Design, Build Quality & Upgradeability

The current HP Omen gaming laptop hasn’t undergone any major design changes. It looks like the previous model except for two things.

HP finally wised up and got rid of the red streaks and red logo. And the hinge is no more two straight “pillars” connecting the display to the laptop.

But, a more traditional hinge except that is doesn’t cover the whole length of the laptop. To be honest, the design looks better. It is simple and minimalistic. However, there is only one colour – black.

When it comes to build quality. The HP Omen is made from a mixture of brushed aluminium, matte finish and plastic. The lid and keyboard deck is brushed aluminium whiles the rest of the body is plastic.

A strong laptop with almost no flex. Unfortunately, it is not the thinnest and slimmest laptop. The HP Omen is quite thick and heavy.

It weighs 5.4 pounds (2.4 kg) and it is an inch thick. It is certainly not the most portable gaming laptop. But, you can still carry it around.

All the ports are found on the side including the Thunderbolt 3 port. And the keyboard is RGB four-zone backlit.

Opening and upgrading the laptop is easy. Pop-up off a few screens and remove the plastic underside.

You then have access to the RAM, SSD, WLAN card and HDD. All which are upgradeable. The rest, as with all laptops can’t be upgraded.

For the Alienware. It is a beautiful gaming laptop. More beautiful than a lot of gaming laptops including the HP Omen.

The honeycomb grills, LED RGB strips running around the edges of the rear vents, RGB logo and power button tell you that Dell took a different approach this time.

The rear exhaust vent protrudes out of the back of the laptop giving it that alien spaceship look. If you haven’t noticed it looks just like the Alienware Area 51M.

And it is. Just that it is slim and lightweight i.e. 4.75 lbs (2.16 kg) and less than an inch thick. That means you can easily carry this anywhere.

The Alienware also comes in two colours – dark side of the moon (greyish black) and lunar light (white). A beautiful laptop overall.

The build quality though is so and so. It is alright but at its price point, it should have been so much better.

It has few body creaks, flexes a bit and quite sturdy. However, compared to the HP Omen it is weaker.

The display lid and keyboard deck are made from magnesium alloy with a smooth finish whilst the rest of the laptop is plastic.

Most of the I/O ports are found on the rear whiles the rest are on the side.

On the keyboard deck, the keys are well-spaced and are RGB individually lit. You will also notice that the power button is the Alienware logo.

Now here is where the Alienware disappoints – upgradeability. Opening the laptop is easy.

But, once in you quickly notice that the motherboard is flipped and the only upgradeable component there are SSDs. You can’t change the RAM and the WLAN. And there is no space for an HDD.

NB: The newer Alienware models have removable RAM, WLAN and SSD storage. The motherboard also isn’t flipped.

The Alienware has a better display. It is brighter, sharper and has a high colour accuracy. The HP Omen, on the other hand, has an average display. It is a sharp display but the colour accuracy is average.

Whereas with the Alienware you can easily use it outdoors. Both have 15.6 inch and 17.3 inch Full HD displays depending on which one you choose.

For the refresh rate, the 15 and 17 inch HP models have 144Hz refresh rate.

The 15 and 17 inch Alienware models have 60Hz, 144Hz, 240Hz and 300Hz refresh rates. The higher the refresh rate the better.

Because high refresh rate displays reduce screen tearing, stuttering and ghosting during gameplay. Too much of it can negatively impact the gaming experience.

The two laptops have high refresh rate displays. Both also have 4K 60Hz display options. Except that it is a 4K OLED display for the Alienware.

Overall, the Alienware has better viewing angles, brightness, sharpness and colour accuracy making it a better display.

Alienware wins this round.


Hot temperatures can be an issue because your laptop power throttles to reduce temperatures. And this impacts performance because there is going to performance drops.

And this is readily seen during gaming when FPS in games drops sharply.

High temperatures also slowly damage your laptop over time and can cause crashes. Now both laptops run hot. But, the question is between the two which is cooler?

The HP Omen is the cooler one. It is thicker and has larger fans. That means more airflow resulting in lower temperatures.

