HD2900XT - 80nm or 65nm?

post #1 of 10
Thread Starter 
That is the big question.

Basically, I will have the money this Friday to buy a new GPU. I am leaning towards a HD2900XT, as it is showing very strong signs (if not already) of being better value for money (and at times, better in performance than) the 8800GTX.

But saying that, I would rather get the 65nm version over the 80nm version, as that will allow for higher clocks and lower temps and power consumptions. Is there an easy way to tell (maybe by the product code) if it's 65nm or 80nm?

Maybe current, 0.5GB GDDR3 cards are 80nm, whereas soon-to-be-released 1GB GDDR4 cards are 65nm. Any comments/links?

Don't tell me to buy this and that. I am smart, and will buy a different card if common sense tells me to.

I belive all HD2900XT are 80nm while the other lower end cards are 65nm.

I believe all the 2900's are 80nm while the 2400 and 2600's are all 65

I could be wrong though

Like, I've read one snippet saying AMD/ATI were going to jump from 80nm to 65nm (with the first shipment being 80nm), but later not bothering due to that requiring a architecture redesign.

Then I have another snippet saying they are proceeding with the conversion, which simply confuses me.

From what i briefly just looked up.... it seems that the 65nm "R600"s will be "R650"s. I haven't read anything that says any 2900's will have the R650 chip in it, but thre's a good possibility that the 2950 will have the R650 in it.

Hope that helps

Simply searching 'R650' on google is enough to confuse you to death. "Yes it will." "No it won't." "Actually, it will." "Wait, no it won't."

Bah. I shall have to assume a high end 65nm R6xx or R7xx card will not exist, at least in the near future. The next few days will be a pain, deciding which card to get. I hate deciding.

I would wait around a little longer.
The HD2900XT uses way to much power and runs to hot in my opinion. Im also waiting untill the 65nm HD29*0 series are out.

This is more the question now. WILL a 65nm version of the 2900 come out? A report of AMD faking 65nm news to catch people leaking secret info to Intel and Nvidia is most intriguing.

I came in this thread ready to scream punch kick and link to google the fool who keeps asking stupid stuff that's answered in 348572908357230 different web pages....

...Then I read the initial post and got sad that I don't get to scream, yell, kick and link.
