Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested
by Anand Lal Shimpi on June 1, 2013 10:01 AM ESTSleeping Dogs
A Square Enix game, Sleeping Dogs is one of the few open world games to be released with any kind of benchmark, giving us a unique opportunity to benchmark an open world game. Like most console ports, Sleeping Dogs’ base assets are not extremely demanding, but it makes up for it with its interesting anti-aliasing implementation, a mix of FXAA and SSAA that at its highest settings does an impeccable job of removing jaggies. However by effectively rendering the game world multiple times over, it can also require a very powerful video card to drive these high AA modes.
At 1366 x 768 with medium quality settings, there doesn't appear to be much of a memory bandwidth limitation here at all. Vsync was disabled but there's a definite clustering of performance close to 60 fps. The gap between the 650M and Iris Pro is just under 7%. Compared to the 77W HD 4000 Iris Pro is good for almost a 60% increase in performance. The same goes for the mobile Trinity comparison.
At higher resolution/higher quality settings, there's a much larger gap between the 650M and Iris Pro 5200. At high quality defaults both FXAA and SSAA are enabled, which given Iris Pro's inferior texture sampling and pixel throughput results in a much larger victory for the 650M. NVIDIA maintains a 30 - 50% performance advantage here. The move from a 47W TDP to 55W gives Iris Pro an 8% performance uplift. If we look at the GT 640's performance relative to the 5200, it's clear that memory bandwidth alone isn't responsible for the performance delta here (although it does play a role).
Once more, compared to all other integrated solutions Iris Pro has no equal. At roughly 2x the performance of a 77W HD 4000, 20% better than a desktop Trinity and 40% better than mobile Trinity, Iris Pro looks very good.

I see Razer making an Edge tablet with an Iris-based chip. In fact, it seems built for that idea more than anything else. That or a NUC HTPC run at 720p with no AA ever. You've got superior performance to any console out there right now and it's in a size smaller than an AppleTV.So yeah, the next Razer Edge should include this as an optional way to lower the cost of the whole system. I also think the next Surface Pro should use this. So high end x86-based laptops with Windows 8 Pro.
And NUC/BRIX systems that are so small they don't have room for discrete GPU's.
I imagine some thinner than makes sense ultrathins could also use this to great effect.
All that said, most systems people will be able to afford and use on a regular basis won't be using this chip. I think that's sad, but it's the way it will be until Intel stops trying to use Iris as a bonus for the high end users instead of trying to put discrete GPU's out of business by putting these on every chip they make so people start seeing it CAN do a decent job on its own within its specific limitations.
Right now, no one's going to see that, except those few fringe cases. Strictly speaking, while it might not have matched the 650m (or its successor), it did a decent job with the 640m and that's a lot better than any other IGP by Intel.

You confused me here on these points:1) The NUC uses a 17W TDP chip and overheats. We're not going to have Iris in that form factor yet.
2) It would increase the cost of the Edge, not lower it. Same TDP problem too.
Otherwise I agree, this really needs to roll down lower in the food chain to have a serious impact. Hopefully they'll do that with Broadwell used by the GPU when the die area effectively becomes free thanks to the process switch.

So intel was right. Iris Pro pretty much matches a 650m at playable settings (30 fps +). Note that anandtech is being full of BullS**t here and comparing it to an OVERCLOCKED 650m from apple. Lets see, when intel made that 'equal to a 650m' claim it was talking about a standard 650m not an overclocked 650m running at 900/2500 (GDDR5) vs the normal 835/1000 (GDDR5 + boost at full, no boost = 735 mhz core). If you look at a standard clocked GDDR3 variant iris pro 5200 and the 650m are pretty much very similar (depending on the games) within around 10%. New Intel drivers should further shorten the gap (given that intel is quite good in compute).JarredWalton - Sunday, June 2, 2013 - link
http://www.anandtech.com/bench/Product/814For the games I tested, the rMBP15 isnt' that much faster in many titles. Iris isn't quite able to match GT 650M, but it's pretty close all things considered.

I will believe this about new Intel drivers when I see them. I seriously, genuinely hope they surprise me, though.dbcoopernz - Saturday, June 1, 2013 - link
Are you going to test this system with madVR?Ryan Smith - Sunday, June 2, 2013 - link
We have Ganesh working to answer that question right now.dbcoopernz - Sunday, June 2, 2013 - link
Cool. :)JDG1980 - Saturday, June 1, 2013 - link
I would have liked to see some madVR tests. It seems to me that the particular architecture of this chip - lots of computing power, somewhat less memory bandwidth - would be very well suited to madVR's better processing options. It's been established that difficult features like Jinc scaling (the best quality) are limited by shader performance, not bandwidth.The price is far steeper than I would have expected, but once it inevitably drops a bit, I could see mini-ITX boards with this become a viable solution for high-end, passively-cooled HTPCs.
By the way, did they ever fix the 23.976 fps error that has been there since Clarkdale?

Missing Remote reports that 23.976 timing is much better.http://www.missingremote.com/review/intel-core-i7-...
