Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Tested
by Anand Lal Shimpi on June 1, 2013 10:01 AM ESTSynthetics
Our synthetic benchmarks can sometimes tell us a lot about what an architecture is capable of. In this case, we do have some unanswered questions about why Intel falls short of the GT 650M in some cases but not in others. We'll turn to 3DMark Vantage first to stress ROP and texel rates.
Iris Pro doesn't appear to have a ROP problem, at least not in 3DMark Vantage. NVIDIA can output more pixels than Iris Pro though, so it's entirely possible that we're just not seeing any problems because we're looking at a synthetic test. Comparing the HD 4600 to the Iris Pro 5200 we see near perfect scaling in pixel throughput. Remember the ROP hardware is located in slice common, which is doubled when going from GT2 to GT3. Here we see a near doubling of pixel fillrate as a result.
Moving on, we have our 3DMark Vantage texture fillrate test, which does for texels and texture mapping units what the previous test does for ROPs.
Now this is quite interesting. NVIDIA has a 50% advantage in texturing performance, that's actually higher than what the raw numbers would indicate. It's entirely possible that this is part of what we're seeing manifest itself in some of the game benchmarks.
Finally we’ll take a quick look at tessellation performance with TessMark.
Iris Pro doesn't appear to have a geometry problem. Tessellation performance is very good.

Looking at the prices, this will raise the price or Lower the margins of the 13" Retina Macbook Pro by about $150 each.mschira - Sunday, June 2, 2013 - link
Yea laptops benefit most - good for them.But what about the workstation?
So intel stopped being a CPU company and turned into a mediocre GPU company? (can even beat last years GT650M)
I would applaude the rise in GPU performance if they had not completely forgotten the CPU.

You're exactly right.13" ultrabook buyers who need it the most get little to nothing out of this.
And desktop users don't need or want GT3e and it uses system RAM. Better off buying a graphics card instead of upgrading to Haswell on desktops.

While I agree this misses "where it would benefit most", I disagree on just *where* that is.I guess Intel agrees with Microsofts implicit decision that media center is dead. Real-time HQ quicksync would be perfect to transcode anything extenders couldn't handle, and would also make the scanning for and skipping of commercials incredibly efficient.

Core i5…4350U…Iris 5000…15W…1.5 GHzCore i7…4550U…Iris 5000…15W…1.5 GHz
Core i7…4650U…Iris 5000…15W…1.7 GHz
These should work. The 4650U is available in the Sony Duo 13 as we speak, though at a hefty price tag of $1,969

The last 13" looks like they were prepping it for a fusion drive then changed their mind leaving extra space in the enclosure. I think it is due for an internal redesign that could allow for a higher wattage processor.I think the big deal is the OpenCL performance paired with ECC memory for the GPU. The Nvidia discrete processor uses non-ECC GDDR. This will be a big deal for users of Adobe products. Among other things, this solves the issue of using the Adobe mercury engine with non-ECC memory and the resulting single byte errors in the output. The errors are not a big deal for games, but may not be ideal for rendering professional output and scientific applications. This is basically a mobile AMD FireGL or Nvidia Quadro card. Now we just need OpenCL support for the currently CUDA-based mercury engines in After Effects and Premiere. I have a feeling that is coming or Adobe will also lose Mercury Engine compatibility with the new Mac Pro.

Impressive iGPU performance, but I knew Intel was absolutely full of sh!t when claiming equal to or better than GT 650m performance. Not really even close, typically behind by 30-50% across the board.Krysto - Saturday, June 1, 2013 - link
When isn't Intel full of shit? Always take what the improvements they claim and cut it in half, and you'll be a lot closer to reality.xtc-604 - Saturday, June 8, 2013 - link
Lol...you think that's bad? Look at Apple's claims. "over 200 new improvements in Mountain Lion"piroroadkill - Saturday, June 1, 2013 - link
