Nvidia終於讓Intel X58明媒正娶原生SLI
《 轉載來源:癮科技 》
[撰文:icebin]
在此之前,X58等Intel等高端平台如果要支援SLI,則必須通過一顆nForce200的外 置晶片才能實現,現在:Intel X58平台即使不搭載nForce 200橋接晶片也能原生支援SLI!
通過認證的X58主機板可以支援雙通道x16 x16或三通道x16 x8 x8模式的SLI,使用兩塊雙晶片的 GeForce 9800 GX2也行,三塊顯示卡加一塊物理卡也可以,但受限於當前的驅動程式,還無法向AMD CrossFireX那樣同時使用四塊顯示卡。
Intel X58 主機板授權並非自動獲得,主機板及 PC 業者們需要把產品交給 Santa Clara Certifcation Lab 進行認證,成功通過認證的產品將會獲得授權密碼 (Approval Key) ,讓主機板業者放置於 Intel X58 主機板的 System BIOS 上,驅動程式將會確認 System BIOS 內的授權密鑰及 Chipset 的 Device ID ,決定是否提供 SLI 支援。至於SLI授權是否會擴展到其他平台,Peterson補充說,目前Nvidia只打算允許X58平台和自己的nForce晶片組產品使用SLI多 卡互連技術,現在Nvidia還不會考慮在此方面支持其他品牌或型號的晶片片組。《 原文來源:PC Perspective
》Bombshell of NVISION08 SLI goes native on Intel X58
Saving the Biggest News for LastNVIDIA has always been known for having a strong marketing team and the relative success of NVIDIA%26#39;s first hosted trade show is evidence of that.%26nbsp; Apparently though the NVIDIA team was scrambling to come off the show with some hard news that would excite the core gamers and in a last minute move to save the opportunity of having hundreds of press at your disposal, NVIDIA dropped a bomb shell of a news story on us at the 11th hour. %26nbsp; We have known for some time now that NVIDIA would not be producing a chipset for Bloomfield, Intel%26#39;s consumer products based around the Nehalem architecture we detailed just this week.%26nbsp; This of course raised the question of where SLI would fit into what will obviously become the new de facto standard for high end gaming systems.%26nbsp; NVIDIA answered with the announcement they would allow the nForce 200 chip to be implemented by board manufacturers for SLI support in a similar fashion to how the original Intel Skulltrail boards were released.%26nbsp; From out talks with board manufacturers though, not many were planning on implementing the chip due to heat issues, board layout and design problems and it just in general being another headache to worry about with a new product launch.%26nbsp; NVIDIA took that feedback to heart it would seem and came up with this: NVIDIA is going to allow the Intel X58 chipset to natively support SLI graphics configurations. Let me let that sink in. %26nbsp; No need for an nForce 200, no need for any special logic of any kind, no need for an NVIDIA product but the graphics cards themselves.%26nbsp; Obviously this is GREAT news for the gamer - now we can finally get high quality motherboards that are reasonably priced and will run both NVIDIA SLI and AMD CrossFire GPU configurations.%26nbsp; We are very excited about the idea of unifying our platform selections for the hardware leaderboard, for using a single motherboard for all our graphics card testing and just excited about what it means for high-end PC gaming in the big picture. %26nbsp; We should note that this SLI licensing arrangement will ONLY affect upcoming X58 motherboards - this will not be retroactive to motherboards using X48, X38 or any other chipset.%26nbsp; Why?%26nbsp; Because NVIDIA already offers SLI solutions for those processors and decided they wanted to maintain the control on that platform.%26nbsp; The driver that supports SLI on X58 chipset motherboards that meet the certified criteria will be available in time for the Bloomfield/Nehalem processor launch in late fall / early winter.%26nbsp; Expect to see reviews of the new Intel CPU using SLI technology as well. But...it raised some interesting issues that needed to be addressed including the licensing of the SLI technology, the previously talked about %26quot;technical requirements%26quot; that required NVIDIA logic and much more.%26nbsp; Read below for my thoughts. %26nbsp; What PCI Express Configurations are Supported I am happy to report that with the Intel X58 chipset NVIDIA will supporting basically the entire gamut of PCIe division options.%26nbsp; Motherboards with as few as two PCIe x16 slots and as many as four PCIe x16 slots will be able to run SLI.%26nbsp; Interestingly, though NVIDIA doesn%26#39;t have a four-card SLI option today, they are supporting 3-Way SLI a four graphics card for PhysX in addition to standard 3-Way SLI, 2-Way SLI and Quad SLI with two dual-GPU graphics boards.
