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:

GFXBenchmark 2.7 T-Rex HD

GFXBenchmark 2.7 T-Rex HD - 4X MSAA

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.

    Nvidia Kepler plays Crysis 3 well but it sucks insanely hard at computing and rendering. Reply

    It appears to do compute better then graphics (and ECC memory is a plus for compute). That is exactly what pros will be looking for. Apple doesn't cater to the gaming market with these machines even if they should play most games fine. A dedicated gaming machine would be built much different then this. Reply

    This, I dont know about anyone else, but i'm not dropping 2 grand or $2700 with upgrades on a 15 incher that does not have dedicated graphics.

    Another problem i see is the 13" Retina only uses duals, and if they did use this quad with GT3e silicon, then the price of of the 13" will go up at least $150 since the i7's and i5's the 13" currently use, are sub $300 parts.

    The only solution i see is Apple offering it as a build to order/max upgrade option, and even then they risk segmentation across the product line.

    "can't sell a $2000 laptop without a dedicated GFX". Absolutely true, especially when the GT3e is still a little slower than the 650M. So the 750M tweaked a few mhz higher will do nicely for the rMBP. The 13 incher will get a boost with the GT3e CPU. So a slight upgrade to lower power cpu maybe worthwhile to some. Improvement to 1080p eyesight camera would be a given for the new rMBP. Reply

    You can drop discrete graphics when that $2000+ laptop is using builtin graphics with the same price premium and number of transistors of the discrete chip. I'm almost positive the discrete will go away. I have a feeling that Apple had a say in optimizations and stressed OpenCL performance. That is probably what they will highlight when they announce a new MacBook Pro. Reply

    I really hope that Apple continues to treat the rMBP 15 as a flagship. Giving it iGPU only would be a deal breaker for many professionals. Atleast in haswell's current form. Until Intel can make an IGPU that atleast matches or exceeds performance at high resolutions, it is still a no go for me. Reply

    Why is that a deal breaker? The Iris 5200 is better then a discrete chip for compute (OpenCL). If you are doing 3D rendering, video editing, photoshop, bioinformatics, etc. that is what you should care about. It also has ECC memory unlike a discrete chip so you know your output is correct. How fast it can texture triangles is less important. It still has plenty of power in that area for any pro app. This is not designed to be a gaming machine. Not sure why anyone would be surprised it may not be optimized for that. Reply

    You never know, but I doubt it. They will have trouble with the ports on the side if they make it smaller. I think it is more likely the space saving will go to additional battery. They may be able to get similar battery life increases to the Air with the extra space. Reply

    Notice that the 13" 2012 rMBP is a little thicker than the 15" version. Quad core in 13 inch may be planned at the very beginning. Reply

    Look at the overheating issues that come with i5/i7 Razer notebooks and finding the same heating noticed in their Haswell notebook press event several days ago.

    If Apple decides to use these Haswells which put out heat in a concentrated area and in very thin outlines, you are essentially computing over a mini-bake oven.
