some of you have been waiting for has finally arrived, the first pictures of AMD's Radeon HD 4890 has made their way online and they're even from someone that knows how to use a camera, unlike Mr Blurry Cam.
There really isn't much to say about this "new" card, as AMD has only done some minor changes to the PCB, mostly to cope with the extra power demands for the higher clock speeds compared to the Radeon HD 4870.
The expected clock speeds have also been confirmed with the GPU clocked at 850MHz, which is 100MHz faster than the Radeon HD 4870. The 1GB of GDDR5 memory is clocked at 975MHz (or 3,900MHz effectively), resulting in 75MHz or 300MHz faster than the Radeon HD 4870 depending on how you want to count.
It's not much more to say at this point and we'll just have to wait until AMD seeds the final cards for review before we know how good or not this card really is and if it'll be worth the cost to upgrade to.
