未來 GPU 將是可換的.. 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 --- 其實某種意味上，這樣等於把整張PCB當成一種"GPU DIMM"來買.... 因為顯示卡記憶體進展這麼快，已經變成很大的投資了。其次，我們現在很清楚，NVIDIA和ATI應該都已經做了類似的設計，比方說NV40/41/42與G70等256bit產品，以及NV43與後續的G72/G73等128bit產品，各自都是p2p(針腳相容)。所以其實要做到GPU socket並不是真的很難；但是要達到這種商業模式應該還會需要一些調整與適應，不過的確是個點子就是了。反過來想，這樣對顯示卡廠商也比較好：不論user得如何取得GPU，重點是同一張PCB的存活時間應該會比較久，現在這種大半只有公板、純靠價格競爭的惡劣狀況應該會改善很多。 -- 作業系統 Microsoft Windows XP Professional 64bit CPU類型 AMD k8 3000+ MHz 主機板名稱 MSI NEO4(白金版) 系統記憶體創見 1G 雙通道 (DDR SDRAM) 舊視訊卡：N社牌==>熱情如火，不想用賣掉，拒買熱情如火N社卡。視訊卡憾訊 ATI X850PRO 256bit 256MBDDR3 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 163.21.235.57
