- danans 6y agoNo, because a CPU isn't a consumable resource, like electricity or labor. You should occupy the CPU with all valuable work (for whatever definition of value) but keeping it pegged for no reason makes no sense, and just wastes electricity.

- slaman 6y agoIt's value deprecates over time though, as it's market efficiency drops relative to newer cards. Your return on the opportunity cost is maximized if you can do work closest to the time the card was acquired. If you buy a card and leave it in the box for 10 years you have not 'consumed' the card, but you have wasted a few hundred dollars. From an electricity and financial perspective if you have valuable work to do, your costs are minimized if you do that work closest to the purchase date. This is obvious if you have a significant workload, but maybe not as obvious if you are running CAD. Is the cost of a new card worth the time saved by the new card? Significantly more efficient if you can keep it busy.
- amackera 6y agoIn a way, by not running useful work 100% of the time, you're wasting the resource of time.
- danans 6y agoI would argue that there is a lot less useful work available to run per unit available CPU time than there is time. Otherwise, there would be market for people to sell their spare CPU cycles. The only entities selling CPU cycles are big cloud providers who have much higher utilization in general.
