If it has an Iris pro then the L3 size is irrelevent. The issue you will run into though is that the I5 only have 4 cores and no hyperthreading. To take full advantage you need 8 threads. Make sure for the low power setting you are putting in 5. you should probably be in the 300s
Well that sucks a bit. And I was wondering why they don't have hyperthreading, every i5 I've owned up to now has. Weird.
Still, at 300 I'm not thrilled but I'd be happy enough, that's a 4.5-5 month ROI which is about average for mining gear. It's only pulling 40W so far while mining, so that's not too shabby...
Damn not bad at all - 71w is what my i7 version is using.
