    Default AMD Releases The Radeon HD 5970 2GB

    Phoronix: AMD Releases The Radeon HD 5970 2GB

    Today AMD finally lifted the lid on Hemlock, their new ultra high-end dual-GPU graphics card that is being marketed as the Radeon HD 5970 (similar to the Radeon HD 4870 X2 but now for the Evergreen GPU family). The Radeon HD 5970 has 3200 stream processors (1600 per Cypress GPU), a combined 2GB of GDDR5 video memory, and AMD Eyefinity support for driving three displays simultaneously...

    Wow the US price of $599.99 from amazon.com seems seriously good value. The UK amazon price of 528.67 ($889.011 at current exchange rates) http://www.amazon.co.uk/Sapphire-HD5...8554603&sr=8-1 seems not to be.

    The big question is if it offers anything more then a single GPU card, or is it going to be the same old song and dance that you can only use 1 GPU under linux leaviing it no better then a extremely overpriced 5870.

    Monster card for Microsoft Windows, but just an expensive paperweight for Linux.

    Go go AMD

    Maybe somebody can put some ligth on that strange thing: it is said that the open source driver does not work with digital outputs... but aren't digital outputs managed with the infamous ATOM bios where video mode programming is done the same way on any ATOM bios board?
    If breakage there is, is this related to the new eye infinity engine?

    Modesetting is not done the same way on every ATOM board. ATOM just provides an abstraction from the hardware; the ATOM setup changes as the hardware evolves. The crtc and analog ATOM tables are pretty similar to older generations, however the digital ATOM tables have changed due to the new display hardware.

    2GB of VRAM sounds nice, GTA IV would be happy. $600 is awful lot of money .

    Yep, that's the fundamental difference between AtomBIOS and conventional video BIOS -- conventional VBIOS force the API to a "lowest common denominator", AtomBIOS evolves along with major changes in the hardware.

    If we only used the VESA BIOS calls then digital outputs would be working, but there's already a vesa driver for that with all of the limitations that go along with it.

    Eyefinity is a pretty drastic change from previous display controllers, so there's a learning curve associated with the initial debug.

    Default new table?

    So it's not the ATOM functions that have changed but just the digital output table format! It's "just a matter" of writting a proper table parser, but in the end the same ATOM functions get called?
    BTW, is the eye infinity engine transparently managed througth the ATOM bios? Is it the eye infinity which pushed the new table format? That would explain much since configuring the transmitters/scalers-scanners to output one framebuffer on many displays implies a new logic.
