ATI Radeon HD 4800 Series Video Cards Specs Leaked
Thanks to TG Daily we can now talk about the very soon to be released ATI HD 4800 series of graphics cards with more details. One week ahead of its presumable release date, general specifications of the new cards have been revealed. All Radeon 4800 graphics will use the 55nm TSMC produced RV770 GPU, that include over 800 million transistors, 480 stream processors or shader units (96+384), 32 texture units, 16 ROPs, a 256-bit memory controller (512-bit for the Radeon 4870 X2) and native GDDR3/4/5 support as reported before. At first, AMD's graphics division will launch three new cards - Radeon HD 4850, 4870 and 4870 X2:

I don't think it's going to be the 4870 that will be most impressive but the 4870 X2 if rumors are true that it will be 2 GPUs recognized as 1 GPU using shared memory. If that turns out to be true then:
-future video cards as we know it will change
-it will leave a Nvidia without a competing card (unless the GT200 is a dual GPU solution)
if done successfully via price, performance and innovation. This is what I really want to know most. The 4870 won't be bad IMO and at it's price it will be a competing card but it's the 4870 X2 I want to see. Only time will tell, can't wait. :p But remember there is still R800 we haven't seen/heard a peep from yet and it was talked about and rumored to be in development as far as last year (that I know of).
i hope these cards turn out good. even though i just bought my 3870...oh well
Just saying "nVidia caused more Vista crashes then ATi, so ATi must have better drivers" is false.
Edit: *-Yep I did:forums.techpowerup.com/showthread.php?t=56282
How would you know? Thats right you wouldn't.
I have two ATi computers and two Nvidia computers. I have had more display driver crashes with ATi drivers but neither have EVER crashed my entire computer.;)
Based on the driver gains ATi managed to squeeze from the R600 cores, I find their drivers very impressive, and I'd say one of the reasons NV drives are "inferior" is because they're lazy on driver releases.
