I also appreciated the laptop’s kích thước and weight: 15.3 x 12.0 x 1.0 inches, & 5.3 pounds. As 15-inch gaming laptops go, that’s a pretty modest profile, and the laptop should fit easily in most bags and backpacks. The power brick is pretty large and heavy in its own right, of course, but that’s hardly quality to the m15 R4.

Aesthetics aside, the ports merit some praise và some criticism. The selection itself is above reproach. On the right, you’ll find two USB-A ports & a micro
SD slot. On the left, there’s an Ethernet port, a USB-A port & a 3.5 milimet audio jack. These are all well & good.

The back is where things get a little less optimized. In addition to a rather inconvenient nguồn port (slightly left-of-center on the back – just far enough from anything to comfortably reach), there’s an Alienware Graphics Amplifier connection, a USB-C port with Thunderbolt 3 support, a mini-Display
Port & a full-size HDMI port.

On the one hand, the USB-C port is an integral part of Alienware’s e
GPU setup, so there needs to lớn be one on the back of the m15 R4. On the other hand, USB-C is already a common way to lớn charge phones và connect peripherals. Giving users only a single port, then hiding it away on the back of the machine, makes the máy tính feel much less future-proof than it should.

Alienware m15 R4 review: Keyboard and touchpad

While some gaming laptops incorporate full mechanical keyboards (with mixed results), the Alienware m15 R4 keeps things simple with an elegant membrane setup. Each key feels pretty decent, with short travel, fast actuation and a rapid spring-back. While I was very happy khổng lồ go back to lớn a full-size mechanical mã sản phẩm after I was done testing the m15 R4, the keyboard felt perfectly comfortable while I was working with it.

Admittedly, the keys can be a little cramped, và substitution errors were more common than I would have liked. Furthermore, there’s a ton of bezel space around the keyboard, which makes me wonder whether the keys could have been spaced out a little better – or even if it might have been possible lớn include a few programmable keys. On the other hand, I was reasonably pleased with the four-zone RGB options, which sent a gentle rainbow wave across the keys as I typed. (You can change colors or deactivate the RGB entirely in the Alienware software.)

The m15 R4’s touchpad, on the other hand, earns the highest praise I have ever bestowed upon a gaming laptop’s touchpad: “pretty decent.” Unlike the vast majority of laptop touchpads, this one never got in the way, even when I rested my hands on either side of it while typing. It’s positioned in such a way lớn avoid errant palm inputs, và tracks purposeful movements accurately. I still recommend a mouse – especially for gaming – but I wish more gaming laptop touchpads were like the m15 R4’s.

Alienware m15 R4 review: Display and audio

The Alienware m15 R4 that we reviewed came with a 4K, 60 Hz screen; you could also get it with a 1080p, 300 Hz screen, if you prefer higher frame rates. While I can’t bình luận on the 1080p screen, I can say that the 4K screen is extremely bright, and offers a rich màu sắc palette – not surprising, perhaps, since it’s an OLED display.

The screen offers an average of 460 nits of brightness, which can feel downright overwhelming, especially at night. Compare và contrast khổng lồ the hãng asus ROG Zephyrus G14 at 323 nits, or the Acer Predator Helios 300 at only 276 nits. After I set up the m15 R4, the very first thing I did was turn down the brightness, and now I understand why.

(Image credit: Tom"s Guide)

In terms of color, the m15 R4 can display a whopping 211% of the s
RGB spectrum, with a delta-E màu sắc accuracy of 0.32. (Closer to lớn zero is better; this is a very good score.) The G14 scored 117% on s
RGB gamut and the Helios 300, only 106%. Whatever you display on the m15 R4’s screen, it’s probably going lớn look gorgeous.

From a qualitative perspective, I have only a handful of issues, và none of them is a dealbreaker. First, the screen is highly reflective, especially if you sit with your back khổng lồ a window, as I often do. There’s really no way around this issue, except to lớn wear dark clothing, or khổng lồ change where you sit. Second, the webcam is a 720p model that produces fuzzy, washed-out pictures. This feels underpowered for a máy vi tính that uses such powerful hardware otherwise.

Finally, if you want the 4K screen, you have khổng lồ get a secondary Tobii eye-tracking webcam as well, which I couldn’t find a use for. Getting into the pros & cons of eye-tracking for gaming và streaming is beyond the scope of this review, but I don’t think it’s too controversial khổng lồ say that the number of people who want eye-tracking is probably a lot smaller than the number of people who want a 4K screen.

