HD4870 1GB benchmarks?

Is there any 4870 1GB benchmarks? I cant find any and I see already these cards selling. Its very interesting to me what kind of advantage they have over the 4870 512MB and if they are getting closer to GTX280 performance

Anyone?

I have not seen anything on the 4870 1gb. Only the 4850 1gb, but no benchmarks to with those. I will tell you that if you play at very high resoluions then you can expect to see an increase in performance, but dont expect it to be substantial unless they change the clocks speeds along with the additional memory. The 1gb of memory is somewhat, for lack of a better term, "bottlenecked" by the 256bit width that the 48xx series architecture offers imo (I suppose I could be incorrect). Hope this helps.

Different architectures use the memory differently though I think. 8800GT/9600GT barely make use of 1 GB of memory no matter what res you play at (based on benchmarks), but 4850/4870 may be different in that aspect. We'll have to wait and see though.

right

I have overlooked it and didn't notice its preorder

That is true to an extent, but we will have to see some benchies to see if speed alone can address that amount of memory through the more narrow path. Time will tell.

Agreed. This is finally what I have been waiting for to fully utilize my 24" monitor.

you can pre order it and it may not be out yet, but shouldnt a website such as Tom's Hardware or another like it have gotten their hands on one already and benched it already? they usually get their hands on these things well before they hit production so they can reveal the results and the companies who make them let them get benched by Tom's Hardware and others so they can try to sell them before they're out... it's a dirty game y'all

I'd expect a significant boost at 2560x1600, and even 1920x1200 with AA in more recent games. I wouldn't expect miracles though, and I'd be surprised to see any difference at all at lower resolutions (<1920x1200).

superclocked versions of the 4870 are going to be available soon with core speeds up to 850 and memore over 4GHz. 4GHz is more bandwidth than the GTX280 so we will see raw core chip comparison in performance

Yea those will be some beasts! lol

5GHz is such a stupidly high clock speed for a factory part.

I love it

i agree too!
