    "returning to high-end graphics" is kinda stretching the definition of the word "return" as they have never been there.
    Obviously, bad luck has very little to do with BB's failures, problems like overestimating one's ability to develop bug-free solutions or putting all your eggs in one basket ( going with just one EDRAM supplier with no backup available ) are not just bad luck, i'd call it bad management.
    Commonly, good technicians do not make for good businessmen.

    Technically it would be a 'return' becuase they WERE in the high-end segment, and were developing a high-end part, they just never got it out the doors.

    What was XBA (Xtreme Bandwidth Architecture) anyway? I remember that being their piece de resistance, so to speak. What are the modern equivalents used by Nvidia and ATI? Has the PC world lost anything by BB's failure, or were they technologically eclipsed in every way by Nvidia and ATI?

    XBA was an embedded memory architecture that utilized on-chip memory in order to create massive bandwidth across a high bit value bus. XBA is a great technique for generating the bandwidth required for the massive fill rates of current generation video chipsets, but the production of such a chip often proves to cost prohibitive for most manufacturers due to yeild concerns.

    eDRAM has proved to be a very smart way for cost effective GPUs (ATI Flipper, SONY GS). It definitly will be the future for PC GPUs too as soon as the shader race is over.

    IIRC, ATI have stated that they won't go eDRAM until it becomes feasible to put the full framebuffer into the eDRAM, even at high resolutions and with AA. Given 1600x1200x32 resolution and 4x multisampling, we are looking at ~60 Megabytes here. Will take at least another 2-3 years until that becomes feasible.

    Well, Flipper shows that luckily only the back buffers HAVE to be in embedded RAM...

    If ATi went with tile-based rendering (not necessarily deferred TBR) it'd actually be feasible.
