754 v 939 : Getting poor 754 systems

[FatRakoon]

This first came to me when I downlaoded the TRIAL of XP64.

I threw it into my MSI Neo2 & Winchester 3200 PC and found that the system was a speed monster compared to XP32, even though I was unable to find half the drivers for the system, what testst I was able to do, were VERY encouraging.

Anyway, a fewmonths passed, and I had eventually found almost all the drivers I needed, bar the Modem, and so I bought XP64.

Now, not being willing to pass over my main PC ( MSI Neo2 and x2 4800 ) to 64BitXP, thats still on XP Pro, and the XP64 is now on a DFI LanParty UT250 along with a Clawhammer 3700, but the thing is, that on the Clawhammer, its no faster than plain old XP?

I have done a bit of piddling about recently with it, and running it against XP32, setting it up exactly the same on both XP32 and XP64 and one thing I have had pretty much 100% the same results all across all my PCs, and that is, that the Socket 754 systems are no faster with XP64 or XP32... They are pretty much the same, yet the 939 systems do have quite a substantial boost!!!

Why is this?

Its almost as if the 939 systems really are 64Bit while the 754 ones are only emulating the 64bit instructions?

The systems I have been using for the mesing about have been

MSI Neo2 - Winchester 3200
MSI Neo 2 - 4800 x2
ECS NForce3+ : Sempron 3100
DFI LP 250GB UT - NewCastle 3000
DFI LP 250UT Again - ClawHammer 3700

All at stock.

All have 1GB RAM, using a dual pair of Corsair 4400 Platinum & TwinX, OCZ, or Crucial, and all have been played with at stock speeds.
All have been installed with 2 custom CDs ( XP32 Pro SP2 and XP64 SP1 ) with the very same winnt.sif custom config, to Maxtor 40GB ATA133 Drives.

Any clues, or am I right in assuming that Socket 754 just isnt any cop compared to 939?

Hi

Can only say my opinion but ive not noticed any difference betweeen a 754 & a 939 system running x64 but do remember the nforce3 wasnt as good as the via chipset speedwise on the 754 sockets ... that could be your answer but i never owned a nforce3 setup ... my systems are MSI Neo 2 (VIA KT800) chipset best at the time & nforce 4 ultra .. both fly on x64

dont suppose that helps but ive tried

SSE3 extensions, performance increase of about 15% against older 754 systems, dual channel 939 vs single channel 754, chipset (as mentioned above). All of these must factor in somehow.

I do have one VIA Motherboard, and thats a Gigabyte K8 VT800M... I did have 2, which is why I then got a Clawhammer 3700 and a Sempron 3400... The other Mobo went with the Smegpron.

Now, the performance of that Mobo was pretty bloody naff!

I will admit somethign here, it is quite probably a big factor, but my other systems are all fairly quick buggers... Winchester @ 2.5 ( has done 3Ghz in tests ) a couple of XPMs @ 2.6 & 2.7, and an XP @ 2.9 to name a few, and these are still in my posession, so going to a stock system,. no matter what it is, will feel a little slow I suppose?

Anyway, as I said, the speed of the VT800M Mobos were lacking something, the ClawHammer was making up for it in a lot of ways, but they still felt poor.

I then went for the DFI LanParty 250GB UT Mobo and found no real advantage other than allowing me to clock the knob off the Sempron, but generally, the speed was no different... I have not benched them against each other to be fair, and the HDs I am using are not the same, so that may also be somethign to check out.

I do not have a 754 and a 939 CPU that are identical, which is a shame, and I have no intention of wasting money on any more Socket 754 stuff... I only got into Socket 754 stuff purely because the first of those VT800Ms came along for a fiver, and a mate gave me another one, and I am not the kind of guy to have somethign and not use it.

Also, to be fair, gaming isnt that much different really... Where I do see the main chunk of difference, is on the Desktop... Loading up a poo load of large memory hungry apps, and jumping between them, lots of RAM, lots of disk access and so on.. The 754s dotn really cut even that, and in fact, the Barton 3200 & NF7S I find is at least twice as fast as going in/out of multiple apps than the Sempron, and the Winchester has next to no slowdowns, while the 4800 has none at all.

Nah, if its a choice between a Socket A Barton, and a Socket 754 Sempron system, then I would have to chose the Socket A anyday.

This is worrying and confusing conjecture.

My new Socket 754 setup (A Venice Core 3000+ @ 2.7GHZ on the aforementioned DFI UT NForce3 250GB) feels more responsive and certainly benches faster than my [email protected] on a NF7-S V2.0 with the same memory and GFX.

Could it be that the SSE3 and the speed of the HTT is a factor?

 

[FatRakoon]

It would be faster... Its 2.7 against 2.4 and its a Venice too, which are noted to be quick anyway.

Now, compare it to the same speed Socket 939 and its quite likely that you will find the 939 is quicker still.

I am comparing like for like in many ways..

For example, the Newcastle 3000, the Sempron 3100 ( Both 754 ) and the XP and Barton... Also the Winchester 3200.

These are the oens in the 3000 - 3200 range, and the Winchester is way quicker than the others.

Hi there, while i have not tried XP64 as of yet i have had a couple of different skt 754 chipsets. My first was a Nforce 3 250Gb which was in my old MSI K8N Neo Platinum and when i upgraded to my Epox EP-8NPA-SLI i now have Nforce 4 SLI. I have found that the Nforce 4 chipset is a lot more responsive than the old Nforce 3. There is certainly nothing wrong with the performance of my 754 rig.

Dual channel memory will give you a minimal gain over single channel, around 5-7%. SSE3 may give you a performance boost but only if the applications that you use actually make use of it. I read an article in one of the major mags the other day about SSE3 and the other much hyped enhancements and there are hardly any applications that use it and most use SSE2 as most computers have a cpu that can actually take advantage of SSE2 and not SSE3.

A 754 A64 rig should hammer a Sempron rig and absolutely wipe the floor with a socket A rig. As for assuming that a 754 rig is'nt much cop against a 939 rig, thats just plain nonsense. My rig has actually beaten better specced 939 rigs in 3dmark06. Just check the scores in the thread in the graphics cards forums.
