  • To your point of how far new zen cores have come, I have a fun story from work. In short, in my specific use case, my 7840HS (8 zen4 laptop cores) was at parity or outperforming a 1950X (16 zen1 desktop cores), in a fully multithreaded task. The workload was essentially a bunch of RISC-V simulators running independently in parallel through a makefile, so the individual tasks benefit greatly from increased IPC. I’m not sure the entire gain in performance comes from IPC, but it’s probably the majority and that is still very impressive.










  • Good teachers can make such a big difference, and it’s almost always in these kinds of unquantifiable, “I just encouraged the student in the way they needed” kinds of ways. This, as much as anything else, is why defunding the education system is so criminal. Stressed-out, underpaid and overworked teachers just won’t have the mental space to do these kinds of things.
