RTX 2080 - 10 TFLOPS, 448 GB/s RTX 3080 - ~30 TFLOPS, 760 GB/s So for most things compute you'd expect anywhere from 70 % to 200 % performance increase. Note the significant increase in operational intensity in this generation, to about 160 FLOps per Float Load/Store (up from ~90). The fact that we're not seeing 200 % increase more widely can point at things like this being a problem for existing applications (so RTX 3080 is _even more_ memory constrained as previous cards [1]), and perhaps also some applications struggling feeding enough work items / scheduling issues in general. [1] Alternative view: Even more operations you can do for free when you have to process a given buffer anyway!

>~30 TFLOPS Jesus.

  The VRAM bandwidth is still under a terabyte per second so you still need a fair bit of data intensity to actually approach that. It's still amazing. I think I know what Jesus In A Leather Jacket has planned for next year though.

  The November 2001 top500 supercomputer had 7.2 TFL0PS: https://www.top500.org/lists/top500/2001/11/ https://www.top500.org/lists/top500/2001/11/ It's fun to compare it with the historical top500 list: https://www.top500.org/statistics/perfdevel/ https://www.top500.org/statistics/perfdevel/

    I wonder how much that machine cost...
