Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested
by Anand Lal Shimpi on June 1, 2013 10:01 AM ESTCrysis 3
With Crysis 3, Crytek has gone back to trying to kill computers, taking back the “most punishing game” title in our benchmark suite. Only in a handful of setups can we even run Crysis 3 at its highest (Very High) settings, and the situation isn't too much better for entry-level GPUs at its lowest quality setting. In any case Crysis 1 was an excellent template for the kind of performance required to drive games for the next few years, and Crysis 3 looks to be much the same for 2013.
All of these GPUs need to run at low quality settings to get decent frame rates, but Iris Pro is actually the first Intel integrated solution that can break 30 fps here. Only AMD's desktop Trinity can claim the same. NVIDIA holds a 30% advantage, one that shrinks to 10% on the GT 640. Given the only difference between those two parts is memory bandwidth, I wonder if Crystalwell might need to run at a higher frequency here.

This is useless at anything above 1366x768 for games (and even that is questionable as I don't think you were posting minimum fps here). It will also be facing richland shortly not AMD's aging trinity. And the claims of catching a 650M...ROFL. Whatever Intel. I wouldn't touch a device today with less than 1600x900 and want to be able to output it to at least a 1080p when in house (if not higher, 22in or 24in). Discrete is here to stay clearly. I have an Dell i9300 (Geforce 6800) from ~2005 that is more potent and runs 1600x900 stuff fine, I think it has 256MB of memory. My dad has an i9200 (radeon 9700pro with 128mb I think) that this IRIS would have trouble with. Intel has a ways to go before they can claim to take out even the low-end discrete cards. You are NOT going to game on this crap and enjoy it never mind trying to use HDMI/DVI out to a higher res monitor at home. Good for perhaps the NICHE road warrior market, not much more.But hey, at least it plays quite a bit of the GOG games catalog now...LOL. Icewind Dale and Baldur's gate should run fine :)

Shimpi's guess as to what will go into the 15-inch rMBP is interesting, but I have a gut feeling that it will not be the case. Despite the huge gains that Iris Pro has over the existing HD 4000, it is still a step back from last year's GT 650M. I doubt Apple will be able to convince its customers to spend $2199 on a computer that has less graphics performance than last year's (now discounted) model. Despite its visual similarity to an Air, the rMBP still has performance as a priority, so my guess is that Apple will stick to discrete for the time-being.That being said, I think Iris Pro opens up a huge opportunity to the 15-inch rMBP lineup, mainly a lower entry model that finally undercuts the $2000 barrier. In other words, while the $2199 price point may be too high to switch entirely to iGPU, Apple might be able to pull it off at $1799. Want a 15-inch Retina Display? Here's a more affordable model with decent performance. Want a discrete GPU? You can get that with the existing $2199 price point.
As far as the 13-inch version is concerned, my guesses are rather murky. I would agree with the others that a quad-core Haswell with Iris Pro is the best-case scenario for the 13-inch model, but it might be too high an expectation for Apple engineers to live up to. I think Apple's minimum target with the 13-inch rMBP should be dual-core Haswell with Iris 5100. This way, Apple can stick to a lower TDP via dual-core, and while Iris isn't as strong as Iris Pro, its gain over HD 4000 is enough to justify the upgrade. Of course, there's always the chance that Apple has temporary exclusivity on an unannounced dual-core Haswell with Iris Pro, the same way it had exclusivity with ULV Core 2 Duo years ago with MBA, but I prefer not to make Haswell models out of thin air.

You are assuming that the next MBP will have the same chasis size. If thin is in, the dGPU-less Iris Pro is EXTREMELY attractive for heat/power considerations..More likely is the end of the thicker MBP and separate thin MBAir lines. Almost certainly, starting in two weeks we have just one line, MBP all with retina, all the thickness of MBAir. 11" up to 15"..

As far as encoding goes, why do you guys ignore cuda?http://www.extremetech.com/computing/128681-the-wr...
Extremetech's last comment:
"Avoid MediaEspresso entirely."
So the one you pick is the worst of the bunch to show GPU power....jeez. You guys clearly have a CS6 suite lic so why not run Adobe Premiere which uses Cuda and run it vs the same vid render you use in Sony's Vegas? Surely you can rip the same vid in both to find out why you'd seek a CUDA enabled app to rip with. Handbrake looks like they're working on supporting Cuda also shortly. Or heck, try FREEMAKE (yes free with CUDA). Anything besides ignoring CUDA and acting like this is what a user would get at home. If I owned an NV card (and I don't in my desktop) I'd seek cuda for everything I did that I could find. Freemake just put out another update 5/29 a few days ago.

2.5yrs ago it was equal, my guess is they've improved Cuda use by now. You've gotta love Adam and Jamie... :) Glad they branched out past just the Mythbusters show.

I have a bad suspicion one of the reasons why you won't see a desktop Haswell part with eDRAM is that it would pretty much euthanize socket 2011 on the spot.IF Intel does actually release a "K" part with it enabled, I wonder how restrictive or flexible the frequency ratios on the eDRAM will be?
Speaking of socket 2011, I wonder if/when Intel will ever refresh it from Sandy-E?

I wouldn't call myself an expert on computer hardware, but isn't it possible that Iris Pro's bottleneck at 1600x900 resolutions could be attributed to insufficient video memory? Sure, that eDRAM is a screamer as far as latency is concerned, but if the game is running on higher resolutions and utilising HD textures, that 128MB would fill up really quickly, and the chip would be forced to swap often. Better to not have to keep loading and unloading stuff in memory, right?Others note the similarity between Crystalwell and the Xbox One's 32MB Cache, but let's not forget that the Xbox One has its own video memory; Iris Pro does not, or put another way, it's only got 128 MB of it. In a time where PC games demand at least 512 MB of video RAM or more, shouldn't the bottleneck that would affect Iris Pro be obvious? 128 MB of RAM is sure as hell a lot more than 0, but if games demand at least four times as much memory, then wouldn't Iris Pro be forced to use regular RAM to compensate, still? This sounds to me like what's causing Iris Pro to choke at higher resolutions.
If I am at least right about Crystalwell, it is still very impressive that Iris Pro was able to get in reach of the GT 650M with so little memory to work with. It could also explain why Iris Pro does so much better in Crysis: Warhead, where the minimum requirements are more lenient with video memory (256 MB minimum). If I am wrong, however, somebody please correct me, and I would love to have more discussion on this matter.

Me thinks thou not know what thou talking about ;)F_A - Monday, June 3, 2013 - link
The video memory is stored in main memory being it 4GB and above...(so minspecs of crysis are clearly met)... the point is bandwidtht.The article is telling there are roughly 50GB/s when the cachè is run with 1.6 Ghz.
So ramping it up in füture makes the new Iris 5300 i suppose.

Video cards may have 512MB to 1GB of video memory for marketing purposes, but you would be hard pressed to find a single game title that makes use of more than 128.tipoo - Wednesday, January 21, 2015 - link
Uhh, what? Games can use far more than that, seeing them push past 2GB is common. But what matters is how much of that memory needs high bandwidth, and that's where 128MB of cache can be a good enough solution for most games.
