754 vs 939

[Andrzej_Pl]

First, I'd like to say hello, as it's my first post in the forums 😉

Well, I've now PIV 2,4 Northwood and I think of upgrading to Athlon 64. The problem is, that I don't know which socket 939 or 754. The PCI-X is not the factor, because I don't plan to switch from my FX5900.

I'm also not overclocker, so I really don't care about it

What I want to know is that if the performance difference between those two slots is worth the price difference 😉

Ok, this 754 vs 939 has been too much debated here!

AGP/754 = Budget and/or short-term investment.

AGP/939 = You want to keep a HIGH-END AGP gpu for quite a while and you want to be able to upgrade to a faster CPU later as needed.

PCI-EXPRESS/939 = Long term investment. CPU and GPU will be easily upgradable.

By the way, there is not much difference in price between 939 and 754 setup. And for your information a S754/3000+ is faster than the S939/3000+ in most situation because it is 200MHz faster.

I personnaly think that since S939/PCI-EXPRESS affordable mobos are out (nForce4 NON ultra/sli). A64 S939 is definitly affordable, but you have to spend on a PCI-EXPRESS gpu.

That being said...
s754 is the best price/perf. Yes, PCIe is replacing AGP as the standard for video cards, but AGP cards will still be available for a while - ATI is going to release the X800XL and 850XT in AGP models. Major limitation for s754 is that the chip will not be produced beyond 3700+. Even though to won't go beyond 3500+, the 200Mhz advantage of the s754 is significant and if you OC, you can get the 3400+ to 3800+ performance. If you want to keep AGP, then I suggest you go with a board based on the nF3 250 chipset for a s754 system, good examples are the <A HREF="http://www.newegg.com/app/viewProductDesc.asp?description=13-127-190&depa=1" target="_new">Abit NF8</A> or the <A HREF="http://www.newegg.com/app/viewProductDesc.asp?description=13-136-147&depa=1" target="_new">DFI Lanparty UT NF3 250</A>.
For s939 with AGP, go with the a board that has the nF3 Ultra chipset, example is the <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=13-123-230&depa=1" target="_new">Epox 9NDA3J</A> or the <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=13-128-263&depa=1" target="_new">Gigabyte K8NS Ultra-939</A>.

Hummmm... I thought it was 3700+...

-Always put the blame on you first, then on the hardware !!!

I could be wrong...let me do a little research and get back.

:redface: considering you can buy a 3700+ right now, I'd have to say that the s754 will be able to reach 3700+...

Well, I was told in the store that "754 is dead, and the dual channel for 939 makes it much faster mobo", but I wanted to ask in some reliable sources, and not trust the guy who sells stuff 😉

A s939 that is at the same clock speed as a s754 will be faster due to the dual channel. The issue is that similarly performance rated CPUs are not at the same clock speed - the s754 is clocked 200Mhz faster and the dual channel just does not make up for that speed difference.

And the Athlon XP series has been dead how long now? Yet you can still buy them nib (new in box). Dead is not the proper term in this case; product production run and development end date being determined would be a much more accurate statement.

I still have resevations about s939 boards. There isn't an agp board, that I feel good about recomending to a customer.
