How many ROPs/TMUs in Iris Pro, exactly?

[tipoo]

I have GPU-Z open right now on Windows on my Haswell rMBP, and it's listing 8 ROPs and 32 TMUs. But on sites online, it's listed at 2 and 8, among some other variances like 4 and 8. Which is it exactly? If the following site is true, it would seem surprising that it can even come close to it's competition with just 2 ROPs, even clocked high?

(at second glance at the above, lol16gflops, lets call that site baloney. The below lists a more reasonable 4 and 8, but still seems low for the performance range if you look at what it's near like the 640)

It is 8 and 32.

It is 8 and 32.

That would make the most sense to me with its performance range. Source though? Havn't yet found a site reflecting what GPU-Z tells me.

I have another question related to this GPU, may as well plop it in here rather than make another thread. So many moons ago, Anandtech tested the state of OSX graphics performance and found it was so far behind Windows it was like getting the same card from a generation ago. This was when Snow Leopard came out however, and it was with Radeons and Geforces.





Now that I have a Iris Pro 5200 in my Macbook Pro, I'm wondering if things have changed. For cross platform games, which it would run better on. I know with the HD4000, the Intel driver got some extra lovin from Apple just to try to make up for switching away from the 320M from Nvidia. Has that continued on to the 5200, and in which case, which OS performs better with this specific GPU from Intel? Anyone seen any tests of this?

I think I was wrong.

Those are the only values that make sense when comparing to the theoretical pixel and texturing performance.

~10.4 Gp/s / 1300 mhz = 8 ROP
~20.8 Gt/s / 1300 mhz = 16 TMU

This may be wrong for the TMU's.

DX will likely be the fastest. Windows has pretty much always done better with DX.
