waiting for the review from the xpert.is it worth to choose amd fx over i5 2400.
If you overclock, the FX is certainly better than the 2400 in all circumstances. You're better off comparing with the 2500K and 2600K processors.
Got to play with a review sample. Not mine. I'm not NDAed.
The figures above posed by w00key do seem legit, but they're worst cases. In most games, BD trades places with a 2500K, in my own Fallout New Vegas testing, it beat my Phenom II X4 (3.7 GHz) by around 20%. The 2500K beats my Phenom II by the same 20%.
It's hilariously overclockable. Jury-rigging the biggest heatsink I could find, a ~7 year old Coolermaster Hyper6+ (which doesn't fit AM2/3) hacked into a pretty cheap Gigabyte GA990XA-UD3, I got 4.85 GHz out of it. At that kind of clock, the 2500K was looking for its parents with tears in its eyes, losing out on single threaded benchmarks by 10% and multithreads.... well, it wasn't really funny anymore. I'll share with you this:
Code:
CODE

BD 4.85 12:33
2500K 3.8 18:56
PII X4 3.7 21:30

BD 4.85 8:40
2500K 3.8 11:01
PII X4 3.7 15:15
* I'd like to have overclocked the 2500K more, but I was limited to a pretty shitty motherboard which looked to be an Asus but had no identifying marks and Intel's stock cooler.
** x264 June 2011 used. VirtualDub passing through AVISynth to the CLI x264 binary. VD was using a MoComp deinterlace filter which scales linearly to, according to the author, at least 24 cores.
It's competitive. For some workloads, you're going to want Intel. For others, AMD at last can out-perform Intel. I didn't have a 2600K to test, but if I had, I'd imagine BD would have beat it.
Of course these are all overclocked figures. Blame contractual loopholes.
Edit: Oh yeah, not allowed to say which model BD I was playing with. Also, to address the below, I couldn't boot the 2500K box with a multiplier any higher than 38. Even with scary voltages. I blame the Hybrid-EFI BIOS or some quirk of the board.
So an 8-core FX CPU is 33% faster than a 2500K with a 27% clockspeed advantage.
