“ATI’S coming R600 launch is causing fevered speculation and engendering widespread confusion,” Theo Valich reports for The Inquirer.
Valich reports, “We can now reveal to you that the board you have been seeing around the web is actually a specific design which has only one customer right now. The name of that customer is Apple and it will also be available in Crossfire mode. While we have zero doubts that Dell XPS/Dellienware and some other parties will pick it up as well, right now, the nice red cooler design is just Apple’s and Apple’s alone.”
“The current estimate is that the memory will float between 1 and 1.1GHz GDDR-4 memory in DDR mode (2.0-2.2 GHz), while the GPU clock will be set around 800MHz. Some say 826MHz, but we’re not sure how far the Overdrive will go. We’d say not beyond 850 MHz, but that is just my personal opinion,” Valich reports.
Valich reports, “Our sources tell us that the clock bump should be around 10 per cent for the GPU and 14 per cent for the memory, bringing the total clock to 880/2400-2600. It is insane to see a 700M+ 80nm transistor chip run at such a high clock, especially given the limitations the G80 had with sub-700M chip and 90nm process, but this is an industry where anything that can happen will happen.”
“So, the R600XTX has a special OEM/SI design mostly for Apple, the retail versions won’t come with water cooling, but rather advanced vapour chamber technology, and the board has 8/6-pin config but can be used with two 6-pin ones – in which case you’ll lose the Overdrive feature and stay inside a 225W power envelope, just like Nvidia Geforce 8800GTS,” Valich reports.
