Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested
by Anand Lal Shimpi on June 1, 2013 10:01 AM ESTPricing
Intel's launch lineup with Haswell is pretty spartan, but we do have enough information to get a general idea of what Crystalwell will cost as an addition.
| Peak Theoretical GPU Performance | |||||||||||||||||||
| CPU Cores/Threads | CPU Clock (Base/4C/2C/1C Turbo) | Graphics | GPU Clock (Base/Max Turbo) | TDP | Price | ||||||||||||||
| Intel Core i7-4950HQ | 4/8 | 2.4/3.4/3.5/3.6GHz | Intel Iris Pro 5200 | 200/1300MHz | 47W | $657 | |||||||||||||
| Intel Core i7-4850HQ | 4/8 | 2.3/3.3/3.4/3.5GHz | Intel Iris Pro 5200 | 200/1300MHz | 47W | $468 | |||||||||||||
| Intel Core i7-4800MQ | 4/8 | 2.7/3.5/3.6/3.7GHz | Intel HD 4600 | 400/1300MHz | 47W | $378 | |||||||||||||
The i7-4950HQ and i7-4850HQ are the only two Iris Pro 5200 parts launching today. A slower 2GHz i7-4750HQ will follow sometime in Q3. CPU clocks are a bit lower when you go to GT3, likely to preserve yield. Compared to the i7-4800MQ the 4850HQ carries a $90 premium. That $90 gives you twice the number of graphics EUs as well as the 128MB of eDRAM. Both adders are likely similar in terms of die area, putting the value of both at $45 a piece. Now you are giving up a bit on the CPU frequency side, so the actual cost could be closer to $50 or so for each. Either way, Iris Pro 5200 doesn't come cheap - especially compared to Intel's HD 4600.
From talking to OEMs, NVIDIA seems to offer better performance at equivalent pricing with their GT 740M/750M solutions, which is why many PC OEMs have decided to go that route for their Haswell launch platforms. What Intel hopes however is that the power savings by going to a single 47W part will win over OEMs in the long run, after all, we are talking about notebooks here.

"What Intel hopes however is that the power savings by going to a single 47W part will win over OEMs in the long run, after all, we are talking about notebooks here."This plus simpler board designs and fewer voltage regulators and less space used.
And I agree, I want this in a K-SKU.

And doesn't MacOS support Optimus?RE: "In our 15-inch MacBook Pro with Retina Display review we found that simply having the discrete GPU enabled could reduce web browsing battery life by ~25%."

Those are strong words in the end, but i agree Intel should make a K-series CPU with Crystalwell. What comes to mind is they may be doing that for Broadwell.The Iris Pro solution with eDRAM looks like a nice fit for what i want in my notebook upgrade coming this fall. I've been getting by on a Core2Duo laptop, and didn't go for Ivy Bridge because there were no good models with a 1920x1200 or 1920x1080 display without dedicated graphics. For a system that will not be used for gaming at all, but needs resolution for productivity, it wasn't worth it. I hope this will change with Haswell, and that i will be able to get a 15" laptop with >= 1200p without dedicated graphics. 4950HQ or 4850HQ seems like an ideal fit. I don't mind spending $1500-2000 for a high quality laptop :)

ANAND!!You got the FLOPs rating wrong on the Sandy Bridge parts. They are at 1/2 of Ivy Bridge.
1350MHz with 12 EUs and 8 FLOPs/EU will result in 129.6GFlops. While its true in very limited scenarios Sandy Bridge's iGPU can co-issue, its small enough to be non-existent. That is why a 6EU HD 2500 comes close to 12EU HD 3000.

If they use only the HD4600 and Iris Pro that'd probably be better. As long as it's clearly labeled on laptops. HD 4600 Pro (don't expect to do any video work on this) Iris Pro (it's passable in a pinch).But I don't think that's what's going to happen. Iris Pro could be great for Ultrabooks; I don't really see any use outside of that though. A low end GT740M is still a better option in any laptop that has the thermal room for it. Considering you can put those in 14" or larger ultrabooks I still think Intel's graphics aren't serious. Then you consider the lack of Compute, PhysX, Driver optimization, game specific tuning...
Good to see a hefty performance improvement. Still not good enough though. Also pretty upsetting to see how many graphics SKU's they've released. OEM'S are gonna screw people who don't know just to get the price down.

The SKU price is 500 DOLLARS!!!! They're charging you 200 bucks for a pretty shitty GPU. Intel's greed is so disgusting it over rides the engineering prowess of their employees. Truly disgusting Intel; to charge that much for that level of performance. AMD we need you!!!!xdesire - Tuesday, June 4, 2013 - link
May i ask a noob question? Question: Do we have no i5s, i7s WITHOUT on board graphics any more? As a gamer i'd prefer to have a CPU + discrete GPU in my gaming machine and i don't like to have extra stuff stuck on the CPU, lying there consuming power and having no use (for my part) whatsoever. No ivy bridge or haswell i5s, i7s without iGPU or whatever you call it?flyingpants1 - Friday, June 7, 2013 - link
They don't consume power while they're not in use.Hrel - Tuesday, June 4, 2013 - link
WHY THE HELL ARE THOSE SO EXPENSIVE!!!!! Holy SHIT! 500 dollars for a 4850HQ? They're charging you 200 dollars for a shitty GPU with no dedicated RAM at all! Just a cache! WTFF!!!Intel's greed is truly disgusting... even in the face of their engineering prowess.

What I don't understand is why Intel didn't do a "next-gen console like processor". Like takeing the 4770R and doubling the GPU or een quadrupling, wasn't there space? The thermal headroom must have been there as we are used to CPUs with as high as 130W TDP. Anyhow, combining that with awesome drivers for Linux would have been a real competition to AMD/PS4/XONE for Valve/Steam. A complete system under 150w capable of awesome 1080p60 gaming.So now I am looking for the best performing GPU under 75W, ie no external power. Which is it, still the Radeon HD7750?
