I see two Athlon 64 2800+ chips on Newegg with same price as of this morning. What are the difference between the two? only difference I can see from their listing is the model number:
ADA2800AEP4AX
ADA2800AEP4AP

What does the X and P at the end denote?? Is one better than the other?

Thanks.
 
In the specification on newegg, they are exactly the same, 1.8GHz with 512K cache....
Only difference is the model and item numbers....
 
The AP is a C0 core, while the AX is a CG core. the cg is the newer revision that tends to overclock better and put out less heat.
 
OK. so AX is the better one and the one i should get?
The price for the OEM chip is right now $137.00. Do you see the price going down at all anytime soon? or is this pretty much the lowest it will get for these chips??

Funny thing there's a lot of reviews on newegg for the AP model, but none for the AX model.... or is it by the time AX came out no one was getting 2800+ but higher clocked chips?

Thanks!
 
Yea, definately get the AX. it will run cooler and clock higher if you plan on ocing it. i think price cuts are coming for amd chips, but i think it was only the higher end models getting the price cuts due to the introduction of the 90nm cpus. even then, the lower end models wont see anything significant. the ax is newer, and it also very likely that people didn't know the difference between the two chips and just posted a review for the cpu that had the most.
 
Word on the streets is October 15th AMD is scheduling another price drop

Now, this isnt in stone, I'm not trying to say this will happen....

Looks like high-end 754's and 939's are getting it, if the article is anywhere near accurate.
 
Ok. Thanks for all your help guys!!

I have another questions though :)

I currently have Antec 350W or 380W power supply. Do you think this is enough for the 64 2800+?? or do you think I need more power?

Also are there a big difference between the VIA chipset MBs and Nvidia chipset motherboards? Which one do you guys recommend?
 
That antec 350 should be enough, unless you have like 4 hard drives and a new video card. without knowing ur specs its hard to tell. The a64 isn't nearly as power hungry as the prescott, especially the 2800+. At stock speeds the nforce 3 250 and kt800pro are nearly identical. nforce 3s tend to have a better apg/pci lock, but that only matters when overclocking. basically, choose on features and price.
 
Thanks again MetsFan.
Funny you mention 4 harddrives cause that's what i have right now hehe.
I have P4 1.6A @ 2.13Ghz, 2x60GB, 2x30GB, and TI4400, 2x256MB DDR333. Everythings been running fine for a loooong time.

I was thinking about just getting the 2800+, new MB, and new RAM.
(I was also looking at the Mobile XP 2500+ cause I don't really play games....)

How about the Retail boxed 2800+. Will they be AX or AP?

Just depends. Most will be C0. If buying retail have them look. Processors face the outside of the package.