The fans are also able to rotate at high speeds which brings more airflow and push hot air out resulting in better cooling.

The HP Omen doesn’t have a lot of heat pipes. In total, there are about five heat pipes. One heat pipe is shared between the CPU and GPU.

However, the heat plates the pipes are on are huge and cover the majority of the space them.

Now for the Alienware M15. Dell calls the cooling system Cryo-Tech V3.0. A fancy name for a cooling system that doesn’t do its job well.

The Alienware is a hot laptop and it can reach high temperatures quickly.

The culprits are its slim form-factor and flipped motherboard. It’s known that slim laptops get hot quickly.

For the flipped motherboard, usually, gaming laptops have a lot of vents on the underside. And normally covers almost half of the underside.

But, the Alienware doesn’t have a lot of underside vents. The laptop has vents on the side and underside.

Now for the heat pipes. The Alienware has a total of four heat pipes.

Two are shared between the CPU and GPU. At the same time, each one has their own.

Also, instead of the fans being next to the rear vents, it’s rather the heat pipes. Combine that with a flipped motherboard and slim form factor.

It becomes easy to see why the Alienware runs so hot. The heat plates, however, do a great job of occupying a large surface area.

There are two major ways of reducing high temperatures in the HP Omen and Alienware. The first is applying thermal paste.

Thermal paste improves heat conductivity in the cooling system resulting in cooler temperatures. For the HP Omen applying the thermal paste is going to be easy.

But, for the Alienware, unless you know what you doing it is not advisable to do so. Because the flipped motherboard is going to make it difficult.

You have to completely disassemble it before you can apply the thermal paste. And if you don’t know what you are doing. You might easily destroy something.

This brings us to the second method. Undervolting is reducing the amount of voltage being used by the CPU and GPU.

High voltage means more power and more power means more heat. Reduce the voltage and you reduce the temperatures.

Combining the two methods will lead to better and cooler temperatures.

Considering the two gaming laptops right out of the box without making the necessary changes (thermal pasting and undervolting).

The HP Omen wins. It has a better cooling system and because of its thickness. It runs cooler than the Alienware.


The most important part of the comparison – performance. Both are powerful gaming laptops. But, the HP Omen is the more powerful one when compared to the same Alienware configuration.

Why? Because it has a better cooling system and gives it a slight edge over the Alienware. Nevertheless, you will still get insane performance on both. You will be able to hit high FPS on AAA title games on the highest preset.

Each has a Intel Core i5, i7, i9, AMD Ryzen 5 and 7. For the best value performance, the AMD Ryzen 7 and Intel Core i7 will be the best option.

The HP Omen can also take up to 64GB RAM. Whereas, the Dell Alienware can take 32GB.

There is also an AMD Ryzen version of the HP Omen which is a great value laptop.

However, it can’t be upgraded so you have to be careful choosing the amount of RAM you want. If you get the 8GB RAM you will be stuck with it.

When it comes to the graphics card. The HP Omen has GTX 1650 to RTX 3070 options.

The Alienware options start at GTX 1660 Ti to RTX 3080.

Battery Life

For the battery life, the Alienware wins this. It has a bigger battery – 76 WHr – and so a longer battery life. You are looking 5-6 hours under consistent use before it runs.

The HP Omen has 69 WHr battery and it can last 4-5 hours under consistent use. Since both are powerful gaming laptops. Don’t expect long battery life.

HP Omen 15 Vs Alienware M15: Which One Should You Get?

OK. So we have compared the most important parts of the HP Omen and Alienware. However, it is still a hard choice.

The HP Omen has better cooling, build quality, and performance. On the other hand, the Alienware is slim, lightweight, and beautiful and has a better display.

If you want better performance, easy upgradeability and build quality. Then the HP Omen is the one you should get.

But, if you don’t mind the flipped motherboard, soldered RAM and WLAN card. But, prefer a beautiful design, slim, lightweight and superb display. Then the Alienware would be a solid choice.

Overall, both are great gaming laptops and do a fantastic job of running games.
