AMD Opens SAM Technology to NVIDIA and Intel Final AU + N card、IU + A card can speed up

       AMD在10月份發佈RX 6000系列顯示卡when,還推出了一項新技術名為“智慧訪問顯存”(Smart Access Memory/SAM)科技可以讓銳龍5000與RX 6000顯示卡合體提升效能SAM科技解决了CPU與GPU之間的一個瓶頸問題

       In traditional Windows-based computer systems,Limited by PCIe specification,Only via Base Address Register (BAR) Map 256MB of system memory to GPU memory at a time,This means that the processor can only access 256MB of video memory (VRAM) at a time,This seriously affects the data transfer efficiency between system memory and GPU memory.,Limits system performance。

       AMD just released the latestRadeon RX 6800When a new card in the series,One of the new technologies is called SAM(Smart Access Memory)technology,Allows the CPU to fully access the GPU's display memory,No more data exchange through Windows mapping,但暫時只限於 A 卡配 AU不過 AMD 前日透露正與 NVIDIA 及 Intel 討論期望可以開放 SAM 技術讓不同 CPU不同 GPU 都能使用

       AMD在RDNA 2中加入了的全新Smart Access Memory技術,When users use AMD’s new generation Ryzen 5000 series processor,PCIe Mapping is no longer used,CPU can directly access GPU memory,Completely remove the read and write bottleneck between CPU and GPU。

       Via AMD Smart Access Memory,Datapaths expanded to exploit the full potential of GPU memory,This eliminates performance improvement bottlenecks by leveraging PCI Express bandwidth.,This feature will provide users with a better gaming experience。According to data released by AMD,SAM technology can improve performance by 5-11% on Ryzen 5000+RX 6000 graphics cards,Game performance can be improved by approximately 6%,Especially for games that use a lot of Texture maps,The performance improvement will be more obvious。

       前日AMD副總裁暨Radeon事業群Scott Herkelman透過在SAM技術正與 NVIDIA進行討論讓AMD CPU搭配NVIDIA顯示卡時亦可以使用SAM同時亦向 Intel 提出開放 SAM 技術的意願

       考慮到SAM科技需要顯卡及主機板BIOS的配合才行所以AMDNVIDIA及Intel三方合作是有必要的這樣才能讓玩家自由組合未來很大機會不論任何 CPU 配任何卡都能啟動A卡+IUA卡+AUAU+N卡N卡+I等等而不是局限某個平臺
