Will i7-7700hq bottleneck 1070?

[game07]

I have waited for intels 7th gen cpus. But Intel didn't actually upgrade anything. A littlebit overclock thats all. So I am still suspicious that if I buy a laptop with i7-7700hq will it limit my GPU? Especially games like bf1 which uses much cpu power.

i7-7700k laptops are out of my budget unfortunately 🙁. Just because of this is I might change laptop model to i7 7700hq and gtx 1060.

That CPU is just a hair slower than a desktop i7-3770 which does not bottleneck a gtx 1070.

But as I can see here there is bottleneck and it is pretty obvious:

(it's for i7 6700hq but 7700hq is quite similar like %3 difference in some cases)

Any other ideas?

I'm not sure why you're calling those bottlenecks. They aren't.

(first link) GTA V 50-70fps at max settings w/ 4x MSAA + max advanced settings @ 1080p is very good performance, that's just barely below what I get on my 4790k and 980ti at identical settings
(second link) Battlefield 1 was running at or around 100fps more often than not at ultra settings
(third link) Black Ops 3 was running well above 100fps most of the time

There's no evident bottleneck with a 1070/6700hq or 1070/7700hq combo. The only bottleneck regarding that laptop is fitting it into a normal sized backpack.

In normal conditions as I know GPU must work %98 or above stable ( unless v-sync or something like that limits usage). Correct me if I am wrong.

In these cases it looks like gtx 1070 not working on full capacity so there must be something prevents it. That's why I call this cpu bottleneck.

GPU usage will vary with each game, depending on resolution and graphical settings. Running a GPU @ 98% only gives you an indication that 98% is being used to process the game you currently playing at whatever resolution your playing.

This is what you need to know:

Example:
GTAV: 1080p resolution - max settings - nets you 60 fps with 75% GPU and 98% CPU.
GTAV: 1440p resolution - max settings - nets you 60 fps with 98% GPU and 75% CPU.
There is no bottleneck in either scenario. The load on either the CPU or the GPU is dependent of resolution and will change

Example:
GTAV: 2160p resolution - max settings - nets you 60 fps with 100% GPU and 50% CPU.
In this example only the GPU would be the bottleneck.

Exactly.

It's also worth noting that the BF1 clip you (game07) originally provided was streamed with OBS. With or without x264 encoding, OBS is a CPU hog. It's unclear as to what capture softwares were used for Black Ops 3 and GTA V, but still, "bottlenecking" isn't the right term.

Another important thing to remember is that laptop hardware always has problems. It just does. That's the nature of packing powerful circuitry into small spaces. It's highly likely - if not absolutely certain - that the laptop's microcode/BIOS has built in thermal/power/load limits. That's why even my laptop's 960m doesn't hit 100% load in many games despite it being paired with a 6700HQ.

I wouldn't worry so much about bottlenecking. Laptops will never perform as well as desktops, regardless of whether they use laptop or desktop components. Just ask yourself if you're willing to pay extra for the higher performance of the 1070, as major or marginal as it may be in any given scenario.
