That has 125 cuda cores, a couple year old 970 has 1600, i love the single board computers and all but its just not powerful enough On Mon, Mar 25, 2019 at 1:44 PM Solar Designer <solar@...nwall.com> wrote: > On Mon, Mar 25, 2019 at 10:58:55AM -0400, Rich Rumble wrote: > > Wondering if a cheap device like this could be used to create a nice > > cracking rig on the cheap? > > > https://www.nvidia.com/en-us/autonomous-machines/embedded-systems/jetson-nano/ > > No. It will be either slow (few boards) or expensive (many boards). > > I am puzzled by the "like Xeon Phi" in the Subject since this device is > dissimilar to Xeon Phi... except in that neither is cost-effective for > our use case compared to typical large(r) gaming GPUs.
