So around 4TFLOPS, but "not cutting edge tech"...that would mean 28nm.
M9 M395X is 2048:128:32 mobile 28nm GPU pulling 3.7TFLOPS with TDP of 125W (desktop version is 380X with ~4TFLOPS and 190W) and I don't think AMD can go much lower with TDP on 28nm for similar specs.
Somehow I find this rumour hard to believe, if it's around 4TFLOPS it's more likely to be 14nm, or it's not anywhere near 4TLFOPS.
