It looks like the Chinese website it168.com has leaked out AMD's internal marketing slides that are under NDA for the ATI Radeon HD 5830 graphics card that comes out later this week according to rumors. Here is your chance to see all the specifications and pictures of the video card before it even launches!

The card, when launched, will become the entry level Radeon HD 5830 graphics card.

The AMD Radeon HD 5830 will have 1GB of GDDR5 memory and looks to be in the $200-$250 price segment. This makes the Radeon HD 5830 extremely affordable.
As you can see the Radeon HD 5830 fits between the Radeon HD 5770 and HD 5850 graphics cards. It has the same number of transistors as the Radeon HD 5850, but fewer stream procesors and have the ROPs. With just 1120 stream processors the Radeon HD 5830 has 22% less stream processors than the Radeon HD 5850, but tries to make up for it with a higher clock frequency on the stream processors that it does have. By running at 800MHz rather than 725MHz it gets a 10.3% performance boost on the remaining stream processors. This means that that the overall compute performance of the Radeon HD 5830 is an impressive 1.79 TFLOPs, which is 14.4% behind the Radeon HD 5850. Not bad looking! The render backend though gets hammered since it has only 16 ROPs rather than the 32 found on the Radeon HD 5850 and Radeon HD 5870. It also has 56 texture units, which is 22% fewer than on the Radeon HD 5850. The end results here is that the pixel fillrate and z/stencil performance is nearly half that of the Radeon HD 5850.... Very interesting. We basically have a Radeon HD 5850 that had some faulty locations in chip that were disabled, the engine clock was then overclocked to increase the compute performance and a new card is being launched. This is good in the sense that the core ASIC isn't going to waste, but the card does have one downfall... It has higher power consumption than the Radeon HD 5850 according to this leaked slide. That is likely due to the fact that the Radeon HD 5830 has increased core voltages that are needed to reach the higher core clock speeds. The end result is a card that is cheaper and less powerfull than the Radeon HD 5850, but one that also uses more power.

Here it looks the card has a max power draw of 175W at load and 25W at idle and it has the ability to support six monitors.
If the leaked mareketing slides were not enough they also posted up pictures from ATI's FTP for NDA press on several of the retail cards that will be ready at the launch:

I'm shocked they didn't post the performance numbers as that is all they are missing for the most part.
