I don't understand this. They say this is suppose to be HD4850 but GPU-Z shows some really weird data. Clock is much faster and it shows GDDR5 yet bandwidth is out of whack. On the other hand score is much higher than default HD4850.

I thought HD4850 will only support GDDR3. Unless of course they really meant to say this is HD4870.

Smells like fake to me. Or at least very strange.
Actually I believe it IS the 4870

The 750MHz core cant be reached by CCC right now so unless they've already done BIOS editing, it has to be the 4870 since thats the core clock for it.

Also, 4 x 900 = 3600 MHz which is the stock mem clock of the 4870 as well. I know its not supposed to be QDR, but read the GDDR5 whitepaper by Qimonda: http://www.qimonda-news.com/download...whitepaper.pdf

GDDR5 has a lot of differences so it might not be properly detected by GPU-Z anyways. That might also be why Vantage crapped out and couldn't give a proper score since it might not be detecting the card properly.

However those test results are ridiculous for the card... if it truly performs at that level, then the 4870 might be closer to the GTX260 and 9800GX2 than we thought.
