    Default The introduction of 512MiB consumer graphics hardware

    It wonít be long before manufactures start singing that a 512Mb graphics card is the best thing since slice bread. HEXUS looks at ATIís X800 XL with 512Megs (reference board) and Beyond3D looks at the Sapphire Hybrid Radeon X800 XL 512MB, which is essentially the same board. Head on over and check out the numbers

    "As we've seen time and time again with low-end boards that pack the memory on, but which use asthmatic memory bus widths to talk to it, there's little point in giving a bandwidth-starved graphics chip more memory which it can't realistically use to accelerate 3D performance. Here, on-card caching schemes work best to make the most of what they've got, especially if you want to use the board for something other than 3D graphics and games. While you might not have the bandwidth on the board to feed the GPU very well (often less than 5GiB/sec on 64-bit memory bus low-end hardware) to render complex scenes, that doesn't mean you have to leave blocks of memory empty. You still want to upload data to the board even if it won't be processed for a few frames. Speculative preloading on 512MiB low-end hardware would make some sense, if the driver is able."

    Boo...barely a need for 256MB at this point. You'd be better off buying a X850 for the same price...

    been some efforts to use video-card memory as system ram. Apparently they've figured out a way to do it, at least at a rudimentary level (where, say, 384mb of the 512mb could be used as a "fast swap" device).

    But all in all, most people wouldn't want to bother with it all. But it would still be interesting to see it in action

    That would be pretty cool, but for the price of that 512MB card, I'd rather just buy a new RAM DIMM .

    Whatís surprising is Doom 3 on ultra settings, which was supposed to be for 512Mb cards, there is little difference from the standard 256Mb XL. At the opening price point I would go with a 6800 GT PCI Express and buy another one later down the line.

    A little more recently, ATI came up with "HyperMemory" which is a move in the opposite direction. They want to use system RAM as GPU RAM. There hasn't been any motherboard support for it, though, that I know of.

    Both ATI and NVIDIA have similar techniques.
