Is PC Builds Bottleneck Calculator accurate? Could an RTX 4080 go with Ryzen 7700X?

[Delicieuxz]

According to the bottleneck calculator, no way, showing up to a 37.6% CPU bottleneck in processor-intensive tasks, at 1440p.

I've got an unopened 7700X CPU for my X670E motherboard, 64GB RAM, and RTX 3080 system build, which will run with a 1440p monitor. My outlook is to, over the next few years, upgrade the monitor to a good 32" 4K display, upgrade the GPU to probably something better than an RTX 4080, and upgrade the CPU at the tail end of AM5's life-cycle to something high-end.

 

Ideally, I'd stagger the upgrades, because that's a lot more palatable than buying a high-end monitor, GPU, and CPU all at once. Yet, if I buy a 4K monitor, my current setup might be struggling right away in newer games until I also get a new GPU. But if I buy an RTX 4080 TI, or an RTX 5070 or 5080, will I see almost no gaming-performance gain until I also get a much better CPU?

 

I could return the 7700X and wait for the 7800X3D... but then, when its FPS increase over a 5800X3D is 15 - 30% at 1080p, will the percentage of FPS increase be so minimal at 4K that it won't do a lot to solve the 7700X CPU bottleneck issue, anyway?

 

 

The bottleneck calculator says that a 7700X will already be bottlenecking an RTX 3080 by 2.4% in processor-intensive tasks. While in GPU-intensive tasks, the GPU will be bottlenecking the CPU by 1.6%. So, this CPU and GPU combo is a perfect fit for each other. But, if the calculator is accurate, neither gives headroom to upgrade the other component independently.

Those calculators are generally meaningless, the 7700X is a solid chip for even a 4090, let alone a 3080. Just ignore that number, it's complete BS

"Generally" is a very generous term for "always".

Most of your issue is going to be on GPU regardless, 4K is still GPU bound even in 2023.

That's what I was hoping. Thanks.

That calculator (and many similar others) was made by ignorant people who do not understand a thing about CPU<->GPU bottlenecks and bottlenecking.

Made just to attract traffic to the site and get them some revenue (cash from advertisement).

Funny calculator.
