How to identify bottlenecks

[ce.eeries15]

Hello everyone,

I searched on carb for a similar thread but did not find anything.

I want to know how do I calculate bottlenecks before purchasing a new cpu/gpu. I tried using a bottleneck calculator, and it said the i79700 will bottleneck a 3070, but how do I confirm if this is true or not without buying and trying?

Does anyone not know of a formula of calculating it beforehand?

Thanks in advance

Pro tip: Search google before you search Carbonite
I'm sure you can find something way more accurate if this site is at all accurate to begin with.

There's no specific formula, but check some reviews of the various products and you'll be able to see.

What resolution are you planning on running at? 1080p will be more CPU bound compared to 1440p where the bottleneck will be more on the GPU.

Here are some benchmarks from last year to give you some idea of what's what.

The easy way, read hardware reviews and compare the tiering of different hardware combinations.

The proper way, study a compsci degree to understand how the different computational power of each microprocessor, hardware, and firmware is linked together and where such inefficiencies result in bottlenecks. I vaguely remember a uni tut about calculating the theoretical maximum throughput of printing some characters to a printer for some random cpu of a given frequency, was a real headache and pain in the ass to get the final result of X characters per line per second in bits per second.

What are you upgrading from?
Just get the new gpu and enjoy the extra fps while saving up for the cpu upgrade.

There is no such thing as a "bottleneck calculator". Most likely never will be (at least not conceivably accurate)

Thanks for the feedback bookies, much appreciated
