8750h or i990k ?

Hi.....I notice a lot of the laptops offered for gaming are run with the 8750h cpu and only 2 offer the i9900k

I'm about to purchase a new gaming laptop and will go with 32gb 2666mhz ram and the rtx 2080 cpu

All i'm stuck on is choice of cpu, is the 8750h really good enough for gaming ? i know the i9900k is obviously better but will the 8750h sufficient ?

thanks

Yes, easily.

It's not just about the CPU and GPU though. With a desktop you can, sort of to some degree, talk about those components in isolation from the rest of the system. With laptops, you cant. The same CPU will run at different speeds in different chassis due to how thermal and maybe power management settings have been done by the chassis maker.

I'd strongly suggest waiting for reviews of the new mobile GPUs and systems to be out before making any choices.

Also depends what screen you're using in the laptop. An RTX 2080 on a 1080p screen is a bit of a waste of cash.

Also 32gb RAM is a complete waste for gaming.

I'll also use the laptop for photoshop and plugins plus basic premiere pro video editing so if i choose the 16gb 3000 corsair ram will I be able to add more ram in future ?

the 9900k is an option on the octaneVI laptop according to the options

Yes, the octane isn’t a laptop, it’s a desktop replacement, so it uses desktop cpu’s, has awful battery life and isn’t very portable, but it incredibly powerful.

unless you're targeting 1080p 144+ FPS the 8750H is a great CPU and allows for a truly portable device vs the 9900K

You still get high refresh with the 8750H just not as much, that being said the 9900k has to be severely underclocked in laptops as it overheats...

Not underclocked, but undervolted, very different thing, clocks aren't affected.

And from the first review of the new 17 octane with a 2080 and the 9900k all at stock, temps averaged at 85c, which is a really impressive achievement.

We'll have to wait for more reviews to see if that's a one off.

There’s a good article on undervolting here:

Where is this review? I'd love to read it

What I meant is you won't be running the 9900k at similar clocks as on a desktop system.

Undervolting helps maintain the clocks higher and helps with the CPU overheating which is already a problem in a desktop system with the 9900k

I'd go for a 8700 or i5-8400 non K personally if I was to go for an Octane type of laptop/desktop replacement config

Clocks are the same as on a desktop, it runs at stock speeds so 3.6 base boosting to 5Ghz on 2 cores or 4.7 on all cores.

Cooling was an issue on the previous gen chassis for all manufacturers, not just clevo, but if this review is accurate, then it looks like they've made serious improvements with the cooling. The reviewer experienced no throttling on normal stock clocks.

EDIT: I just rewatched it and saw the boost didn't achieve 4.7 on all clocks, was down to 4.5, so it is limited slighly by thermals, but that was until they undervolted and then it would achieve just under 4.7 on all cores remaining in good temps, which is similar to what we saw with the 8th gen chips in the previous octane chassis.

Personally, I'd agree, I wouldn't go for the 9900k in any laptop chassis, personally I think the only way to effectively cool it is to use a closed loop watercooler as a minimum and a high end one at that. But this does look to be quite a serious improvement on the previous chassis given how much heat the 9900k puts out.

It will be interesting to see the other chips under the same conditions.

The 9900k in a laptop is pointless IMO. The 8700k was pushing heat dissipation to the absolute limit while maintaining near desktop performance. The 9900k won't be close to the desktop due to the TDP power limitations, the chip effectively idles at that haha.

There's only so much you can squeeze out of 95w and I don't think efficiency has improved enough for there to be a substantial enough performance gain.
