FX51 vs. Athlon64 +3200
What is the difference between the AMD FX51 and the Athlon64 +3200 ? I know the FX is several hundred dollars more expensive but, I don't know why. Please explain it so a dunce like me can understand.
The fx-51 is 2.2ghz and uses duel channel ram(giving it twice the bandwidth);but also can use only ecc ram(which is more stable,but also a little slower than its clocked speed;because of the greater bandwidth it should perform much better under an actual 64 bit OS.
The Athlon64 uses single channel ram,supports only 1 gig of the fastest 400ddr ram-it's its inferior bandwidth and limited ability to support more ram which mainly make it inferior.It is mainly locked(limiting overclocking),unlike the fx-51 which is unlocked and can be overclocked.The mobos for the amd64 are also more numerous and cheper than those for the fx-51.
Really,there's no good cpu for a value built right now,by value I mean a system that will be great for a year,good for two more and ok with overclocking for two more.The amd64 does not have a lifespan of more than half that,the fx-51 will really be showing its age when real 64 bit systems using ddr2 and pci express come out and the intel cpu are not 64 bit capable;but the fx-51 is the best out there if you can afford such an expensive gaming-workstation and are willing to build again in a year.With both of the 64 bit cpu system you'll have to upgrade the GPU to a 64 bit system.I would say wait a year to a year and a half for a value build which will have a 64 bit OS, GPU/video card and ddr2 or at least wait 6 moths for the new amd socket 939 supporting non-ecc duelk channel ram or intels yamhil/prescott.
AMD64 dont bother really while the AMD FX51 is if you got the money. May just wanna wait for the next socket release, other wise get yourself a good Barton or t-bred chip and have some fun OCing the shizzel out of it.
