Are 2 1080TI better than a single 2080Ti?
- ydau 8y agoYes. 1080 Ti do not scale linearly, but in most of the benchmarks I’ve seen, two 1080 Ti are at least 1.75x faster than one when doing multi-GPU training. 1.75 / 1.36 (speed up of 2080 Ti over a single 1080 Ti) = 1.28. So expect 2x 1080 Ti to be about 30% faster. You can see how multi-GPU training works with Titan V benchmarks in the link below. 1080 Ti have similar scaling profile. https://deeptalk.lambdalabs.com/t/benchmarking-the-titan-v-volta-gpu-with-tensorflow/108 https://deeptalk.lambdalabs.com/t/benchmarking-the-titan-v-v...
