Damn all those SP's and only 16 ROP's :shadedshu

but, it's only one GPU (although granted it's a small number) brandishing the RV moniker

although, I wonder when we'll be seeing the R700. Based on that info, it doesn't look like the R700 will accompany the HD4ks series.

it says that they use the RV770 though

this is quite early for the new series specs to be released

yeah, on these newer series . . . but we still haven't heard much about the R700 core; except that article there states the R700 will contain two RV770 cores. I guess we'll have to see as more info comes along. I'm just a little surprised to not see anything about ATI using the R700. I had kinda thought it would be packing on the 4870, or even a 4870x2.

weird

on the HD 4870 it says it can output 108 GFLOPS
and on the HD 4850 it says 816 GFLOPS

something doesnt seem right..

Probably meant 1008 GFLOPS, since 4870x2 is 2016 GFLOPS.

yea sorry, someone will point it out to them though

Impressive stock freqs.
>1GHz GPU + GDDR5 @ DDR-4400 (2200MHz actual)

Excuse me, since when GDDR4 does 2200MHz?

since 3870?

ewww 16 ROPS......eewwww

not to mention it seems theyve stuck with 256bit memory, which wont do them any favours over 1600x1200.

imo next gen cards need at least 32 ROPS, then we will see some ball busting performance.

wolf, it depends on how the chip and its drivers work, a little example, the kyro2
http://www.tomshardware.com/2001/04/25/a_speedy_tiler/page2.html

due to the rendering method used it could get away with sdr ram insted of pricy ddr, this is tad ammount to 128bit vs 256bit or 256bit vs 512bit memory enterfaces.

as to rops, as the x19*0 cards showd even when nvidia added more rops they didnt win the battle, again its all in how the hardware is used, the current 2900/38*0 cards have a design miss caculation that means they never get fully exploited by current games, but the Rops are not the problem as i understand it, its the fact that you gotta code spicificly to take advantege of the way ati layed the current chips out or u dont see the benifit of the massive number of shaders, this could easly change if they do things properly.

I hope the next ati line rock and like the kyro2 proove to be an example of efficent elegant design insted of the nvidia bruit force method(anybody can do bruit force.....its just expencive)

256-bit memory bus, maybe but isn't that a 4.4 GHz memory bus? ~140 GB/s?
