Now that we have established what the primary similarities and differences are from a technical point of view, let’s dive into a detailed analysis of the two laptops.


In terms of performance, I would say that the Alienware x15 r2 takes the lead. It comes with an equally powerful processor but has more clock speed on the RAM.

While Alienware m15 r7 does provide more upgradability options, which will significantly enhance its overall performance, at base levels the x15 r2 easily takes the lead.

The reason is the integration of low-powered RAM with higher clock speeds which counts where it matters. So, when you are using performance-intensive apps or gaming rigorously, this speed will stand out and allow the former to perform better.

Even on the benchmarks, the x15 r2 has scored better in terms of performance standards. However, when you upgrade the RAM to its maximum, the m15 r7 takes the lead as its RAM can be upgraded to 64 GBs while the x15 r2 is limited to only 32 GBs.


Both laptops almost provide equal specs in terms of CPU, GPU, and performance components. While you certainly have more options with the latter of the two, in terms of gaming, their performance is pretty much the same.

However, if you have maxed out the specs, then you will get to experience better performance in the m15 r7. Also, it really depends on which dedicated GPU you have. While both laptops provide equal options, you must know that having a more powerful GPU would certainly lead to better gaming performance.

Both laptops offer the same display size and the same resolution options. However, when it comes to screen-to-body ratio, the m15 r7 offers slightly more screen than the x15 r2.

Hence, even if minor as a thread, the m15 r7 takes the lead in terms of display size. You have more screen space, which means you will get to experience a more immersive viewing experience.

Most people won’t be able to tell the difference between the two, but for a passionate gamer, even a fraction of an inch counts. The thinner side bezels in m15 r7 provide you with slightly larger screen space.

Battery Life

The m15 r7 provides you with 2 options. You can choose the 56 Wh or 86 Wh battery depending on the specs you are choosing. On the other hand, the x15 r2 has only an 87 Wh option.

While the rest of the specs about the battery are similar as both are Lithium-ion and support fast charging, this minor altercation can make all the difference.

The x15 r2, having a more powerful battery, provides a little more battery life and allows you to enjoy gaming or whatever you are doing on the laptop for a little longer. While the difference is little, it does provide the x15 r2 an edge over the m15 r7.

Connectivity Options

There are some significant differences between both laptops in terms of connectivity options. In terms of wireless connectivity, both laptops offer similar chipsets for Wi-Fi and Bluetooth. However, when it comes to ports and other connectivity options, there are noticeable differences.

The x15 r2 comes with additional USB Type-C slots, 2 in total, and also an SD card reader, which is absent in the m15 r7. On the other hand, the latter has an additional USB Type-A slot and an Ethernet port, which is not present in the former.

So, considering the USB Type-C as a necessity in the modern world, we would rank the x15 r7 a bit higher because it has two USB Type-C ports. However, it does take a little blow because of the lack of an Ethernet port.

Having no Ethernet port is not taken lightly by passionate gamers who do not rely on wireless connectivity and want a LAN connection for better internet speed. So, in that aspect, the m15 r7 takes the lead by providing one RJ45 Ethernet port.


Both laptops are almost have same size but in terms of weight, the x15 r2 is slightly lighter than the m15 r7. While the weight difference is only 0.32 pounds, it does give the x15 r7 an edge.

So, in terms of portability, I would suggest that x15 r7 takes the lead. It is slightly more portable than the other laptop and provides lower weight. On the other hand, while m15 r7 does weigh slightly more, it is justifiable considering its upgradability options.
