Run your favorite games, see if one part maxes out while the other part remains underutilized. If yes, the maxed out part is your bottleneck.

Did you already built it? If not then would go with Ryzen 5 5600X and 3200 MHz CL 16 or 3600 MHz CL 16 RAM.
RX 6700 XT would be better idea over RX 5700 XT too.

So to answer this formally, let's define what a bottleneck is.

A bottleneck is "the part in the system that is preventing more than current performance at a given time". I tried to be careful with my word choice because it matters.

Technically, every PC has a bottleneck, and at every moment. We don't have instantaneous, infinite performance on hand. Something is always the slowest part of the chain.

There's two distinctions that need to be understood.

The "slowest part" isn't a singular thing. The way things can load a PC aren't constant. They are very variable and dynamic, actually. So what is the bottleneck in one moment might not be the bottleneck seconds (or microseconds) later.

Additionally, it... doesn't matter. This is a technical distinction only. Bottlenecks always happen, but do they matter? No, not themselves anyway. What matters is performance. If performance is meeting your desired level, then it's a non-issue. If performance isn't meeting your desired level, then it's worth investigating how your workflow loads your PC to try and identify what is most the limitation in "preventing more than current performance" and choose it as the part to upgrade. Sometimes you need to upgrade multiple to achieve this.

Now when most people, gamers especially, fuss over "bottlenecks", what they're probably more referring to is "is my system woefully imbalanced for games". Even THAT is hard to address because even games vary, but the rule of thumb is that the load is typically more constant to be reliant on the GPU, and if it's not, a CPU bottleneck is seen as bad.

It's a good thing there are ways to tune games for a given system and desired performance levels with settings, so it's even more of a thing you shouldn't worry about.

After all that, if you want my opinion on the hardware pairing in general, I think it's probably fine. I can nitpick on the CPU and say you have an upgrade option to Zen 3 (the 5600 non-X is a fantastic value right now) and that Zen 2 and newer REALLY want 3,600 MHz or maybe at least 3,200 MHz but your current RAM is really slowing the Infinity Fabric down. But do these matter to you? Maybe, maybe not. It will depend on what you're asking of it. There's definitely use cases where that hardware won't suffice. But there's plenty where it will. So the question is, are you happy with it? If not, seek out why and try and figure out what to upgrade. Despite the off-hand factors I saw and mentioned about the CPU and RAM, maybe you want to do something that you want more performance for and it's the GPU that needs upgraded instead.

There is no "objectively right" balance. Balance it based on YOUR needs.

Just downgrade your gpu, problem solved

so the only non-balanced part would be AMD Radeon RX 6800, i wanted to know more about this fact that game`s cpu/ram recruitment will increase as well as gpu or not and this is a performance per dollar list in my region since many parts are not available or some parts are sold so cheap or as retail stock.

[_I_]

there is always a bottleneck

most of the time its cpu or gpu
but can also be game engine or vsync/refresh cap

its difficult to tell cpu bottleneck when the cpu has more cores/threads than the game can/does use
most games heavily rely on a single thread, which is why core performance beats core clock or core count with games

easier to tell by looking at gpu usage, if vsync is off and its below the max game limit, and gpu is not at 90%+ then its most likely the cpu


2400-2600 ram is kinda slow, esp with higher timings, cl16 should be on 3200
ryzen cpus do like fast ram 3000+ with lower timings cl15
aim for speed / cl <200 for good performing ram

3200 / 16 = 200
3000 / 15 = 200
kits are cheap

2666 / 16 = 167, very poor
