Can an O/C mobile XP 2500+ *realistically* match a Athlon 64 3400+ ?

[BEIF]

Obviously, from reviews, this Mobile 2500+ Barton is a *great* O/C chip.

=> so ...... given an Athlon 64 3400+ is a 11 [fixed multiplier] x 200mhx = 2.2gig what sort of O/C would a Moblie 2500 need to achieve in order to get the same performance as the Athlon 64 3400+ ?

=> is this even possbile ?


For example:-


=> would I be Mobile Barton 2500+ [which has an unlocked multiplier] running at say 2.5gig [ 14.5 x 172 ] equal the perfomcne of the 2.2 gig 3400+ ?

=> ie: would the "extra" 300mhz raw speed *compensate* for the 64 3400+ extra cache/memory/efficiency ?

TIA,

If you could hit 2.5ghz, it most likely would match. Certain things such as memory performance probably wouldn't equal the Ahlon 64, but overall App performance should be quite similar. I'm not familiar with the Mobile 2500 and really don't know if it is that good an overclocker or whether its' performance is on par wih the desktop Athlon 2500.

acording to sandra mine is = too a FX53 in everything but memory bandwidth. Now I know this is synthetic but it should be atlest close to acurate

It depends on what you want to do with it. For gaming it will never come close to the A64.

Hi FallOutBoy525


Thanks for your info - may I please ask:-


=> what m/b and DDR ram are you using ?

=> what cooling are you using ? air ? water ?

=> with your Sandra scores, is it equal to a 3000+ or 3200+ or 3400+ ?

=> I presume you meant FX51 *not* FX53 [given that FX53's arent out yet] ?


Many thanks,
Ben "BEIF" Ifin

specs are as follors:

NF7-S
Mobile Barton 2400
Single 512mb Crucial 2700 running fairly loose timings (this is holding me back and will be my next Upgrade, hopefully to 2x512 3500 or better)
Vantec Aeroflo HSF
and I'm compaing too the FX 53 in the sandra test comparison.

BEIF- what type of computing are you looking to compare performance in? Sandra isn't really a good indicator.
There are certain 2D apps where an overclocked 2500+ can compare to an A64. If you are interested in gaming performance, then like I said in my previous post, the 2500+ really can't compare to an A64. I know this because I have a 2500+ at 2.5 ghz.

Thanks very much FallOutBoy525.

I am looking at an Asus A7N8X m/b as it has 400mhz fsb, dual DDR, on-board LAN, passive NB sink [quiet] and is *reasonably* cheap - only problem I *think* is that the NVidia based boards - this is a NForce2 SPP Ultra400 / nForce2 MCP shipset combo - *appear* not to have a AGP/PCI lock

Pelikan

I will be using it for multi-track digital audio recording with extensice soft-synth use and extensive in-line efx plugins => in short, these are *extremely* CPU intensive tasks - the Athlon 64 3400+ is simply out of my budget for now - thats why I am *hoping* / *thinking* that a mobile barton 2500+ running at 2.5gig would/could approximate [or maybe equal] the CPU processing efficiency of an Athlon 64 3400+

Dapunisher did some comparative benches between a 2500+ and an A64 in this thread.

Nforce 2 Ultra Mobos have AGP/Pci lock, what you tell is Nforce 3 (which seems to have only AGP lock). About buying a 2500+ to run at 2,5ghz.... well, you have to be really lucky to reach those speeds (maybe mobile is easier, but you can't trust in overclocking results), and spend lot's of money in buying performance memory to run it 1:1, which is quite important for K7s to perform at their best and not to have high latencies with the memory controller.

Why don't you buy A64 3000+ and overclock it. @2,2Ghz it should be really fast and very close to 3400+ in almost everything for much less money.

 

[BEIF]

Hmmmmm ................ very intersting benchies at that link.

I wonder then:-

=> what is the cheapest available Athlon 64+ motherbaord at the moment ?

=> are there *any* dual-channel DDR Athlon 64+ boards currenlty available ?

Ben

 

[McArra]

A64 has no dual channel, but it doesn't care about it neither. The only one with dual channel interface is the FX51 in socket 940, but it costs quite a lot. About a cheap Mobo for A64, I'd go with the Shuttle aN50 as it is one of the best overclockers out there and it isn't expensive at all.

What kind of voltage are you pumping through that chip? Actual and BIOS settings if possible, my NF7-S likes to undervolt the cpu and overvolt the ram.

Im pretty concerned as to how long those mobile chips will last with so much voltage through them. Looking at some posts, 2V to get 2.7Ghz... default voltage is only 1.45V. Scary thoughts.

EDIT: What BIOS version are you using? Compatibility may be BIOS version dependant.

 

[pelikan]

Here's an Anandtech article with some more good benches. Depending on how far you want to overclock an A64, the ECS ($70.) and Aopen ($90.) have very good reviews. The Shuttle that McArra recommended doesn't cost too much more and along with the Gigabyte seems to be the best overclocking board.

The A64 3000+ is definitely a great value and the smaller cache compared to it's big brothers shouldn't be a factor anytime soon. While my Barton did prove it still has plenty of muscle in synthetic benchies, POVRAY, and SETI, the A64 kept it very close despite lower clockspeeds and less heat and voltage, and has really impressed me in real games. The difference in Halo went from a little chop in big fights to completely smooth play. Far Cry looks and plays very nice@10x7*my LCD's native res* 4xAA 4xAF*enabled through console command* PainKiller looks great and plays better, and my DVDShrink times are faster too, probably mostly due to the better HDD performance compared to my nF2 board. I just ordered a AN50R and Raptor so I'll update that thread with those in the mix ASAP.
