i7 8700 bottleneck RTX 3080 @ 4k60?

[kevinj93]

I'm planning on upgrading my RTX 2070 super and getting the RTX 3080 this week and I was wondering if my 8th gen intel i7 8700 (non k) will be a bottleneck @ 4k60? CPU is running at 4.6 Ghz with a BCLK overclock. Not planning a CPU/Mobo upgrade anytime soon.

 

RAM: 16GB (2x8GB) 3Ghz DDR4 XMP On

 

Your opinions?

We don't know yet for sure but according to JayzTwoCents.. it is. That there is a noticeable amount of FPS difference with the 8000 and below. And frankly, Intel chips from a year ago or more is kinda weak nowadays. Yes it can spit out a little bit more frames in games but that's about it. So not surprised at all. I guess we'll wait and see for the benchmarks.

This may seem a bit obvious, but waiting until PCIe Gen 4 tests are out for the 3080, might be a good course of action. If it winds up making a substantial difference, making sure you have a PCIe Gen 4 ready mobo and CPU might be a good way of knowing whether or not your CPU will bottle neck the 3080. B550 and Z490 mobos, along with the corresponding CPUs might be a big part of the equation in the future when it comes to the 30 series.

there are very few* games that dip below 60fps on 4k with a 3080, and when it does, it's a 2-4% (1-2fps) bottleenck compared to a 10900k.

 

The pcie3.0 bottleneck tests are already out, it's also 1-2%, but zen 2 is naturally slower than coffee lake so gotta wait for zen 3 to worry about that if at all.

So basically higher resolutions = more GPU bound therefore less CPU bottleneck since the CPU has to work less because GPU is being maxed out.

I just happened to read techpowerup's review that used the 9900k vs 10900k, although there are some differences at 1080p but the charts are showing very similar results at 4k. I don't think the 8700 is much slower than a 9900k (maybe 10-15% difference at best but that's it)

 

I don't really mind getting very high framerates anyways (300fps+)... Most of the time up to 100-120fps would suffice. 

 

Only time I'll be upgrading is when Intel releases their PCI-E 4.0 motherboards ... Never been a fan of AMD that's why I have no plans of upgrading nowadays...

Hardware Unboxed did some benchmarks on 4.0 vs 3.0 and it doesn't make much difference. But as the drivers mature it might.

it's way less than 10-15%, it's barely 10% with the 3600 in the most extreme scenarios, maybe the gap widens with the ring bus cranked up, but it's not 15%.
