How dows intel's graphics architehture really compare against competition(nvidia/amd)

[ultimatebob]

The Intel Iris Pro graphics are actually pretty good. It's about on par with the NVidia 500 mobile series, which isn't bad for integrated graphics.

 

[Enigmoid]

The Iris Pro IGP section is around 160MM2 to 165MM2 in size plus 80MM2 of L4 cache.

The Kaveri IGP section is around 120MM2.

Kaveri is 245 mm^2 * 0.47 = 115 mm^2

Iris pro is 177 mm^2 * 0.31 = 55 mm^2 * 2 slices = 110 mm^2 (likely less because the second slice doesn't duplicated some elements like the video display controller).

These are only rough estimates but iris pro is on a slightly denser process as well.
