XP is dead as a doornail (since 2014), so is even Win7 nowadays. No more security fixes. Those old cpus (and even modern ones) all have vulnerabilities and various software workarounds, plus microcode updates, which each have different costs (slowdowns) associated with them. How many cores does the 2007 machine have? AMD has a 64-core machine nowadays. Hey, I'm no engineer, but newer has more cores, faster single-core (higher IPC), more (faster) RAM, less heat / power consumed, better graphics, and a billion other features (faster bootup??). * https://www.phoronix.com/scan.php?page=news_item&px=2004-CPU-3990X-Plus-FX-9590 Try cross-compiling something on both (preferably "make -j"), and see how long it takes. * https://github.com/andrewwutw/build-djgpp/releases And that's not even talking about speedups like SIMD (you know, AVXes are all the rage nowadays), which older cpus lack. Oh, and VT-X has improved, which makes a big difference, too (e.g. VBox). I'm not saying you can't run older hardware. Just be aware that a lot has changed (and improved), even if sometimes there are regressions. (You could also boot a Linux jump drive on both, and run some tests.) _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
