you clearly haven't played a modern game :P

cpu timings taken care around by developers is 10-15 years out of date. most of them these days dont even know what a dot product is, how to find the distance to a point or a straight line in-between two... and the people they rely on to do this for them make horrendous meals of it.

but yeah, sure, cpu instruction timings matter.

I was about to say. I bailed out of the industry just as the Xbox One/Ps4 was coming in. Even with the 360/Ps3, it was considered wise to try and steer clear of that kind of low level stuff just for ones sanity. When the X1/Ps4 came in, it was completely abandoned, turns out x86 compilers combined with OoO execution just made that kind of tinkering not only nearly pointless but sometime actually hurt performance.

Nowadays,I suspect it is almost entirely in the hands of the compilers, the API's and the base OS to figure out the gritty details.

There are still manual optimizations that can be done (non-temporal writes where appropriate for example), but nothing like the painstaking removal of Load-Hit-Stores and cache control of the 360/PS3 era.

The new chip will be relevant faster. I would bet that bandwidth between certain components is a lot more critical. Or NUNA or bandwidth between cores.

Im surprised that cpu instruction latency is mentioned before other
