未来 GPU 将是可换的.. http://www.anandtech.com/video/showdoc.aspx?i=2574 After speaking with several AIBs today, we have some confirmation that Foxconn already has design kits for ATI's R580 socket. Pipe and clock information for R580 is still not firm, so we will not comment on that at this moment. However, your ATI video card will most likely come with a socket flip chip from ATI. Unlike the NVIDIA socket prototype we commented about yesterday, the R580 socket is geared specifically for a PCIe graphics adaptor, rather than a motherboard-housed GPU socket. However even with a dedicated socket, graphic card memory would still need to be soldered onto the board. The narrow tolerances of GPU memory would not allow for a DIMM-like solution. ATI's newest R520 GPU already advertises support for a wide range of memory products, including memory that has not even been announced yet. Vendors tell us R580 is some ways away, so don't expect anything between now and CeBit. However, now that ATI's XBOX 360 project is winding down, expect the company to utilize more resources for R580, Crossfire and the Xpress chipset in the coming weeks. AEGIA might have a run for it's money if ATI has anything to say about it. One AIB commented today that the idea of a dedicated scalar mathematics processor for game physics could already be replicated on ATI's R520 series silicon, although drivers for such a project only exist in R+D departments (the vendor wouldn't let us have them, we tried). The idea of offloading math to a GPU is not a new idea; many projects exist for Linux for this already. However, the indication we had was that ATI could actually do physics calculations on the card with the graphics processing simultaniously -- the bandwidth is already there. AEGIA's physics processor has already been delayed well into Q2 next year. http://www.anandtech.com/video/showdoc.aspx?i=2570 --- 其实某种意味上，这样等於把整张PCB当成一种"GPU DIMM"来买.... 因为显示卡记忆体进展这麽快，已经变成很大的投资了。 其次，我们现在很清楚，NVIDIA和ATI应该都已经做了类似的设计， 比方说NV40/41/42与G70等256bit产品，以及NV43与後续的G72/G73等128bit产品， 各自都是p2p(针脚相容)。 所以其实要做到GPU socket并不是真的很难； 但是要达到这种商业模式应该还会需要一些调整与适应，不过的确是个点子就是了。 反过来想，这样对显示卡厂商也比较好：不论user得如何取得GPU， 重点是同一张PCB的存活时间应该会比较久，现在这种大半只有公板、 纯靠价格竞争的恶劣状况应该会改善很多。 -- 作业系统 Microsoft Windows XP Professional 64bit CPU类型 AMD k8 3000+ MHz 主机板名称 MSI NEO4(白金版) 系统记忆体 创见 1G 双通道 (DDR SDRAM) 旧视讯卡：N社牌==>热情如火，不想用卖掉，拒买热情如火N社卡。 视讯卡 憾讯 ATI X850PRO 256bit 256MBDDR3 --
