[电脑] Nvidia官方证实NVLINK SLI可以支持显存共享

Another important change with NVLink SLI is that now each GPU can access the other's memory in a cache-coherent way, which lets them combine framebuffer sizes- something that was not possible with SLI before. The underlying reason is that the old SLI link was used to only transfer the final rendered frames to the master GPU, which would then combine them with its own frame data and then output the combined image on the monitor. In framebuffer-combined mode, each GPU will automatically route memory requests to the correct card no matter which GPU is asking for which chunk of memory.

意思就是以前无论多少张1080TI SLI都是11GB显存,现在2080TI NVLINK SLI显存可以叠加,此外由原来的交替帧渲染方式改为分割帧渲染,兼容性稳定性有明显提升,此外对于深度学习用户收益也不小。但此功能只支持2080/2080TI

牛逼,稳准狠就是形容老黄这种人的
老黄是不会干出让16GB显存的双卡2070去爆菊自家2080TI这种惨剧的咯

给力,就看两张卡能不能被认成一张卡了
深度学习应该可以,玩游戏应该还是要等配置文件更新

传统SLI技术有一个很大缺陷就是不能用TAA,别看TAA糊而且渲染经常有BUG,但他是目前除了SSAA以外唯一可以对半透明、铁丝网毛发树木抗锯齿的抗锯齿技术,古墓暗影不开TAA或者SMAA 2TX简直不能看

开了SLI之后TAA和SMAA 2TX就实效了,想要效果好只能硬上SSAA开2倍渲染
