要酸就酸吧 今天的GTX680對上7970 不就是6950對上560ti 同樣是同價位 前者比後者低耗、高能 消費者只用選最符合自己的產品 而不是馬上就酸另一個陣營 ![]() 甚至是還有把500美元當成中階產品 還不如等nvidia把200美元的產品拿出來再說吧 主要的消費群關心的是這一塊 |

呃!那個多3倍的Unit並不是以前純CUDA單元哦! 這樣您有稍稍釋懷嗎? ![]() 如果Nv放生0penCL改變CUDA架構是有機會,不過目前還沒有動靜。 至於那些轉檔程式老實說無法發揮CUDA的完全效能,和純科學運算差距很大 在轉檔上的效能進步來自軟体架構改進會多一些…

WHQL-Certified GTX 680 Drivers Limit Sandy Bridge-E To PCI-E 2.0 Speeds
WHQL-Certified GTX 680 Drivers Limit Sandy Bridge-E To PCI-E 2.0 Speeds Posted 03/23/2012 at 10:34am | by Brad Chacos If you've dropped the dough on a spiffy new enthusiast-level Sandy Bridge-E processor, you may decide to drop a corresponding level of dough on a spiffy new enthusiast-level Nvidia HTX 680 graphics card. (If so, we salute your Maximum-ness.) There's just one little caveat you should be aware of, however; Nvidia's initial WHQL drivers for the GTX 680 nerfs data transfer levels to slower PCI-E 2.0 speeds, rather than the blazing fast enthusiast-level PCI-E 3.0 x16 speeds the X79 chipset is capable of. Hopefully it's just a short-term bump in the road due to software validation issues rather than a long-term hassle. Nvidia owns up to the slowed speeds on its specification page for the graphics card: GeForce GTX 680 supports PCI Express 3.0. The Intel X79/SNB-E PCI Express 2.0 platform is only currently supported up to 5GT/s (PCIE 2.0) bus speeds even though some motherboard manufacturers have enabled higher 8GT/s speeds. There is some good news, however: TechPowerUp reports that the pre-launch drivers shipped on the disc that comes with the GTX 680 enable PCI-E 3.0 on compatible Sandy Bridge-E systems. Basically, if you're a SB-E owner who feels the need for that extra data transfer speed, you can stick with the included pre-launch drivers for now and hold off on any new drivers updates until Nvidia comes up with a fix. |

我知道不同世代的CUDA數量不能對等比較 我的意思是,CUDA數量已經增加為3倍 "假如"實際上還無法勝過前代僅有1/3數量的GTX580表現(假設來說) 這樣不代表CUDA架構有大改嗎? (對照從G80以來的NV 1D Scalar SP設計來說,是否在SP規模上有所縮解?) 另外,轉檔輸出的比較 純粹是指同一段影片,在9800GTX、GTX280、GTX460上面開啟CUDA加速 輸出所需的時間比較(例如以TMPGEnc最新版來說) 雖然說轉檔程式可能無法發揮CUDA的全部能力,但只改變顯示卡這個變因 應該可以比較出三張卡在某些限制情況下的CUDA效能吧? 此文章於 2012-03-24 01:29 PM 被 Technology 編輯. |
