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.

no Nvidia has better idle consumption than ATI but when under full load ATI is better performance per wattQuote

Horse manure....

Although this doesnt have the VERY latest cards from both sides it does cover 4670-4850 for example (ie mainstream) and Nvidia is POOR on power consumption.

There was just so long I could go letting this inaccuracy slide... :O_o1:Quote

I admit overall the ATI cards seem to have overall better idle power consumption than the Nvidia 'equivalents' but that chart doesnt take in the above quote at all and the main cards which are compared (as they have extremely similar performance) are 4870 and GTX260 where my statement holds true.Quote

You're not talking about the performance sector here, but that's what we're interested in, and it's a very different story purely because of the DDR5 in the 4870 upwards which can't be put in a low voltage idle state. Therefore ATI cards have high idle power compared to the nVidia's, but a lower 100% load draw.Quote
