Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested

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.

The performance isn't earth-shattering, but if Intel manages to put out good open-source Linux drivers for Iris Pro, I can't help but feel like this would be a great chip for that; it isn't like you'll be playing Crysis in Ubuntu anytime soon. I kind of want that CRB (or something like it), actually.tviceman - Saturday, June 1, 2013 - link
I'll bet notebooks with mid-range quad core CPU's and gt 750m discrete graphics will be cheaper than notebooks with Iris Pro enabled iGPU graphics as well. The only benefit would be a slightly slimmer chassis and battery life. Anyone who still wants to game on a notebook is noticeably better off with a mid-range discrete GPU over this.esterhasz - Saturday, June 1, 2013 - link
On page four, the ominous launch partner is not "keen" rather than "key", I guess. I'd be very keen on having that rMBP 13" with IP5200, though.Ryan Smith - Saturday, June 1, 2013 - link
Noted and fixed. Thank you.tipoo - Saturday, June 1, 2013 - link
I'm very much in that boat too, a quad core 13" rMBP with Iris Pro would put it over the top.MattVincent - Wednesday, June 12, 2013 - link
totally agree. I wonder if apple will actually put a quad core in the 13" though. I bet they would rather sell more 15" rmbp'sjeffkibuule - Saturday, June 1, 2013 - link
Would a 47W chip be able to fit into a normal 13" Ultrabook-like chassis like the 13" MacBook Pro with Retina Display? Only an extra 12W TDP to deal with.esterhasz - Saturday, June 1, 2013 - link
This would be awesome and we have to remember that the 47W TDP includes voltage regulation moving off the MB, so the gap is maybe only 8W. The 47 TDP also refers to both CPU and GPU running at full speed, which is an extremely rare scenario - in gaming, the CPU load will probably hover at 50% only.In any case, if the tested model goes into a rMBP 13" I'm going to buy it before Tim Cook has left the stage.

Thinking to buy a Ivybridge Mac Book Pro for my wife, I guess she will have wait a little longer for this baby. I wish they could fit in a Mac Book Air.jeffkibuule - Saturday, June 1, 2013 - link
Look at the price of those chips though, you're going to be dropping at least $2000 on such a laptop when the CPU alone is $478.
