Run a profiler on your code sometime and see how many branches it reports taking. You can easily get millions of branches per second, so 1% events happen hundreds of thousands of times. See for example this quick investigation and look at

Those 1-4 bytes are sitting in a register the entire time and thus basically free to read as often as you want, though. An actual sampled profile showing the two approaches would be interesting. Naively it seems like it's just because

Graphics driver crashes don't result in BSODs anymore. Microsoft fixed that in... Windows 7? Vista? They just trigger a black flash of the screen for a few seconds and then everything is back up as it was - including active GPU context

Culture definitely hurts it a lot. It seems like any question involving Java and anything performance related is "you don't, you're stupid, the JIT fixes everything, never measure, never benchmark, premature optimization is

The gap between Java and [C++,Rust,Obj-C,Zig?,D?] is approximately equivalent to 5-8 years of CPU hardware improvements these days. Software engineer time is still often the primary cost metric, but Java didn't ever get actually fast

C is the worst at naming length since everything is in the global namespace unless you're working on a teeny tiny project. So everything gets clunky prefixes to use as pseudo-namespaces or overly descriptive name to avoid conflicts. Lo

The horror stories are always about people seeing how cheap used 7 series or similar are and not realizing that repair costs are still going to be reflective of the MSRP, not the now drastically depreciated used price.

I think the price has stealthily increased as the required dressings got more demanding. Like the initial pi could be powered by any random phone charger you had laying around. But the new ones are a lot more picky and demanding. The new on

Sure, which is why you see other midrange APUs use >128-bit buses, eg PS4 & PS5 are both 256-bit buses w/ GDDR. Similarly, ultra high end APUs like the Xeon Max are doing on-package HBM for truly monstrous memory bandwidth numbe
