HD 4890 can be overclocked to 1GHz

AMD is on the verge of the new HD 4890 video card to be introduced. This card with the RV790-GPU on an improved version of the RV770 HD 4870. The RV790 would easily a clock speed of 1GHz can be achieved.

In the Far East are the first HD 4890 cards, which officially until April 9 to be delivered, whether in the hands of consumers now. The Chinese PCInlife forum even some overclocking results of the HD 4890 have emerged. The GPU has a standard clock speed of 850MHz and memory at 975MHz is overclock. A Chinese PCInlife-visitor knew the GPU without special tools to clocks to the magical clock of 1GHz. The gddr5 memory could be overclock on 1125MHz.

The stability of the overclock map was tested using 3DMark Vantage. The eXtreme setting was achieved a score of X5480, which the card slightly slower than Nvidia's GTX285 would be. To map the cooling fan to keep running at full capacity, but whether that was necessary is not clear. After the introduction of the HD 4890 should show whether all copies of the 1GHz limit easy to exceed.

the question is what the scores are standard.
5480 at 1GHz is nice but what does it stuck
(bet 4500-5000)
5 460 * 0.85 = 4 641

and as a GTX 260 216 is already in 4900 (and 4870: 4173)

thanks.

then the 4890, so actually already struggling to keep a GTX 260
and a GTX 275 is a lot faster. and 285 also.

though the price a bit lower, the performance that also
the score is slightly against me in any case.
though I will be 1 next to my 4850, I think cramming
I wait for the next series. ervanaf is how it runs

You can see that so completely wrong.

The HD4870 performs slightly better than the GTX260 216 in games.
The HD4890 performs 20% better than the HD4870 in synthetic benchmarks.
You could thus argue that the HD4890 also 20% better score than the HD4870 and GTX260 216

the gtx260 216 and the 4870 hand slap to 1gig per game, one time is faster than the ati nvidia again. Most sites give a win to whichever benches they run and how much value they attach.

In my humble opinion says very little about synthetic bench. it is an indication of what the PC can, but it is not sure if that also works well with games or other graphics programs.

It is not only the card but the driver is very important, plus the settings on the PC. That is more consumer oriented differently.
