Intel "S" processors

[JumBie]

For instance, a i5-4430S is apparently exactly the same as a i5-4430 except it has its multicore frequency lowered. Is it possible to get the S processors to work at full speed? Can't I just up the frequency and then bam everything is fine?

You might be able to "play" with the multipliers on a motherboard with MultiCore Enhancement (ie, raise it to 3.2GHz under all loads), but that really defeats the object of getting an S processor in the first place.

I always just remember "S = Slow" so I don't get confused by the models.

Thing is, I can get a OEM 4430S for fairly cheap. Was considering tossing this in with a 270x.

They're multiplier locked, so no, you wouldn't be able to overclock them back to "stock" speeds.

And they'd re-underclock themselves anyway to stay under TDP.

A little undervolting through xtu would make them stay a bit higher without throttling, nah ?

i would so put a 35W core i3 and a 750 ti in a small itx case with a 120w power brick for the fun

Severe power or cooling restrictions are the only use case for S and T parts. So, this would work. OP's plan? Not really. I mean, its not like the parts are dogs so if you can get them cheaper than a regular part it might be worthwhile, but for normal desktop usage a regular part will be faster for less money (and after undervolting, a regular part may actually use less electricity because it gets to wait states faster).

4790S is rated 65W but in the AVX test it pulls 77W at the CPU level, that is 18% more than the official TDP...

So does my 4770K. Those TDP numbers do not represent actual power consumption.

TDP is the requirements for cooling. Ex a tablet can cool a SoC with about a max of 5 watt TDP. However, the SoC could draw 14 watts, TDP is just wasted electricity that is heat. How come so many people think TDP=Power comsumption..

On Haswell's, AVX "power viruses" like Prime, IBT & Linpack don't even begin to reflect real-world load power consumption either (compare Linpack to X264 encode both at 100% CPU load):-
