The Dell Alienware m15 R7 excels in gaming and general use, offering solid performance at a generally lower price compared to its competitor. It combines a high refresh rate display and hardware ray tracing, which is favorable for gaming, with the portability of a 15.6-inch screen. On the other hand, the Razer Blade 18 has a larger, more vibrant display with a slightly higher resolution, more RAM and storage space, and a more powerful main processor and GPU, making it highly suitable for demanding tasks like 3D rendering, machine learning, and engineering software. However, with this boost in capabilities, the Razer Blade 18 is generally more expensive and heavier, and both laptops offer around the same battery life, which is modest. If performance for intensive tasks is a top priority and cost is less of a concern, the Razer Blade 18 may be more appropriate. If you prefer a balance between cost, performance, and portability for gaming and general use, the Alienware m15 R7 could be a better fit. Give Feedback

Brandon Hill | October 2022
"The Alienware M15 offers solid gaming and leading endurance. It makes the most of its CPU and GPU while delivering stellar battery life for a gaming laptop. Opening the lid presents a full-size keyboard with honeycomb cutouts above it on the deck. An oblong RBG lightning element surrounds the entire rear panel and can be color-synced with the other lights on the laptop. There’s not a lot to dislike about the M15 Its productivity performance lagged in some areas, particularly in the storage benchmark, and it’s a bit heavy. Alienware has a clear winner here with the M15 based on its strong overall performance and endurance."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
