Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested
by Anand Lal Shimpi on June 1, 2013 10:01 AM ESTMetro: Last Light
Metro: Last Light is the latest entry in the Metro series of post-apocalyptic shooters by developer 4A Games. Like its processor, Last Light is a game that sets a high bar for visual quality, and at its highest settings an equally high bar for system requirements thanks to its advanced lighting system. This doesn’t preclude it from running on iGPUs thanks to the fact that it scales down rather well, but it does mean that we have to run at fairly low resolutions to get a playable framerate.
Metro is a pretty heavy game to begin with, but Iris Pro starts off with an extremely good showing here. In its 55W configuration, Iris Pro is only 5% slower than the GeForce GT 650M. At 47W the gap is larger at 11% however. At 1366 x 768 the difference seems less memory bandwidth related and has more to do with efficiency of the graphics hardware itself.
The comparison to mobile Trinity is a walk in the park for Iris Pro. Even a 100W desktop Trinity part is appreciably slower here.
Increasing the resolution and quality settings changes things quite a bit. The 650M pulls ahead, and now the Iris Pro 5200 basically equals the performance of the GT 640. Intel claims a very high hit rate on the L4 cache, however it could be that 50GB/s is just not enough bandwidth between the GPU and Crystalwell. The performance improvement compared to all other processor graphics solutions, regardless of TDP, is still well in favor of Iris Pro. The i7-4950HQ holds a 50% advantage over the desktop i7-4770K and is almost 2x the speed of the i7-3770K.
Comparing mobile to mobile, Iris Pro delivers over 2x the frame rate of Trinity.

As soon as intel CPUs have video performance that exceeds NVidia and AMD flagship video cards I'll get excited. Until then I think of them as something to be disabled on workstations and to be tolerated on laptops that don't have better GPUs on board.MySchizoBuddy - Monday, June 3, 2013 - link
So Intel just took the OpenCL crown. Never thought this day would come.prophet001 - Monday, June 3, 2013 - link
I have no idea whether or not any of this article is factually accurate.However, the first page was a treat to read. Very well written.

Great success by Intel.4600 is near GT630 and HD4650 (much better than 6450 which sells for $15 at newegg)
5200 is better than GT640 and HD 6670 (currently sells like $50 at newegg)
Intel's intergrated used to be worthless comparing with discret cards. It slowly catches up during the past 3 years, and now 5200 is beating a $50 card. Can't wait for next year!
Hopefully this will finally push AMD and Nvidia to come up with meaningful upgrade to their low level product lines.

A quick check for my own sanity:Did you configure the A10-5800K with 4 sticks of RAM in bank+channel interleave mode, or did you leave it memory bandwidth starved with 2 sticks or locked in bank interleave mode?
The numbers look about right for 2 sticks, and if that is the case, it would leave Trinity at about 60% of its actual graphics performance.
I find it hard to believe that the 5800K is about a quarter the performace per watt of the 4950HQ in graphics, even with the massive, server-crushing cache.

is this new cpu faster than the 4770k? it sure cost more?zodiacfml - Monday, June 3, 2013 - link
impressive but one has to take advantage of the compute/quick sync performance to justify the increase in price over the HD 4600ickibar1234 - Tuesday, June 4, 2013 - link
Well, my Asus G50VT laptop is officially obsolete! A Nvidia 512MB GDDR3 9800gs is completely pwned by this integrated GPU, and, the CPU is about 50-65% faster clock for clock to the last generation Core 2 Duo Penryn chips. Sure, my X9100 can overclock stably to 3.5GHZ but this one can get close even if all cores are fully taxed.Can't wait to see what the Broadwell die shrink brings, maybe a 6-core with Iris or a higher clocked 4-core?
I too see that dual core versions of mobile Haswell with this integrated GPU would be beneficial. Could go into small 4.5 pounds laptops.
AMD.....WTH are you going to do.

AMD has to create a Crystalwell of their own. I never thought Intel could beat them to it since their integrated GPUs always has needed bandwidth ever since.Spunjji - Tuesday, June 4, 2013 - link
They also need to find a way past their manufacturing process disadvantage, which may not be possible at all. We're comparing 22nm Apples to 32/28nm Pears here; it's a relevant comparison because those are the realities of the marketplace, but it's worth bearing in mind when comparing architecture efficiencies.
