I was looking at the Coffee Lake CPU lineup on Wikipedia
https://en.wikipedia.org/wiki/Coffee_Lake
and I notice there's a CPU like the i5 8400 with 6c,6t that can turbo up to 4.0 on 1 core and 3.8 on all cores.
then I see a T series processor i7 8700T with 6c,12t that can also turbo up to 4.0 on one core and 3.8 on all 6. And it has faster clocked iGPU ontop of that.
Does advertised TDP not count for when a CPU is turbo-ing? Or are the T series CPUs binned for higher efficiency?
Only reason I ask is for potential future build. A CPU like the i5 8400 is 100 USD cheaper, but when I take into account the death of Moores law and the fact that I'm still using my i5 3450 6 years later without much issue (a CPU that the i5 8400 / i7 8700T would completely destroy) I have to assume that this next system could be in service for well over a decade and that long-term power consumption may play more role in CPU choice than ever before.
And then there's underclocking, but I don't know how to do that or if it's even possible on locked CPUs or if it would achieve the same performance/watt as one of these T series models.
Another consideration is Ryzen APU. Vega 11 absolutaly crushes UHD 630, but 4 cores is so boring in 2018. I have to wonder if Zen 2 APUs on 7nm will see any 6 core APU parts.
