Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested
by Anand Lal Shimpi on June 1, 2013 10:01 AM ESTQuick Sync Performance
The 128MB eDRAM has a substantial impact on QuickSync performance. At a much lower TDP/clock speed, the i7-4950HQ is able to pretty much equal the performance of the i7-4770K. Running Haswell's new better quality transcode mode, the 4950HQ is actually 30% faster than the fastest desktop Haswell. This is just one of many reasons that we need Crystalwell on a K-series socketed desktop part.
CPU Performance
I spent most of the week wrestling with Iris Pro and gaming comparisons, but I did get a chance to run some comparison numbers between the i7-4950HQ CRB and the 15-inch MacBook Pro with Retina Display running Windows 8 in Boot Camp. In this case the 15-inch rMBP was running a 2.6GHz Core i7-3720QM with 3.6GHz max turbo. Other than the base clock (the i7-4950HQ features a 2.4GHz base clock), the two parts are very comparable as they have the same max turbo frequencies. I paid attention to turbo speeds while running all of the benchmarks and for the most part found the two systems were running at the same frequencies, for the same duration.
To put the results in perspective I threw in i7-3770K vs. i7-4770K results. The theory is that whatever gains the 4770K shows over the 3770K should be mirrored in the i7-4950HQ vs. i7-3720QM comparison. Any situations where the 4950HQ exceeds the 4770K's margin of victory over Ivy Bridge are likely due to the large 128MB L4 cache.

I didn't have a ton of time to go hunting for performance gains, but a couple of these numbers looked promising. Intel claims that with the right workload, you could see huge double digit gains. After I get back from Computex I plan on poking around a bit more to see if I can find exactly what those workloads might be.

I was under the impression that Richland has been selling on newegg as per a comment on an earlier article..I was also wondering since you had done a review on Richland from MSI notebook review i was wondering if you would do a similar comparison..

It would be appreciated just placing all the possible matches on the table and a paragraph with selection criteria for the review making the choices dispelling opinion of missing any models

Why no real power measurements? If it's so important to iris Pro, real world power numbers will be more useful than just listing TDP of the partsshinkueagle - Sunday, June 2, 2013 - link
The GIANT has awoken! Performance-wise, its amazing! Destroys Trinity! Price-wise.... Well, the area needs some work...trip1ex - Sunday, June 2, 2013 - link
Yes really disappointed there is no socketed cpu solution that have the best igpu config.But I suppose I already have Ivy Bridge i5 for my WMC pc and it is good enough. Still be a nice cheap way to build a secondary small desktop that could also do some light gaming.

Curious why Intel just doesn't go straight for the jugular and release a discrete GPU part on their 22nm process. NVidia/AMD is stuck at 28mm because of their foundries, and it appears Intel's GPU architecture is feature complete and therefore competitive with the discrete parts if they scaled up everything by 4x or 5x.NVidia & AMD should be worried about their core high-profit-margins business!

The photo you have on page 4 showing the 2 separate die is strange. The haswell die should not be square. Other photos I have seen show the expected (extremely rectangular) haswell die and a tiny ram chip. I would expect a haswell based chip with double the cpu (8 real cores), and no gpu eventually; this would be almost square. Do you know why your chip does not match other multi-chip module photos online?jamescox - Tuesday, June 4, 2013 - link
I guess the other photos are haswell plus an integrated chipset in the same module. The photo of the two die is still strange, as neither of these look like a haswell die.IntelUser2000 - Tuesday, June 4, 2013 - link
That's because that's the picture for GT3e Iris Pro 5200 graphics. The bigger square die is the Haswell CPU+GT3 GPU, while the smaller one is the on-package DRAM.The dual core with on-package chipset is even longer than the regular Haswell.

Yes it should, you're thinking of the ultrabook chips with a controller to the side, not eDRAM. Those ones are rectangular. Look at a haswell MBP 15" teardown to verify.
