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?

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.

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.
