I haven't actually tried that specific comparison, but form my experience a Pi tends to be a tiny bit faster in pure CPU performance than qemu on Intel. (But not much.) The RPi3 is also a quad core, so that is similar. YMMV may vary depending on the precise workload though. That said: - It has only 1 GiB of RAM. That might be a problem. - It doesn't have as much cache as an Intel Core CPU, so if you have workloads that require a lot of memory access, that'll probably offset any small advantages in pure CPU performance. - I/O is quite slow. If you compile large things my guess is that just because of I/O it'll take longer on the Pi than with qemu. OTOH, it's cheap, so even if it's not the right thing in the end you're not going to waste a ton of money. You could also first buy just the board and power supply and only buy a case and other accessories once you've verified that it's sufficient for your use case. Then again, there are also other ARM boards in a similar price range out there, which might suit your use case better. But I really am not an expert here, I've just played around with the Pi a bit in the past... Regards, Christian
