Does CPU matter when crunching with GPU?
#1 Does CPU matter when crunching with GPU?
As in the subject, guys.
I'm testing GTX 660 2GB along with i3-2100 at the moment and was wondering if CPU would be way too weak and bottleneck GPU?

very much depends on project, I'd say. No real problem on Collatz, but Moo could suffer
I think this is fool-proof but could you just try it for me please? • There are 10 types of people in the world; those who understand binary, and those who don’t

Right now I am running Collatz and the estimated finish time will be around 1h30min. I didn't optimize the app though.
Speaking of MooWrapper I planned to hit 1 million and focus on other projects, mainly Milkyway and Einstein. If things go well next year I might get something better than this ancient GPU.

nVidia are very good on Collatz, Moo, Primegrid but less so on Milkyway and Einstein where AMD do better. Life is never easy, huh !Hal Bregg wrote: ↑Sat Dec 28, 2019 3:57 pm Right now I am running Collatz and the estimated finish time will be around 1h30min. I didn't optimize the app though.

No, it's not. The only solution is to have another rig with AMD or swapping cards every few weeks.davidBAM wrote: ↑Sat Dec 28, 2019 4:06 pmnVidia are very good on Collatz, Moo, Primegrid but less so on Milkyway and Einstein where AMD do better.

they are not computers - headless workstation with wireless LAN is a room heater
