Single core perf has become more than 50% better on desktop since Sandy Bridge, and it should be even more than that in TDP constrained environments like laptops because of reduced power consumption, which is partly why we now have quad core / eight thread ultrabooks. The total performance of such a device would almost certainly be more than double an X220 in a slimmer package.
Maybe 4x is your cut-off point for where it's worth it to upgrade?
- michaelmrose 8y agoThere is noticeable on a benchmark and noticeable in actual use. In actual use newer machines don't seem to come with much improvement in performance for a lot of tasks. For me my limited supply of money is the primary constraint. I'll probably upgrade when my machine stops working.
- ealhad 8y agoEven when not having monetary constraints, it's probably better for everybody to upgrade only when needed :)
