any real advantages of a socket 939 over a 754?

[Dr.Stevil]

a co-worker gave me a server machine yesterday that he never got around to using. I got it home and one of the raid drives was making noise and it wasnt booting linux.

I tore the thing apart, curious as to what hardware it had in it and as it turns out, it has an AMD athlon 64 3800+ (socket 939) processor (2.4ghz), though the motherboard is kind of shitty (PCCHIPS k8, only 2 memory slots, 3 pci and 1 agp) compared to my current 754 socket gigabyte mobo, although still alright for what I need I guess, just limiting with so few expansion slots.

I know the core is different and it supports SSE3 and Hyper-Transport (which my althon 64 3000+, 2.1ghz, 754 socket doesnt support I don’t believe) so would I see any noticible benefits from running that processor/mobo combo in my main rig? I literally just purchased a new case and put all my shit in it so if the gains would be minimal, I’m not going to bother as that would just be a huge pita.

any ideas?

My first impression is that you are wrong. Unless I’m wrong.

Both the 3800+ (939) and the 3000+ (754) run the same, Venice, core. Same core means same features (SSE2, SSE3, HT, L1,L2), both are 90nm.

So now you’re down to a difference of 300mhz. Doesn’t really seem worth it to me, although you could put together a really nice budget box for a few Benji’s.

heh… what do you know, you are right.For some reason I was under the impression that s754 didnt/wouldnt support 90nm chips, nor sse3 (thought I read it a while ago).

thanks for the response :tup:

I may just build it into a spare internet/work computer

thanks man

simple read’s

Socket 754

Socket 939

the way i would tell the difference is search by socket type on newegg, and see what cpus come up.

I’d bet socket 939 has some of the later and faster cpus.

You can still build a real real decent machine for cheap with 754.

AM2 > 939 > 754

yes i left out the 940, but look up what they are and you’ll see why

@super_chicken

It supports dual channel DDR SDRAM memory, with 6.4 GB/s memory bandwidth. Socket 939 processors support 3DNow!, SSE2, and SSE3 (revision E or later) instruction sets. It has one HyperTransport link of 16 bit width that can run as fast as 2000 MT/s. Processors using this socket have 64KB each Level 1 instruction and data caches, and either 512KB or 1 MB Level 2 cache.

ugh i really don’t wanna spend 20 minutes explaining this…

939, is newer technology, just read the wiki article.

oh here is an easier thing, i just for some reason over read

@754vs939

Socket 754 was the original socket for AMD’s Athlon 64 desktop processors. Due to the recent introduction of newer socket layouts i.e. Socket 939 and AM2, Socket 754 has become the more “budget-minded” socket for use with AMD Athlon 64 or Sempron processors. In comparison, it differs from Socket 939 in several areas:

* support for a single channel memory controller (64-bits wide) with maximum of 3 DIMMs (no dual channel support)
* lower HyperTransport speed (800 MHz Bi-Directional, 16 bit data path, up and downstream)
* lower effective data bandwidth (9.6 GB/s)
* lower motherboard manufacturing costs

Although AMD has promoted Socket 754 as a budget platform on the desktop and encouraged mid and high end users to use Socket 939 (and recently Socket AM2) instead, Socket 754 remained for some time as AMD’s high end solution for mobile applications i.e. no Socket 939 Athlon 64 CPUs has ever been marketed as a mobile processor. Recently however, Socket S1 has been released and is slated to supersede S754 in the mobile market through its support for dual core CPUs and DDR2 RAM.

Thanks for the spec sheet, douche
