Intel Xeon PHI?

Edit: After some runtime tuning by mprime at 2% done the ETA is now 55 days.

After another auto-benchmarking by mprime the ETA is now 47 days (with 4% done)

This is about 66% of the speed of a Radeon VII. Not bad for a cheap low-end chip.

Radeon VII list was $699 new. Xeon Phi systems were considerably higher, ~$5k new as I recall.
The 7210 alone was ~$2036. https://ark.intel.com/content/www/us...z-64-core.html
