We are planning to use sage for a calculus course,and got some money to buy a dedicated computer. There will be around 20 students using it simultaneously, doing mostly simple computations on it.
We have offers for an intel core i5 (4 threads) and a core i7 (8 threads), both with 16 gigs of RAM).
Would the difference in performance be worth the 100 euros of difference in the price?. Or stated in another form: how important is the number of threads of the processor for the performance of a sage server?
