AMD 754 3200+ vs 939 3200+

[ty1er]

I am wondering if the two proform equally since there is a 200mhz differance between the two.

example:
3200 939 runs at 2.0ghz
vs
3200 754 runs at 2.2ghz

Or

example:
3000+ 939 (1.8)
vs
3000+ 745 (2.0)

im assuming that the dual channel on of the 939 makes up for the lack of the 200mhz. but i would like to see eveidence on it.

I am in the market of picking up a new AMD64 system but i still havent made up my mind on which skt to go for.
It seems like alot of people stress the fact to go with the 939 for the "future upgradablity" which all in all makes sence, but when i do my upgrades i usually upgrade mobo, ram, cpu at the same time.

i am just curious i have been seaching around and havent been able to dig up any data comparing the two sockets at the same PR rating.

take speed obviously

It is very unlikely that clockspeed is bet by dual-channel RAM (or bigger cache for that matter).

From what I have seen only the current Half-Life 2 tests actually profit from dual-channel memory enough to make good for 10% clockspeed (and only UT2004 seems to make good enough use of 1024 KB cache).

AMD tries to push the 939 socket and that is why they give you an equally fast CPU in the 754 socket cheaper. The same thing can be observed with other AMD price levels, the best price/performance is always the higher clockspeed you get with the 52 LB cache and the 754 socket.

That brings me to a question. The only processors I've seen equipped for dual channel are the 3500+ and above chips. Everything rated below seems only good for single channel even on socket 939. Is that right or are all s939 chips equipped for dual channel regardless?

All socket 939 chips currently are dual channel yes. There are new 3000,3200,and 3500 .09 939 a64's that just came out though. Based on the improvements to these new chips, they seem to perform a bit closer to 754 counterparts.

Honestly I would go 939 and grab a 3000 .09 or 3200 .09 socket 939 chip. The winchester has some small improvements that give it around a 2-3% boost in some cases and anand reviewed the dual channel performance which ranged between 1-7% in games with an average around 5%. So if extra 200mhz does infact give around a 10% boost, the winchesters are pretty much closing that gap. Not only that the new .09's seem to be great overclockers and of course you get the 939 upgradability.

I would bet that the socket 939 3200+ is a faster processor, OC it 200 MHz and have a even faster proc. Socket 754 is being faded out so dont bother with it.

This isn't entirely true. Socket 754 is going to be the base for the sempron chips. But your right, a64 wise you probably won't see a new a64 on this socket any time soon.
