For the Intel parts there's a lot more reading between the lines required -- seems to be consensus that the HD 4600 has 2 ROPs but no indication how wide they are. The EUs seem to be 4-wide ALU sets and various slides talk about "hashes" or "quads" of pixels, which argues for 4 pixel wide ROPs (8 total). The raw fill performance seems to support that as well.
To add to the complication, the pixel processing blocks (we call them DB/CB for depth/colour buffer) often include more units for Z & stencil ops than for colour operations, the idea being that a lot of "potential pixels" don't get drawn because they are obscured by already-drawn content (reflected in the Z buffer). The AMD parts typically support 4x the number of Z ops as colour ops, not sure about Intel. The implication of this is that you have to be careful which synthetic benchmarks you look at.
