So I replaced a 4GB memory stick in my Thinkpad T420 with an 8GB one bringing the total amount of available ram to 12GB with maximum of 16GB.Even though Lenovo say that the laptop supports only 8 GB of ram total.
As it stands now this 4 year old machine becomes a pretty cost-effective platform for virtualization:
* Intel Core i5-2410M
I just checked, and apparently that model does to all the vt-x stuff, so yes good for VM handling, and even better, apparently with a bios update it can do aes-ni which can be very handy too. Linux microcode handling might also handle the job if no bios upgrade exists.
It's difficult to judge by specs or benchmarks alone. I have 8-core (AMD FX-8320) and 16GB (DDR3-1333), and it's fast when doing nothing, but it just chokes on load. Curiously, there is no lag with mouse under any condition. And, parallel kernel compile (make -j8) is in the ballpark. So, I don't know what's going on. All I can say is, I'm going with Intel on next machine. -- William
