    I believe you mean i7-8700? I'm not seeing the 9700K listing if otherwise.

    This should help - https://cpu.userbenchmark.com/Compare/Intel-Core-i7-8750H-vs-Intel-Core-i7-8700/m470418vs3940

    I own the 17" version of the second one you are considering. Considering it has a G-SYNC enabled display it is the one I would pick all day long for gaming. It will probably run slightly hotter than the 8700H version out of the box.

    The N960TF has a slighly longer estimated battery life. Both models use the same battery.

    No, I mean the i7-9700 (non-k)
    You can select the i7-9700 from the drop down menu here:
    https://clevo-computer.com/laptop-c...9/clevo-n960tf-desktop-laptop-nvidia-rtx-2070

    Does G-Sync really make a difference when playing with 144Hz?

    The CPU is the main reason why I consider to buy the CLEVO N960TF. It has the better CPU. However, I'm afraid that the thermals and the power limitations of the laptop will throttle the CPU to the point where it ends up at the same level as the 8750h. What do you think?

    I see now!

    Better is going to be relative to your usage. The i7-9700 t has no HyperThreading, 2 more cores but 4 less threads than the 8750H, and 20W higher TDP. In a laptop those are potentially somewhat worse qualities!

    Ideally you will see more frames in games and more points in benchmarks with the 9700 because the 8 cores are running at 4.7GHz rather than 6 cores at 3.9GHz (8750H), not to mention the 12MB L3 cache vs 9MB. However, it will be at a higher TDP and possibly more voltage which requires more cooling that may potentially end up thermal throttle and downclock to compensate. Or perhaps it will run 100% fan speed all the time? This all comes down to the heatsink and fans of the N960TF.

    In my opinion G-SYNC is a must have for gaming after you've experienced it. Especially when spending multiple thousands of dollars on a laptop, I do NOT want to see screen tearing of any kind while gaming. Before using a G-SYNC 144Hz screen I had no real preference. Now I'll never go back, as they say.

    As far as games are concerned, the 8750H is more than capable to run anything. You will not be losing out on experience or gameplay by not choosing the 9700. In fact, I'd wager most people couldn't tell the difference in-game and you'll only suffer as a result of thermal throttling unless you take preemptive steps to cool it down like repaste with better thermal paste, undervolt, and adjust the fan profile(s).

    To be fair, they will/would both need some tweaking out of the box to perform their best. The i7-9700 is the more unique choice, but I'm not seeing any justification for it if you are simply wanting a laptop to game on. IF you have some other CPU specific task to perform, maybe that would be the real determining factor.

    @4W4K3 I want to game on it, but I also want to work on it (video editing & rendering & 3D editing & rendering)
    That's why the i7-9700 version sparked my interest.

    I heard before that with a 144hz screen it's almost impossible to notice the difference between G-Sync on & off. Is that not true?

    This is the heatsink of the 9700 laptop:
    You think it will thermal throttle with the i7-9700?

    The 65W will be kept to which will mean turbo is not super aggressive but I think it will take the lead in CPU bound tests.

    It’s hard to say if something will throttle based on a picture. I believe the PB51EF-G will better cool it’s hardware. But since I don’t own one I can’t say for sure.

    Have a look at similar models with similar cooling - http://forum.notebookreview.com/thr...6-n957tp6-n950td-n957td-owners-lounge.812481/

    As I stated previously; G-SYNC for gaming is a great feature. It costs a small premium for a reason. There is a noticeable difference switching it off and on depending on application. In very high FPS games screen tearing is a real thing.
    It may make no difference outside of games, but given your uses include gaming and one of the laptop options includes G-Sync it is worth mentioning.

    Depends on what you're playing I guess. I bought a 144Hz FreeSync panel for an NVidia GPU, and without any kind of synchronization I have yet to observe tearing.

    Exactly, it will depend on the game. I can get 200-300FPS in World War Z on ultra, but without v-Sync or G-Sync enabled there will be some tearing even on a 144Hz screen. A 240Hz screen would be better, but I bet I could make even that year with the right application.

    You can use adaptive sync or sync of some variety and limit to 144Hz/FPS for no tearing. The trick here is benchmarking, you lose all the performance point above 144FPS. Fine for some! I want 2-300FPS without tearing even on 144Gz screen.

    In the grand scheme of things it is entirely personal preference. I see G-Sync as a valuable addition while gaming. I also see it as value added to the worth of the laptop come resale time. I also believe the screens paired with G-Sync are of higher quality with better QC. Just my opinion!

    2 real cores > hyperthreading, especially for gaming. Also GSync or any VRR is ghodly vs dealing with vsync. once you experience the near perfect low lag and fluid gameplay, you can't go back.
