Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

As the best gaming laptops get thinner and lighter, the companies that make them are pushing new features to stand out and provide a competitive advantage. On the Alienware m15 R3 ($1,371.99 to start. $2,165.79 as tested), that includes options for a 300 Hz 1080p display or 4K OLED.

This year’s model also comes with Intel’s 10th Gen H-series processors, and, in our review unit, a full-sized Nvidia GeForce RTX 2070. That all makes the Alienware m15 R3 a portable, powerful eSports or AAA gaming machine. But the thin chassis does have some disadvantages, as it got hotter than we would like.

    No it's not. Not until humans develop cybernetic eyes.

    Actually yes it is, the higher the refresh rate the sooner information gets to your eyes and your brain can act on it, like with anything there are diminishing returns, but there is a measurable difference.

    Diminishing returns are true - within human physical capability. 300Hz is well beyond that.

    Can you really notice the difference between 144hz and 240?

    I have a m15 R3, ordered it on release day. The RAID 0 drives are m.2 SATA, while the single "storage" drive is NVMe (x2 PCIe 3.0). First thing I did is change the boot drive to the single NVMe drive. What stupid company sets a RAID 0 array as a boot drive?

    Eh, I don't really think so (the part about 300Hz being "well beyond that" -- I definitely agree with the diminishing returns aspect). Like, watching a video at 144Hz vs. 240Hz vs. 300Hz (and an accompanying framerate), I don't think anyone would notice. That's because cameras and video capture and then replay things in a different fashion.

    But playing a game, with the live feedback loop, there's certainly a difference between 60Hz and 144Hz, and even from 144Hz to 240Hz. I suspect for serious (ie, 'pro' gamers like Ninja), yes, 300Hz and 300 fps vs. 240Hz and 240 fps would actually yield a modest 3-5% improvement. It's fuzzy math for sure, and no pro gamer is actually going to use a 15-inch laptop for a competition. There's a reason pros have standardized on 24-inch (sometimes 21.5-inch) displays.

    Older Alienware keyboard was better. Heat was lower as well. I dont like their new Design at all.

    The same can be said about the Desktops.

    Ah...the olde Hz discussion. Perhaps a nod to that other critical factor, FPS, would be in order? - a high Hz will be increasingly pointless if there's a significant FPS imbalance there! What's also hugely significant is that the drive for high Hz does, by definition, lock the gamer to a 'low' resolution experience in the vast majority of cases - unless you're happy to knock down eye candy also. Add to that the requirement to purchase a top end gfx card and CPU.
    For the vast majority of us, operating outside the 'pro-gamer' scene, spending that money would be accompanied with higher resolution gaming as the primary goal. Of course, ultimately, every one of us (pro-gamer included) would like a combined experience of max res gaming, max FPS and max Hz, withing 'diminishing returns' reason. Tag a future VR experience to that for that final touch.

    Try this... See whats your reaction time. Your clicking reaction time is easily over 100ms. Way higher than even 60Hz refresh rate of ~17ms.

    We also need to include lag.....haha.... internet connection speed. 20-30ms is considered very good.

    Higher refresh rate is not about getting information to your eyes sooner, its about motion looking smooth and not jerky. Of course, your GPU has to be able to keep up. If your game is running at only 50fps, then having a 300Hz display isn't going to do anything.

    I've seen/used both 144hz and this m15 R3 w/300hz. Yes, you can see a difference. On the 300hz display, just moving windows around the screen is amazingly smooth, unlike anything you've seen. The difference is very noticeable.
