I bought Ryzen 3950x 16 cores 32 threads.
The first thing I noticed is some AAA games only utilize 8 cores. When you go multi threaded, it’s a matter of adding more threads which can dynamically selected based on the host hardware. AAA game studios are going the bad practice route.
I understand if they port an algorithm optimized to run on specific hardware as it’s. But, a thread count?
There is only so much that can be multi-threaded, beyond that the overhead just slows things down (and can cause bugs)
More simulation type games (city skylines etc) can multithread more (generally) while your standard shooter has much less that it can do (unless you have AI bots etc)
My point here is the developer managed to split the load evenly between 8 threads. How come they cannot do it for 16?
The keyword, evenly, means all 8 threads are at 100% while other 8 threads are at 1-2%.
You'd need to look at the actual implementation, it's hard to speculate from a tiny amount of data. What game are you referencing?
And as someone who has done multi threaded programming I can tell you that for games it is unlikely that they can just add more cores. You need work that truly can be split up, meaning that each core doesn't needs work to do that doesn't rely on the results from another core
Graphics rendering is easy for this and it's why gpus have a crazy number of cores. But you aren't going to do graphics compute on the cpu
For that number to be 8 though suggests that there's just a "number of workers" variable hard-coded somewhere.
Potentially suggests, but does not prove And I'm quite skeptical they they truly have an example of a game that is running 100% on all 8 cores, high maybe but 100%?
That was long time ago. I believe the game was BF1.
I know it’s hard to speculate but 100% cpu usage for solid 5~7 seconds only for 8 cores cannot be separate workload (single threaded). A spike is understandable tho.
The game play wasn’t impacted to be honest.
