Now that ATI has established a 40nm manufacturing process with its Radeon HD 4770, it was only a matter of time before the rumour mill began to churn out details of other upcoming 40nm parts.

Today, the attention's turning to potential RV870-based parts. According to German site hardware-infos.com, ATI's RV770 successor will arrive as soon as July '09 in the form of the Radeon HD 5870 and the dual-GPU Radeon HD 5870 X2.

It is, of course, entirely speculation at this moment in time. However, should the report be believed, the products will line up with the following specifications:

*rumoured product and specification

The numbers are anything but confirmed, but we could be looking at 4,560 GFLOPS from the Radeon HD 5870 X2 - almost double that of the Radeon HD 4870 X2.

was hopin to hear about something more groundbreaking than just more of the same really, even if it is twice as fast.

groundbreaking how? first dx11 parts and a huge chunk faster than a 4870x2 sounds tasty tasty to me

It's twice as fast, full DX11 capable, uses the new 40nm process.. how much more groundbreaking do you want?

Er, what ground do you want broken? Flashing lights? Tea-making facilities?

Its all rumours but good to know a rough idea of dates and specs and that ATI is on the war path and keeping the heat on Nvidia.
