How does 8.6ghz on liquid helium single core have ANY relevance to mainstream computer applications? What they're saying is that with a mainstream air CPU cooler, you'll have better performance gains with Ivy Bridge (or Sandy Bridge). It just runs cooler. And consumes like.. literally half as much power.

Power consumption 195 watts for FX-8350 vs 101 watts for i5-3570K. Ivy bridge uses literally 52% as much power as the FX-8350 system (this being with a lot of shared components as well, meaning the gap between processors is possibly more significant.

The other problem is that the FX-8350 barely beats the 3570K in multithreaded stuff. Usually 10-15% at most I believe, and sometimes a range of -5 to 15% (It does have one ~35% win). Whereas for single threaded performance, Intel's advantage is anywhere from 0% to 50% (Cinebench, gaming, whatever you want to pick). Gaming here, and you can go back a page for photoshop and other things.

Again, all while consuming like twice as much power as the i5 >.>

So: How does 8.6ghz liquid helium cooled have any relevance to mainstream computing applications, and how do you justify a 15% at most (normally) gain in multithreaded applications, while taking a 50% hit in single-threaded stuff AND consuming twice as much power? Sure, the OP is multi-threaded, but not everything he does will be multi-threaded as efficiently as all benchmarks, and not everything he does would be multithreaded, period. I mean yes, it's better for multithreaded, but not really by much, and if even half of what OP does is single threaded or not efficiently multithreaded, wouldn't Intel be better? (Granted, if the OP is really almost all really multithreaded, 8350 is gonna be better, but there's still power to consider).