The m15 R4’s built-in speakers get the job done, although I didn’t have much occasion to use them. That’s because even during productivity tasks, the fan blasts loud streams of air almost constantly at mặc định settings. In order lớn hear music, movie, TV show và game audio, I had to lớn turn the volume way up, & the speakers can distort sound fairly easily. “Just get a gaming headset” is a cliché when it comes to gaming laptops, but you really should just get a gaming headset.

Alienware m15 R4 review: Performance

The Alienware m15 R4 delivers where it counts most: gaming performance. This machine is a powerhouse at 1080p, và even holds its own at 4K with graphical settings cranked all the way up. (To save you some suspense: It can’t vày 4K/60 fps, unless you turn down a lot of the secondary graphical settings. But I can’t think of many laptops that can.)

Tom’s Guide put the m15 R4 through its paces with Assassin’s Creed Valhalla (70 fps at 1080p; 35 fps at 4K), Grand Theft tự động hóa V (108 fps at 1080p; 35 fps at 4K), Red Dead Redemption 2 (68 fps at 1080p; 27 fps at 4K) và Shadow of the Tomb Raider (77 fps at 1080p; 33 fps at 4K). Of those games, only Red Dead Redemption 2 fell below our threshold for a comfortably playable 4K experience – và you could always compromise with a QHD resolution.

(Image credit: Tom"s Guide)

Compare và contrast this to lớn the Zephyrus G14, equipped with an Nvidia Ge
Force RTX 2060: GTAV scored 115 fps at 1080p & Shadow of the Tomb Raider scored 49 fps at 1080p. The similarly 2060-equipped Helios 300 scored 55 fps at 1080p for Assassin’s Creed Odyssey (the Odyssey/Valhalla benchmarks are comparable), và 81 fps at 1080p for GTAV. Neither the G14 nor the Helios 300 had 4K displays, so the m15 R4’s versatility already gives it a leg up over the competition.

Qualitatively speaking, I got similar results with Age of Empires III: Definitive Edition, Doom Eternal, Control & Final Fantasy XIV. Since the 4K screen maxes out at a 60 Hz anyway, I generally turned up the resolution & didn’t sweat the frame rate. All of the games ran smoothly, even at Ultra settings – with the exception of Control, with ray-tracing turned on. This caused the frame rate lớn drop into the 20s, và forced me to choose between QHD resolution & gorgeous lighting effects. If games with ray tracing running at full 4K is a requirement, you’ll probably want khổng lồ go with one of the m15 R4’s more expensive configurations.

Given the m15 R4’s powerful hardware, I wasn’t surprised that it ran games beautifully, whether I was exploring populous cities in Eorzea, or building up Dutch armies in the New World. What did impress me, though, was just how rich the colors looked, particularly in Doom Eternal’s rocky red landscapes. The OLED screen supports a gorgeous, vibrant palette (remember: 211% of the s
RGB spectrum), & no other medium shows this off as beautifully as gaming does.

In terms of artificial benchmarks, the m15 R4 earned a Geekbench 5.3 score of 7,636 — quite high, in a vacuum, although we haven’t run the chạy thử on any other gaming laptops just yet. Instead, compare và contrast the m15 R4’s score on Geekbench 4.3: 30,043. This is just shy of the G14 Zephyrus’ 30,181 points, although it’s admittedly odd that a newer, more powerful machine would earn a lower score.

It’s also worth mentioning the Alienware suite of software, which lets you set up fan, lighting và performance profiles for various games và apps. The software can also keep your system up to date, and connect you with customer support representatives. As built-in software goes, it’s inoffensive, & it actually works better here than it does on Alienware’s R11 desktop. Once I installed all the requisite hardware updates, however, I didn’t see much need lớn use it again.

Alienware m15 R4 review: Heat

One of my biggest complaints about the Alienware m15 R4 has to bởi with how the máy tính xách tay manages heat. In terms of raw temperatures, it’s not so bad: I rarely saw the GPU exceed 60 degrees Celsius. While running productivity software, the touchpad hovers around 81 degrees Fahrenheit, & the keyboard seldom exceeds 96 degrees Fahrenheit, which is just a hair north of our 95-degree comfort threshold.

While gaming, however, the keyboard can reach temperatures exceeding 108 degrees Fahrenheit, which can be troublesome if you rest your fingers on the keyboard in-between actions. (The touchpad does not get very hot, but I also don’t know many people who trò chơi with a touchpad.)

(Image credit: Tom"s Guide)

The bigger issue is that the fan, which does an admirable job of cooling the system off, makes a huge, constant racket. My domestic partner was sitting next to me at our dining room table while I tested the machine, & asked why her papers kept getting blown around. The fan hâm mộ was too loud lớn hear music or Netflix audio tracks, to say nothing of games. It wasn’t until I discovered the “Quiet” fan profile in the Alienware software that I was able to restore a modicum of peace in my apartment.

