要不然7900xtx 24g光栅化为啥打不过5080?
5080要是12GB肯定不够用,24GB则有点多余
16GB升级24GB总体性能不会有明显差别

首先都买5080了,肯定要开路径吧,那不好意思16G必爆。
难道没人告诉你路径追踪光线重构和帧生成都吃显存吗?

还有个瓶颈,就是功耗,5080最强的bios功耗才纸面450w(4k全最高游戏实战一般也就400w左右),反观4090和5090常规最强bios游戏实战也能到550~600w,这就拉开差距了,我都不谈俩90的双16pin卡专用的1000w和2000w魔改bios了[s:pst:偷笑3]

所以8000买16g很骄傲吗?显存多烫手是吧[s:a2:你看看你]

你买个显卡是用的还是看数值的

既然如此,那5080super按你说的就没用了,显存带宽不变,反正瓶颈不在容量上[s:ac:哭笑]虽然我觉得5070tisuper的24G确实没啥用。
