Whats the difference between thse two procs? Is it the architecture and amount of instructions, etc. Also whats the real world performance difference between these two?
Thanks.
Thanks.

Difference between A64 3200, S754 and S939?

The numbers refers to the amount of pins on each chip that go into each respective socket (socket 939 and socket 754). 939 chips have their own inbuilt memory controllers which enables proper dual channel. You'll have literally double the data bandwidth with a 939. 754's rely on an older style Northbridge to talk to the RAM and the AGP which slows everything down. Go with 939.
Cheers for that mate.

Um, no. Both chip designs have onboard memory controllers, the only difference is that the 939 controller is dual channel. 939 is faster, but a well-setup 754 is also very quick indeed.
Ok, cheers for that as well

A socket 754 3200+ will be a tad faster. Although if buying new, you should go 939 to futureproof yourself.
3200+ are 2.2ghz, 512k cache, Single Channel.
3200+ (939) are 2.0ghz, 512k cache, Dual Channel.
The Dual channel has a similar performance advantage to about 100-150mhz of extra core speed.
The next socket AM2, which will upgrade to DDR2 memory is said to also only get a similar 5% advantage over 939.
I've got a Socket 754 3200+ (so maybe i'm biased), got mine permanently clocked at 2.42 ghz with no problems (Not tried any faster). At that speed its pretty much exactly the same as my housemates 3700+ with Dual Channel memory and 1mb Cache.

If you are buying new then i would wait for a couple of months and go with AM2 as that will be the new AMD socket and there will not be many, if any at all, new skt 939 cpu's being released.
There's absolutely nothing wrong with 754 though as you can see in my siggy.
