That si the only difference i can see, which means the 4850 is just an underclocked 4870. So you should be able to just by a 4850 and overclock it?

Or are they using difference core processors? I'm confused

But either way, i really hope these take off! Seems like ATI are trying pretty damn hard this time round.
The RV770 pro (4850) will be equipped with 512 MB of GDDR3, while the RV770XT (4870) will have 1024 MB of GDDR5

Ahh man

I knew that as well, but it just totally slipped my mind! Rep + for bumping my brain Oh and awesome album on your avy!

So does anyone know if these will be using the same core then? With the code name of both being RV770 it would lead me to beleive they are using the same core. But then again, GPU names nowadays don't relate to anything and generally confuse the crap out of me lol

Can we say 2900 Pro and 2900 XT? I am thinking it is a similar situation.

4870 GPU: RV770XT
4850 GPU: RV770PRO

They are , apart from the gpu/shader/mem clock, basically identical.

This is certainly a slap in NVIDIA's face. AMD's mainstream chip can do more FLOPS than NVIDIA enthusiast chips
lol, very funny

AMD should be happy if HD4870 manages to compete againsts the Nvidia 260
