性能到顶的RTX 4090Ti外形曝光 可能跟你想的有点不一样|显卡|rtx|ti|内部空间_网易订阅

今天下半年将要与广大玩家见面的RTX 40系显卡,日前由某爆料达人绘制了RTX 4090Ti和RTX 4090公版样卡的渲染图。

从图片中来看整体造型有些与众不同,简单来说就是三槽甚至三槽半厚的“大胖子”。规格方面最新的爆料称,RTX 4090内建128组SM单元,也就是16384个CUDA,匹配24GB GDDR6X显存(384bit,21Gbps),整卡功耗450W。

不过,完整的AD102核心实际上有144组SM单元,所以RTX 4090 Ti的CUDA上限可以是18432,2GHz下单浮点算力73T,二级缓存加大到96MB。

对比上一代GA102核心,浮点算力的差距几乎可以说是翻番,这也难怪NV要在公版FE上使用这么夸张的内部空间来保证散热了。
