The inquirer learned the upcoming R600 GPU from ATI may be the biggest graphics chip of all time:
It won’t be cold either. Indeed, it might be the hottest chip ever, but we were informed that it might be the fastest chip as well.
Even though many have assumed the chip will be the same as the one ATI supplies for the Xbox 360, it won’t be. It will share a similar design but won’t have the integrated memory on die.
It might have as many as sixty four Shader units that would easily make it much more powerful than the Xbox 360 graphics. There may be a lot of 'mights', but there can be no doubt that it will end up faster than the current generation of consoles. And, don’t forget that it can, and will, support the upcoming DDR4-four memory format.
The launch date isn't official yet but it will likely be towards the end of the year.
