AMD To Launch RV770 On June 18th

4870 XT is the 9800 GTX competitor

'The RV770XT should be as fast as a non-overclocked version of the Geforce 9800GTX 512MB or around that speed. This means that the RV770XT might be a bit faster or a bit slower than this Nvidia offering.

However, the RV770XT based 512MB cards won't be able to beat overclocked Geforce 9800 GTX 512MB cards'

Oh dear, hope not. :(

Same, but then according to the Inq, Fudzilla's arch nemesis (:p), the GTX280 card is going to be too slow mostly due to clockspeeds, the RV770 will be a similar speed, and R700 is going to walk all over the GTX280.

Frankly, the way I see it, the 4870 will probably beat the GTX260 (the clocks on the GTX260 really do look like they'll cripple the card something nasty), which in turn will be more powerful than the 4850. The GTX280 will be the most powerful over all until R700 comes, but it'll be so expensive and power consuming that it'll be unattainable for most users. As for R700 vs. the GTX280, I think it'll be fairly close, but more game dependent than anything else.
 
I can't see the r700 being to expensive as ati's strategy is to compete aggresively with nvidia on the price front. Top of the range ati cards have always been cheaper than nvidia cards for as long as i have been into pc's whether they were better cards or not.

I think there is more chance of pigs flying. But we'll see.

From the specs the 4870 seems far too fill-rate limited to compete with the 260.

I don't think my thoughts are unfounded here - the GTX260 has worse specs than an 8800 Ultra in a lot of places. :\

Less shader power, less bandwidth, less texture fillrate... It is not looking pretty, mostly because the card has such low clock speeds.

Also, to be fair, the texture fillrate is doubled since the days of the 3870 on the 4870, the pixel fillrate shouldn't be too much of an issue, since much of the calculations that were traditionally done on the ROPs have been moved to the shaders since R600 (for example, Antialiasing).

Edit: For example, the 4870 has around 1TFLOPs of shader power to dish out, the GTX260 is only putting forth 575GFLOPs. That's almost twice as much, the 4870 also has more memory bandwidth than the GTX260 (100GB/s vs. 120GB/s)

The r600 architecture also had far greater shader power than G80. Internal inefficiencies came out to haunt it.

Don't get me wrong, for scientific computing (which I'm into through my job) the r600 was great, and the 4870 should be too. I just don't see them competing with the nvidia cards in gaming.

One simplistic way to look at it is this. Nvidia and ATI both know very well what the other is producing, and price their cards accordingly. The 4870 is not priced to compete with the GTX260. Market pressures usually rule over all other factors.

Anyway, we will have to wait for benchmarks to see so there is little point in arguing now. But, I will say this: If the 4870 turns out to be faster than the GTX260 in a majority of modern games, I will (at your request) start a thread here entitled "I am a retard" and link to this post, so everyone can see that you were right :) It isn't going to happen though :p

Lets hope the 4870 provides good competition to Nvidia, would idealy love to get 2x4870XTs or an 4870X2, but it all depends if the G200 is still a lot faster... then it may proove to be easier/quicker to waiting for ATI on there X2 version.
 
well i will see at august 10 if 4870x2 will come out at that time and how much are 4870xt or 4870x2 will be faster then 8800gts g92 on 22" monitor.

ati cards should overclock well and it would be nice to have a card that runs @ 1ghz core and i heard shaders will be unlocked or something ? so you can clock them to ?
 
Only thing on paper the 4870 seems to lag behind in is the number of ROPs and texel fillrate, everything else is a good improvement over RV670, but all this speculation is wafer-thin without any real-time benchmarks.

Well said ;). The proof will be in the pudding so to speak.
