G80 specs finally confirmed! NOT old news!

NVIDIA’s GeForce 8800GTX will be the flagship product. The core clock will be factory clocked at 575 MHz. All GeForce 8800GTX cards will be equipped with 768MB of GDDR3 memory, to be clocked at 900 MHz. The GeForce 8800GTX will also have a 384-bit memory interface and deliver 86GB/second of memory bandwidth. GeForce 8800GTX graphics cards are equipped with 128 unified shaders clocked at 1350 MHz. The theoretical texture fill-rate is around 38.4 billion pixels per second.

I thought GDD3 RAM was old/current generation? ATi previewed GDDR4 RAM in the x1950xtx to pave the way for R600, thought nvidia would go and implement GDDR4 in their G80 aswell. Is this a loss to nvidia or is there not that much of a significent jump to GDDR4?
 
Looking Good!

Im not expert but from the looks of it, the 384-bit memory interface will probably more than make up for the loss in memory clocks?
 
I was going to get 2x X1900xt to crossfire but now I'm not sure what to do.

In theory this should whip the 2 x1900xt's and use less power but I have been using ATI for a while and have not really looked at Nvidia since the old TNT's.

If these come in at £450 I might get this instead
 
768mb or ram on a 384 bit memory interface?!

Why not 1gb on a 512bit memory interface.

Just seems odd numbers.

Interesting read though as nvidia in the past always stated that the card wouldn't be unified shader based and now it is.

However I won't be buying one. Can't be doing with all of the upgrades.
 
Well i can safely say im missing out these new line of card and waitting until later on in the game to get something better for less so to speak with the price wars etc... hehehe

My 3200+ winny + 7800 XFX Extreme Extreme will do nicely for me now i guess, Core 2 Due is very tempting but i'll wait for the quad cores me thinks :p

I believe it's cost / complexity issue.
The wider the memory interface, the more layers you need on the PCB, and this adds to the complexity in the manufacturing, which in turn makes it more expensive.

I don't see why they don't go for Rambus' XDR memory. They could quadruple the bandwidth but still only use a 256bit interface.
