Oh, yes. Thanks for the correction.

I thought only Pro SKUs get EDRAM but turns out I was wrong.

I didn't know 540 had eDRAM! That's awesome. Their naming sceme is very confusing.

For Skylake, yes. For Haswell and Broadwell, no. A small "e" on the graphics generation denotes eDRAM. Iris 5100 (Haswell) and Iris 6100 (Broadwell) were GT3, no eDRAM. Iris Pro 5200 (Haswell) and Iris Pro 6200 (Broadwell) were GT3e with eDRAM.

For Skylake they switched it up so that Iris 540 and Iris 550 are both GT3e, and Iris Pro 580 is GT4e. All with eDRAM. My comment above is incorrect, Iris 550 is not the "pro" version, Iris Pro 580 is.
