Rumor: Radeon HD 5800 in September

To be very cheap and have 1600SPs.

This is the breakdown of the features of the upcoming Radeon HD 5870:

• 1600 shader processors
• 384bit (some point to 256bit) memory interface
• HD 5870 will cost $299
• Release on September 22nd

Most of these rumors will probably turn out fake but the release date should be around that time. These screenshots are most likely fake than not, since AMD typically only manufactures black PCB cards for the high-end series, of which the Radeon HD 4870X2 was the last one - the other ones are red.
This also was rumored to be the RV840 chip, or the Radeon HD 5770 card. I would be surprised if AMD did already have those cards running so soon - the RV870 will come a lot sooner.

The 384-bit memory interface would be a requirement to "open a can of whoop ass" on Nvidia, but the $299 price would mean a 256bit interface with some higher speed GDDR5, which would deliver 160GB/s, or around what the GeForce GTX 285 can do - which would still be great for this price point.
