RTX 4080性能曝光:恐怖90T算力、2.5倍于RTX 3090

眼看RTX 30系显卡的拼图已经基本完整,NVIDIA是该好好准备RTX 40系了。日前,爆料好手Greymon55在社交平台给出消息称,lovelace的频率能到2.5GHz,这样单精度浮点可摸到90T,而RTX 3090 Ti不过40T。

关于浮点性能这个话题,列几个数字大家参考下:

PS5:10.28T

Xbox Series X:12.15T

RTX 2080 Ti:13.45T

RTX 3090:35.58T

从他的话语分析,说的应该是Ada Lovelace大核心,换算出相较于RTX 3090的增幅达到152%、较RTX 3090 Ti的增幅达到125%。

此前,Greymon55也有类似说法,AD102大核在1.8GHz下FP32性能约66.5T,按照惯例AD102预计会用在RTX 4080及以上显卡上,如果这里的2.5GHz/90T说的是RTX 4080,那就太恐怖了。

当然,浮点性能的推算只是一方面,毕竟RTX 3090 Ti因为一些原因并未正式发布,频率设定一直是个谜。

可能正是因为暴力的性能增幅,才有说法RTX 40系旗舰SKU的功耗要上到450/500W+。
