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.

They are completely different systems making power consumption values irrelevant.codedivine - Saturday, June 1, 2013 - link
Hi folks. Can you post the OpenCL extensions supported? You can use something like "GPU Caps viewer" from Geeks3d.tipoo - Saturday, June 1, 2013 - link
Interesting that the compute is punches above it's game performance weight. I wonder if they could put more EUs in a chip, maybe a larger eDRAM, and put it on a board as a compute card.lmcd - Saturday, June 1, 2013 - link
They already have a compute card called Xeon Phi if I remember correctly.Klimax - Sunday, June 2, 2013 - link

I'm aware, but the Xeon Phi requires completely different programming than a GPU like this which can just use OpenCL.Soul_Master - Saturday, June 1, 2013 - link
What's your point for comparing desktop GPU with middle-range mobile GPU? CPU on both devices are not equal.Soul_Master - Saturday, June 1, 2013 - link
Sorry. I misunderstood about i7 4950HQ process, a high-end quad-core processor for laptops.Ryan Smith - Sunday, June 2, 2013 - link
It's what we had available. We wanted to test a DDR3 version of GK107, and that's what was on-hand.tipoo - Saturday, June 1, 2013 - link
Hmm, so it's heavily hinted at that the next rMBP will ditch discreet graphics. The 5200 is good, but that would still be a regression in performance. Not the first time Apple would have done that, there was the Radeon cut out of the Mini, the 320M to the 3000, even the bottom rung of the newest iMac with the 640m. I wonder if it would at least be cheaper to make up for it.
