Benchmarks at overclocked speed for 3570/3700/8350?

[Makhaira]

Thinking of upgrading in the near future from my Q9550 (I've been saying this for a while!), and want to get a chip that will cope with occasional mid-level gaming, but also tear through video transcoding.

I realise that in transcoding the 8350 is on a par with the (much more expensive) 3770K at stock speeds, but I won't run any of these chips at stock!

So, on a typical overclock for each of the 3 chips, how does their performance scale in both games and multi-thread transcoding?

Thanks!

The intel chips will beat the AMD chip in games.

Transcoding will prbably be a toss up between the two depending on application.

That means you have to make a decision between the 3570k or a 3770k.

Not a big difference in games. Your decision should then be how serious are you at transcoding?

If it's serious, then get the 3770k, if it's occasional, then save your money and go 3570k.

However Haswell is round the corner, maybe wait to upgrade to that. I would, being we are so close.

Not just on par - about 10% faster. At stock from anandtech the x264 pass 2 FPS:
FX-8350@ 4.0 = 44 FPS
3570K @ 3.4 = 30.7 FPS
3770K @ 3.5 = 39.9 FPS

In well-threaded cpu-limited apps you might approximate the compute speed as going linearly with clock speed. So if we imagine they all get to 4.5 GHz and it's totally cpu limited we might expect:
FX-8350@ 4.5 = 49.5 FPS ?
3570K @ 4.5 = 40.6 FPS ?
3770K @ 4.5 = 51.3 FPS ?

Probably not be a very good approximation but gives you an idea, it would seem the 3770K has to overclock a lot to catch the 8350. This is probably partly due to the massive L2 and L3 caches in the 8350 compared to the Intel chips.
