Is my CPU really a bottleneck?

willhub · 17 Apr 2018 at 13:18

I came across the bottlenecker website, it reckons my 4820K CPU is an 11% bottleneck to my GTX1080, considering it's at 4.3GHz do you think this is the case?

Interestingly enough I put in the combinations of some laptops on sale and with GTX1070 and a 7700HQ it reckoned that was a bottleneck but is that really the case?

What resolution do you play at?

1440P on my PC, Laptops are 1080p so take that res on a laptop into account and sometimes TV (4K)

For gaming at 1440p I would say no, as you become more GPU-bound at higher resolutions. The CPU matters less.

For 4k, not at all. Very much GPU-bound at the point, CPU matters even less.

I wouldn't really call it a "bottleneck", rather in some cases you could achieve an 11% performance increase with a more modern CPU, but then isn't that always the case? And believe me, other than in benchmarks, you aren't going to notice 11%. The 4820K is a perfectly good CPU. Of course you can get better, but do you really want to spend tons of money on a relatively small increase in performance? Only you can answer that!!

That website suggests my graphics bottlenecks my CPU by 84% lol. I don't game though and it's only plugged in as a secondary (to the inbuilt UHD630) for hardware acceleration of transcoding in Plex and Emby.

Curiously, if I select my graphics as the 8700k's onboard UHD630 and omit the 1050Ti, suddenly it swaps around and it reckons the CPU is bottlenecking its own graphics massively. *shrug*

It says my GPU is too weak.
I KNOW! How about a website that tells me how to afford a 1080ti ??

That website is pretty ridiculous. It completely depends on the game, the resolution, the desired FPS even.

And that's assuming you're gaming! Complete misinformation to produce a website like that IMO. Irresponsible.

Seemed accurate for mine, it approves of my upgrade strategy.
