There is a slightly higher clockspeed for a FX-57.
However, any of todays processor easily is better than a FX-57.
Not in games. Only 1 or 2 games have been patched for dual core and while in these the FX-60 or FX-62 should win all other games the FX-57 beats them hands down.
Super Pi must use both cores for if it didn't the the FX-57 would kill the FX-60 in tests. The FX-57 being clocked 200Mhz higher than the FX-60 gives it the advantage in all single core games and the single core FX-57 can easly outclock the dual core FX's and maybe a threat to even the conroe in games.
The single core FX would be a threat because its cheaper to make being it has half the structure of dual cores. Both the price and performance could cause Intel real headaches and Intel would be atleast 4 months making a single core version of their core 2 duo.
The current Core 2 duo's couldn't beat in single core a single core 65nm FX clocked to 3.6 or 3.8Ghz. If OCers can hit 3.8 at the 90nm with the single core FX's then AMD could mass produce them at 3.6 or 3.8Ghz in 65nm.
Why would AMD go back to single core is to slow Core 2 duo's sales until K8L come would be the best reason. This would Force Intel to either up their Ghz which would add alot of cost to their CPU's or come with a single core version themselves.
Tell me what enthusiast in their right mind is going to buy a single core processor at this stage? how many times in the last 3 months have you heard about an FX-57 being praised for gaming performance and recommended as a worthy upgrade??
Single core world is being phased out and the FX-62 is 2xFX-57, if AMD even tries to promote a single core gaming machine, intel will tear them to shreds in marketing, and they wouldnt have to lie.
Oh! and btw intel is bringing out single core Conroe cpus next year "Conroe-L"
Any enthusiast that wants the best gaming CPU. If its less than $700 and beats the x6800 at 2.93Ghz, which a 3.8Ghz single core FX could in games, and saves me the cost of a new mobo and memory I would buy it for my son.
Praised no but only because AMD isn't promoting the FX-57 anymore. Benchmarks shows FX-55 2.6Ghz in games are as fast as the FX-60 at 2.6Ghz. The FX-62 2.8Ghz isnt as fast as the FX-57 2.8Ghz in games because its on the slower AM2 mobo. Only the future FX-62 2.8Ghz on the 939 or the FX-64 3.0Ghz on AM2 will perform equal or more than the FX-57 2.8Ghz in games.
Oh! that single core 2 duo would be up again the K8L because Intel would atleast take 4 months to finalize the new design. AMD could come with the single core FX, old design at the 65nm process, at 3.6 to 3.8Ghz next month just in time to destroy the Core 2 duo in games.
AMD could do this and It would work if they choice to as the cheaper price would off set the future performance of games coded for dual core CPU's. Could 2 FX single cores at 3.8Ghz on the 4X4 beat the X6800? I would have to say no as added over head would limit 2 CPU's to maybe 1.6% gain in dual core programs.
I plan on buying the E6600 for myself to replace my old Celeron 1.8Ghz because, I mostly do programming and document writing on my PC, in none gamming software which a dual core is unmatched.
