View Full Version : Athlon XP overclocking and performance

08-12-04, 02:38 PM
Well, Ive been trying to find articles covering this kind of thing, but it seems to be a lost cause.

I want to find out what kind of performance is possible with an Athlon XP overclocked to various speeds above 2.2Ghz (normal 3200+ speed). Im curious because Mobile 2500 and 2600 Bartons overclock to insane speeds. My brother just purchased a mobile 2600+, an NF7-S, and a 2x512Mb Corsair XMS PC-3200 kit (the best one). He is currently running his 2600+ at 2.6Ghz! There has to be a pretty good boost in performance from a normal 3200+, but I cant seem to find any benchmarks anywhere that go above 2.2Ghz for an XP.

What I want is GAMING performance, not 3d Marks, and I want to see compairisons to A64 systems. And I prefer scores with 6800 or X800 series cards (9800s were NOT CPU limited... the new cards are). I already know that 3dmark gives A64 users 4000 marks just because its 64 bit... I want to see real world gaming performance of highly overclock Athlon XPs vs. Athlon 64z.

I just have a hunch that an AXP running at 2.6Ghz (with 512 cache) has to be at least CLOSE to the performance of an A64 running at 2.1 or 2.2.

Well, there are a few articles i managed to discover today:

This one only got their 2500+ Mobile to 2.37 but it still comes close to A64 3000+ performance. Which is very good :)

And this one is a huge review (although mostly synthetic and multimedia benches... which dont mean squat to me), but they still only got theirs to 2.4ghz. Still performs very well though:

My system with a 2.09Ghz with 256K cache would probably see a pretty big improvement if I tossed in a 2.6Ghz with 512K cache.

Its a shame there arent more benches using current high end video cards though.

interesting. wonder how close to athlon 64 2800+ i am speed wise in games.

btw your brother, what motherboard is he using?

An Abit NF7-S 2.0, like I said :p :D

Although I don't have any benches to compare, I recently made a similar switch.

I have a 6800GT and I went from an Athlon XP 2100+ @ 1950 (13x150) with a cheap MSI K7N2-V to a Mobile Athlon 2500+ @ 2200 (11x200/1.55V) with an NF7-S 2.0. There was a definate improvement in games for me, as well as some improvements in general Windows usage. I'm only running at 2.2ghz right now because my case+airflow sucks and I want to keep the temps down. The highest I have tried is 12x200 @ 1.75V and it seemed pretty stable, but as I said, the temps were a bit too high for my liking.

I think the cost of the mobo+cpu was worth the improvement I got (even at 2.2GHz), and if all I would have needed was the cpu, the it would most definately have been worth the $80-90 for the cpu.

The Tech Report have another review comparing the XP-M @ 2.4GHz to A64's and what not.


Unfortunately the results aren't as good as you (and I) had hoped :( But with a higher FSB the performance might be pretty close to an A64 3000+. But unfortunately just using the multiplier, it isn't. Of course this is 640x480 and 800x600. Actual gaming conditions will bring the results within 1fps of eachother.

Not that this is worth anything, but when my mobile 2.6 was at 2.7GHZ (briefly), according to sandra I surpassed the fx53 in cpu and multimedia by a fair amount. :)

Why not just install your 6800 in your brothers system and find out first hand ?
