Generally speaking, lowering / restricting the frequencies can lower the maximum TDP of any CPUs. Doing so can also mean you might also be able to lower the voltage to the CPU which in turns means lower power consumption and lower TDP. The motherboard's BIOS can be used to adjust the voltage if it provides those options.
Not sure what the specific difference is between the HD 4400 and the HD 4600 other than the frequency. However, I suspect the HD 4400 has fewer shaders which is a measure of graphics performance. More shader units generally means more potential performance, but also higher TDP.
Thanks for an answer I've been waiting days lol
, btw if a processor can't overclock, it can still underclock and undervoltage, right? All Micro ATX motherboarda can undervolt? This one can?: cant find one -_- they are all US only (micro ATX)
The haswell I3s might be different but my Ivy I3 I put in my parent's comptuter I can't change the multi so you couldn't underclock it if you wanted to. So I think your best bet is to either deal with the higher TDP, or get teh T model that is OEM
This one isn't Ivy (Ivy Bridge) but Haswell (4th gen), thanks for taking interest though
