[SOLVED] The need for GPU or not in multi core CPUs

[nonag]

With these new CPUs coming out with 12 or 16 cores (like ryzen 9 ), do they still need a GPU for playing games or video editing?

Sorry if that is a naive question, but my understanding is that most software does not take the into account multiple core. So could the additional cores do the job of the GPU?

Gpu: graphics processing unit.

It's basically a miniature pc all in one designed specifically for processing graphics.

The cpu is busy running everything else. You can use the integrated graphics (igpu) that's part of the cpu, but you are talking about a 10:1 or even upto a 100:1 difference in outputs.

Your understanding is flawed. Multiple is more than one. Almost all software used today uses at least 2 threads and as many as 64 threads, depending on the software. Most times the term 'multi-thread' refers to more than 4 threads, which is most newer games, older games that are still around like skyrim and CSGO and LoL use upto @ 4 threads at times.

High core count CPUs have no built-in GPU so an external GPU is always required. It is just a question of "how much" GPU. For "easy" games and video editing a $150 graphics card may be sufficient. First person shooters or 4K gaming, then as much graphics card as you can afford.

In theory, if they would do some changes like creating an output directly from the CPU,they could make the CPU do all the work to display your games,the thing is that even 16 cores will be a joke compared to even an low end GPU,GPUs have thousands of cores that are specialized for making the computations needed for gaming,CPU cores are just not designed for that.
You need like a 128 thread CPU to barely play crysis.

There are a bunch of software renderers for old games and if the game is old enough you can play it pretty well through the CPU.
