DAMMIT Slash Prices Instead Over Cooling

I agree. I'll guess we shall see soon enough if ATi is back in the game. Fingers Crossed.

I'm not so sure the GT will dominate these cards. We have already seen from Unreal Tournament 3 that the ati cards do have some kick in them and like I said before if they really "fixed" aa then the 3870 should dominate the gt in that area because of it's superior bandwidth.

Superior bandwidth? Umm they are on a 256-bit bus from what I remember reading so they don't have any more bandwidth than the GT

yeah these people wit hthe gt's keep telling them selves they have something, but really, its just a mid end prices card that performs well, at most 64gb/sec of bw. the nv did the mone up and released to new 8800gts which performs even better than the gt... ati... better have something.

they do have more bandwidth... the 8800gt has at most @2ghz 64gb/sec where are the ati card will have


2000Mhz <- Effective Memory Speed, "Actual 1000x2"
256(bits) <- Memory bit * 2,000,000,000(Hz) = 512,000,000,000 bits/sec
(512,000,000,000/8) / (1000*1000) = 64,000MB/sec 64.00GB/sec

do the same for the ati card

2400Mhz <- Effective Memory Speed, "Actual 1200x2"
256(bits) <- Memory bit * 2,400,000,000(Hz) = 614,400,000,000 bits/sec
(614,400,000,000/8) / (1000*1000) = 76,800MB/sec 76.80GB/sec

Hope they have something. Im not regreating my purchase at all.

(512,000,000,000/8) / (1000*1000) = 64,000Mb/sec 51.20GB/sec

do the same for the ati card

2400Mhz <- Effective Memory Speed, "Actual 1200x2"
256(bits) <- Memory bit * 2,400,000,000(Hz) = 614,400,000,000 bits/sec
(614,400,000,000/8) / (1000*1000) = 76,800Mb/sec 76.80GB/sec

so it has a bandwidth increase of 8.3%

Subtract 200Mhz from the ATI clock to get actual performance due to the GDDR4 performing on looser timings. It was seen with the 2900XT with 1gig GDDR4 performing basically identical to the 512Meg GDDR3 model, yet it had a higher clock. Not arguing about the difference but just from what was shown in the past that GDDR4 doesn't really make it that much of a selling point on a card currently.
