013 - link"The difference is still too big"
The difference in what?
Something tells me Apple and its core market is more concerned with rendering/compute performance more than Crysis 3 performance...
iSayuSay - Wednesday, June 5, 2013 - linkIf it plays Crysis 3 well, it can render/compute/do whatever intensive fine.
