    I know the info im looking for is probably in the 400 page owners thread but without a way to search the thread im just gonna ask.

    Thinking about trading in my HP OMEN 17T (9880H + 2080 180W) for this m15 (R1?) at costco (9750h + 2060).
    https://www.costco.com/alienware-m1...rtx-2060---144hz-1080p.product.100519380.html

    The OMEN is an absolute beast but I travel for work and carrying around a massive 10 lb laptop and charger just isnt working for me. I can get by just fine with a 2060 on the road and plug into a graphics amplifier at home for some extra juice. My only concern is the CPU keeping up with whatever i throw in the amplifier.

    With the omen, in "performance mode" I can set the turbo boost long in throttlestop to 60w and it will hold 4.1Ghz on all 8 cores when gaming (synthetic loads will throttle of course).

    Are you guys able to hold max all core clock while gaming on the 9750h? Does dell let you turbo over 45w long term? Hoping the answer is yes, the m15 + graphics amplifier seems like a pretty sweet best of both worlds set up. Thanks for the help.

    You will need to repaste (non-LM, recommend Phobya), UV, and keep the laptop on a cooler to hold around 60W. In CB20 this will throttle down to about 3.7GHz. With 2070, no games I've seen come remotely close to CB20 in terms of CPU load and of course you can keep full clocks then (this will likely be game dependent and I'm not a gamer) .
    You can probably push the wattage even higher and get to 3.9Ghz+ on all cores in CB20 with LM.

    Expected CB20 score 3100-3300.

    HTH
    BTW the CPU is H not HK, it's locked (but you wouldn't be able to fully utilise the HK without LM).

    Also, make sure the return policy is solid in case you run into issues. If you get a good unit and are happy to mod it, you will be satisfied, but users occasionally report problems like bad heatsinks. Mine is not perfect either (core diffs, but only in CB20). My unit arrived with bluescreening GPU and needed to have mobo replaced onsite (basically next day though).

    To conclude, your requirements sounds similar to mine except I don't game. The form factor is fantastic on the go. The screen and KB are great. Chassis build quality is solid. Battery life is less then stellar, but enough for my purposes. I haven't had a need for the AGA yet, and I'm happy with this machine. There are just 2 snags:
    * sometimes it power locks to 45W and needs to be rebooted if more sustained power is needed - hibernating instead of sleeping used to resolve this, it no longer does
    * some coil whine is audible when plugged in and the fans are off in a silent room

    Wow, what a response. Thank you!

    Not sure why I put k's after everything, thanks for the correction.

    Sounds like it will work well for me, and Costco's return policy is amazing so no problem there.

    One final question, does the graphics amplifier work with a VR headset? Being able to bring my laptop into the living room and hook up VR for the family to play is pretty cool. Bringing the amplifier too doesn't sound fun, but I don't do it that often so I could live with it.

    Np. Great price BTW. The amplifier is just a chassis for a graphics card, so your question really is "will VR work with that gfx card" (choosing a card which fits the AGA is another matter, as I'm sure you are aware). Performance degradation due to AGA is quite small when using an external display/VR set.

    The 2060 itself will also carry a lot of VR titles (my 2070MQ runs pretty much everything at max settings), and you have a separate HDMI out port at the back of the laptop itself (in addition to mini-DP), which is handy for connecting the headset.

    I was just thinking in terms of some weird technical limitation with the connection, but I guess it's just pci express link so why would there be.

    Good point about the 2060. I'm sure beat saber will run fine, lol.

    Limitations might arise due to driver issues etc, however, I haven't heard of any - the AGA user's lounge would be best place to double check. It's probably also worth picking a card with appropriate output connectivity, especially if you're planning to use an external monitor + VR - switching cables back and forth is no fun at all.
