A Couple Athlon Questons

[royal05]

OK, my brother seems to have chipped the core on his processor so he needs to get a new one. I have a few questions to help decide which one to get. I tried searching for the answers in the FAQ and by doing searches, but didn't find the answers I was looking for.

If I remember correctly, non-XP Athlons above a certain speed (1.2GHz maybe?) have their L1 bridges already connected, so that you don't have to do it manually in order to overclock it. Is this true, and if so, what is the speed? If not, are there any that have the bridges pre-closed, and how can you tell which ones?

How much of a performance increase is there between XP processors and regualr Tbirds? How much of a performance increase will I see between a Tbird 1.33GHz and an XP 1500+ (@1.33 GHz)?

If somebody out there has the answers to these questions, or can point me to someplace that does I would be delighted.

Maybe this will help...? Most all 1.2Ghz Athlons are unlocked... As far as I know all 1.4`s are for sure...? (dont qoute me... 🙂 ) Use a magnifying glass to be sure on the bridges... 😉 If your MB is using Sdram and you compare an XP to a reg Athlon I dont think its much of a difference clock for clock...? DDR is a different story... (Bandwith is the key...)

Besides benchmarks, I don't think you'll see a whole lot of difference between a 1.33 tbird and a XP 1500+. Technically, the 1500 should seem 167 Mhz faster. It actual practice, at these speeds, that difference is minimal.

Other thing that matters, maybe:

thermal power: the new Xp use less current, thus less heat. that's something to consider, you might slow even down the fan....
(using an apropriate resistor )

and they have muchos more potential to OC! yeah, the fun beginn's....

As far as I know all the latest 1200-1400 T-Birds which were sold in the last year came factory unlocked, especially the AXIA and AIJHA steppings.
If you are using the same platform for both AXP 1500+ or T-Bird 1.33 it will be hard to see any difference. If you saw tom's hardware benchmarks you could see that the T-Bird 1400 outpreformed the AXP1500+ because of it's higher clock speed so I think that the SSE which had been added to the AXP didn't add much of preformance to the new chip and if you take an unlock 1.33 T-bird you will be able to overclock it to 1466 and above without doing anything special(just raising the multiplier). The only advantage of the AXP over the TB is that it preduces less heat then the latter.

Hmm, I just upgraded my Duron server to a Athlon 1.2g about 3 days ago, on an Abit KT7A RAID board (pre 1.3 rev). Don't know what the stepping is, I didn't realize some were unlocked. I'll have to check it out later and see what's up.
