alt Hacker NewsBeing mistaken on the CISC vs RISC debate (besides, modern x86 is closer to RISC via micro-ops then old school CISC) is understandable. There is a lot of misinformation out there and myths, plus, it just feels right to consider CISC overly burdened, etc. TLDR: Intel x86_64 is closer to RISC then you likely think and Apple Silicon arm is closer to CISC then you likely think. These lines are blurry and have been for decades, very much for good reason.

Thanks for your prejudice on me without knowing anything about me. In short, I'm a HPC sysadmin and programmer who works in a HPC center, separated from the actual hardware by a couple of floors.
We can discuss how transistors' heat generation doesn't discern about ISAs or being in a DAC or a cutting edge microprocessor, and we can even discuss how implementation of some functional blocks generate heat regardless of the ISA being involved. If you want we can discuss how saturating memory controllers affect pipeline saturation in processors even...
