So how much better IS 2600k?

post #1 of 5
Thread Starter 
According to the pre-launch PassMark numbers, Sandy Bridge was supposed to be 33% more powerful than i7-xxx per clock.

But current numbers are disappointing. Some reviews even claim a <10% difference.

So, what IS the difference, and for someone who can use the extra two cores, what is more fallacious - getting a Quad-core or getting a year old architecture (980x)?

It really depends on what you are doing. If you play games / general tasks even the 2500K is over kill. The 2600K is great if you run many multithreaded programs. The 980X only makes sense if you do rendering / intensive multithreaded work for a living.

The 2600K is maybe only ~10% faster clock for clock, but it can overclock a lot more.

Sandy Bridge is supposed to be the replacement for 1156, in which case that figure is totally correct. 2600k is about on par with 980x

sandy bridge is 32nm it has a smaller die hence why you can get 5ghz overclock on these things . Other than that i dont know the difference ? i think thats it really.

So it's AT BEST 25% faster than an i7-920.

The 980x is 50%. And it's getting even better results in benchmarks.

What's going on?
