Overclocking Performance Update

[Pixle]

I've been looking into buying a AMD 2500+ barton because of the overclocking ability. I had a question about the actual performance that it would show.

Would overclocking an AMD 2500+ to 3200+ levels yield the same performance as a 3200+? Are their any bench marks out their that could show a comparison in game fps and scores.

If the 2500+ is oc'ed to the 3200+ then they will perform exactly the same. They will both be in essance, the same chip. The 3200+ is just clocked at 2.2ghz by default. You will OC the 2500+ to the same 2.2ghz so it will perform exactly the same.

Heh...I think Jason also explained why we OC

get the mobile version, it's better.

Here is an interesting article I found.

http://www.flickerdown.com/stewks/articles.php?articleId=52

It shows a 2500+ barton overclocked to 3200+ against a A64 3000+.

I'll let everyone build their conclusions - but the 2500+ barton definetly seems like a better buy than buying the A64 3000+ for 200+.

70$ vs. 220$

and about the same performance.

I only wished they would have showed some game fps.

Be careful guys, he mentioned the A64. An overclocked Barton will not match a 3000 A64. The Barton and the A64 Newcastle are different cores. The A64 Newcastle has a lot more punch per clock cycle.

The 2500's come top locked so you can't use the multiplyer for over clocking. No big deal since the bigger gain is by overclocking it by 10 x 200 FSB. I would rather get the mobile 2600 Barton now anyway.

i would really like to see a review comparing an A64 3000+ to an OCed barton running @ 2.5 ghz....

arent all the mobile bartons unlocked?

Should be... dum dum dum

/runs to pick up a mobile barton before they put the locks on

If the A64 is at stock speed the Barton@2.5ghz+ will beat it in most areas. The thing is, if you can overclock a mobile you can overclock a A64 I have my 3000+@2.4ghz and it's definitely faster than the overclocked mobile for gaming. Having compared it vs a Barton@2.43ghz 422DC-DDR synch mode the Barton just won't match the A64@2.4ghz for most games. Just have a look at the benchies from a A64 2800+ vs XP3200+ and you see it win despite the 400mhz disadvantage.

The difference is in the mem bandwidth performance and cache. The P4 has been out for how long? P4C 2.8-3.2/3.4, and people were bying the Athlon XP2400-3200 when the P4 was compared to the XP then. The A64 directly compares with the P4C series. Alot of people seem to be thinking the A64 is stupendously great, and for what it is in it's design it is, but the P4C still hangs with A64, and still beats it in several catagories - so if you think about it in that way. No reason for me up upgrade to A64 really - even though certainly it's faster. AMD XP still hangs where it counts. Im games. A64 is faster, but it's much like a P4C which has been out along, long time - and people were buying the Athlon XP when it was compared to the P4C a long time ago. A64 is no faster than the P4C in the grand scheme of overall performance. Slighly ahead in some catagories, and P4C is ahead in others.

I did not mention the mobile 2500 but the 2500 Barton which I thought was originally asked. And from what I heard the 2600 mobile over clocks better, but that just could be rumors from members.

 

[McMadman]

Not all barton 2500+'s are capable of overclocking, mine will do it to 3200+ but it's not rock solid (prime95 will kill it after 1-3 hours I just haven't tested if it's voltage or cooling.

Mine is also one of the later ones that is multiplier locked.

all mobiles are unlocked
and I'm sure the actual difference between a mobile @ 2.5 vs a64 @ 2.4 is not noticeable AT ALL. MAYBE 3 frames more

That doesn't agree with my experience. There is far more than a couple FPS difference between my A64@2.4ghz and my Barton@2.43ghz 422DC-DDR synch mode, and I seriously doubt a little higher bus and 70mhz clockspeed would drastically make up the difference. BTW, I just setup this 2400+ mobile with an AN35NU last night and it takes 1.75v@2.2ghz just to pass P95TT :frown: @2.3ghz 1.85v it couldn't even go an hour!!! I've owned 2 t-bred B's and a Barton in the last 18months that would all do 2.4ghz stable on that voltage so this is a DUD. 2.5ghz maybe average but they don't all do it I can tell you from experience. Either that or my definition of stability and their's is in drastic oposition to each other

 

[Boztech]

The problem when overclocking is people don't seem to take into account all the nickle and dime stuff it takes to get that overclock. You think, $80 Barton vs $200 A64 is going to be cheaper.

Then you buy the Barton. Then you spend $60 on a heatsink, fan, and AS5. Then you spend $80-150 on a more powerful power supply. Then you spend $240-300 on faster, lower latency ram. And you may even spend $40-100 on all new case fans and a Rheobus. The crap adds up.

 

[someone16]

Yup, overclocking is basically a hobby...I was O/Cing my barton and found out my old PSU couldn't handle higher voltages very well...so I switched to an enermax. Then I find out it's too hot, so I switch to Aeroflow + AS5. Then I get lots more case fans for airflow...
But depending if you can control yourself from buying all these things...you can get good performance for a cheap price.

 

[howdyduty]

For value, tough to beat an XP OC'd and running at 200mhz fsb. Find a good and cheap combo and you will get value.

 

[will889]

Yep, both A64 and P4 are clearly faster than the ol' XP, but it's not a bad chips for games and not so demading apps still. Quite a bargain nowdays.