I realize that a loud fan is very much the lesser of two evils when it comes to lớn gaming laptops. After all, a GPU overheating is a much worse outcome than a lot of unwanted noise. But even by gaming máy vi tính standards, the m15 R4 is an incredibly loud device, và its default settings are not good at finding a balance between noise và temperature.

Alienware m15 R4 review: Battery life

If the Alienware m15 R4 has one significant weakness, it’s in the product’s battery life. While our general máy tính battery test – surfing the website constantly in Microsoft Edge – rated the m15 R4 at four hours and one minute, I was never able khổng lồ get anything close lớn this, even just working with Microsoft Word and Google Chrome. With medium brightness & a stable mạng internet connection, the máy tính xách tay had, at best, about two hours of life in it.

While gaming, the situation is even bleaker at one hour và 14 minutes, according khổng lồ our lab tests. In practice, I got about 45 minutes. It’s better than nothing, but the m15 R4 is not a very good companion for taking long trips – unless you’re seated next lớn a nguồn outlet.

Alienware m15 R4 review: Verdict

The Alienware m15 R4 is easily one of the best gaming laptops I’ve ever reviewed. And, to lớn be fair, for $2,150 (at least!), it really should be. You vị indeed get what you pay for, between a powerful GPU, a fast SSD, a gorgeous design và a vibrant screen.

While I wish the fan hâm mộ were a little quieter, & the battery lasted a little longer, these are ultimately acceptable sacrifices in a machine that’s designed primarily with home gaming in mind. If you decide khổng lồ invest in an Alienware Graphics Amplifier và use the m15 R4 as an ersatz desktop, so much the better.

In terms of competitors, the Zephyrus G14 is still worth considering, although since that computer has a last-gen GPU, it’s a tougher sell now than it was a year ago. Stay tuned while we reviews some more laptops with 30-series GPUs – or pick up the m15 R4, which should serve you well for the next few years.

As promised in the reviews, I wanted to lớn give you a side-by-side comparison of the Lenovo Legion 5 Pro and the Dell Alienware m15 that I’ve been dealing with lately.

BTW, you’ll find the detailed đánh giá via these links above.

I figured these laptops might be on some of your shortlists, especially if you’re considering a modern máy vi tính built on an AMD Ryzen 5000 processor & a higher-power variant of the Nvidia Ge
Force RTX 3070 máy vi tính graphics chip.

I think if you read both my reviews, you can clearly see that I liked the Legion 5 Pro more. But there are some features of the Alienware mã sản phẩm that I liked, and are worth mentioning và comparing against the Legion 5 Pro.

Here’s an in-depth look at my comparison. But first, a quick specs sheet of the units that I had.

Here are our thoughts on the latest iterations of these lineups, the 2023 Lenovo Legion Pro 5 & 2023 Dell Alienware m16 lineups.

Design and build

When looking at the specs, you might think the Lenovo is a much bigger model. But in reality, they are practically the exact same size. The height and width are almost the same, with the Lenovo being a tiny bit taller on the vent side. The Alienware’s vents make it a hair deeper though. Considering the weights are so close together, you might as well just điện thoại tư vấn it a tie.


It’s not a perfect win though, as there was one thing about the Alienware screen that was nice, và that was the color space. The Alienware panel has a gamut of 100% DCI-P3, while the Lenovo panel is only 100% s

Other notable differences:

Lenovo has a much brighter panel at 500 nits vs 375 nits.Lenovo has a significantly higher contrast ratio (1259:1 vs 902:1)Alienware has a higher refresh rate (240Hz vs 165Hz)

I’ll miss the 100% DCI-P3 colors, but Lenovo has the better panel, in my opinion.

Differences in Hardware & performance

There aren’t too many differences in the hardware, which is why you might be choosing between these two models in the first place. Both models have the same CPU, GPU and RAM. Both models also have replaceable RAM modules & 2x SSD slots.

One interesting difference in the SSDs, though, is what Dell decided to vì (or not do). Instead of being normal lượt thích Lenovo, which offers 2x 1TB drives populated, the Alienware only has 1 SSD slot occupied. And with a half-size SSD drive.

Not only would it be difficult to replace the SSD due lớn the length difference, you can’t even put a second SSD in at all without purchasing a special mount from Dell.

The only other major hardware difference is in the Wifi module, where Lenovo chose Intel and Dell chose Killer. I found no difference in either in any of my use, although I hear that the Lenovo struggles with bluetooth connections for controllers a bit more. I haven’t confirmed this though, so take it was a grain of salt.

There are some differences in performance, but I need to be fair & disclose that my benchmarks were taken before Alienware fixed their CUDA vi xử lý core fiasco. Dell “accidentally” disabled 10% of the CUDA cores on their 3070, but this has reportedly been resolved in a recent v
Bios update, & that should translate in a bump in scores. Nonetheless, see below for my comparison at the time I’ve reviewed these laptops.

In the meantime, I’ve also reviewed the Legion 5 17-inch RTX model over here, as well as the mid-tier RTX 3060 version of the Legion 5 15-inch over here.

There’s quite a bit you can gather from this comparison. For starters, the CPU performance is clearly better on the Lenovo. It’s almost definitely because the cooling solution on the Lenovo unit actually works, while on the Alienware almost all of my testing resulted in temps around 100C.

It’s hard to make concrete comparisons on the GPU numbers & gaming benchmarks, because of the potential improvement from the CUDA vi xử lý core fix on the Alienware m15. At best though, the GPU benchmarks would increase by 10% và the gaming benchmarks somewhere between 5-10%(since some may be CPU dependant).

So even with the 10% correction, the GPU benchmarks on the Alienware are slightly lower, và it’s mainly because of the 125W TGP limit, while on the Lenovo it’s up to lớn 140W.

At the same time, the gaming benchmarks are going lớn be slightly better on the Alienware though, because the Lenovo is driving 11% more pixels than on the Alienware panel. Regardless, both models have really good performance, so unless you’re picking nits about a few fps, you can’t go wrong with either model.

Battery Life

There wasn’t a whole lot of difference in battery life between both laptops. The Alienware m15 has an 86Whr battery, while the Lenovo has an 80Whr. But in my testing, I got equivalent results.

What’s a bigger giảm giá khuyến mãi is the fact that the Alienware has Advanced Optimus, while the Lenovo just has Optimus. You’d think this would be a positive for the Alienware, but it actually isn’t – at least not yet.

In my testing, I actually found Advanced Optimus khổng lồ be really buggy. You can read my full review for more details, but to lớn summarize, I just turned it off & controlled the graphics manually.

The Legion 5 Pro, on the other hand, uses the d
GPU by default, & has a MUX switch lớn enable Optimus as needed. It’s the same amount of effort to lớn switch on và off as the Alienware, just less buggy. You could go either way here though.

Other Stuff

Other notable things to discuss are both laptops having the computer nguồn on automatically when opening the lid. This of course can be turned off in the bios, but Alienware goes a step further và has a biometric webcam. So with that model, you can literally lift the lid and start working.

Since we’re on the topic of webcams, the Legion 5 Pro has a feature that I really like, which is the ability khổng lồ turn it off. On the left side of the laptop, there’s a physical switch that removes power to the webcam. A very nice privacy feature that I would hope khổng lồ see on all laptops someday.

As far as the sound quality goes from the speakers, I think the Legion 5 Pro has a slight edge, but not by much. Both laptops have down-facing 2x2W speakers, which both lack bass. But the Lenovo’s speakers were a little bit louder from my measurements.

I was able lớn tune the Lenovo’s speakers to lớn sound better, but I probably could have done the same, had I spent more time fiddling with the Alienware settings. I’d just as well gọi them equal.


You can easily kết thúc the argument with the price difference. The point being, the Legion 5 Pro is significantly less expensive than the Alienware m15. At the time of this review, the Alienware m15 r5 costs $2179, và that’s not including the Cherry MX keyboard, which would run you another $100.

The Lenovo Legion 5 Pro is normally priced at $1959, but at the time of this comparison, it’s actually priced at $1849. A real bargain if you ask me.

Final Thoughts

I think after seeing the price difference, it’s hard khổng lồ justify choosing the Alienware m15 over the Lenovo Legion 5 Pro. Not only vày they both have similar hardware specs, but the Lenovo has a bigger screen in the same kích thước chassis. It also has a sturdier build, bigger trackpad, và more IO.

The Alienware on the other hand has a better keyboard, higher gamut screen, và a biometric webcam, which may tempt you. But when you throw in the worse thermals và the lower-powered GPU, I think the appeal starts lớn fade.

I’m sure Alienware fans will still opt to lớn buy the m15, and that’s fine. It’s not a bad laptop. But the value, in my opinion, is much much better in the Legion 5 Pro – I would argue it’s going to lớn be one of the best picks this year has to offer.

I hope this helps you make a more informed decision though. I no longer have the Alienware m15, but I decided lớn keep the Legion 5 Pro, so I’ll have it around khổng lồ answer any more questions you may have. Please leave me a phản hồi in the section below and let me know what you think.
