The Dell Alienware m15 R7 offers better performance for 3D rendering, machine learning, and gaming due to its higher-end GPU and faster refresh rate display. However, it is heavier and has a shorter battery life, making it less portable than the Dell Precision 5470. The Precision is lighter, offers better battery life, and has a higher portability score, which might be more suitable for general use and professional work that requires mobility. The Precision also has a higher display brightness level, which is beneficial for work in brightly lit environments. If portability and battery life are more important to you than gaming or 3D performance, the Precision 5470 is the better choice. If you prioritize gaming or intensive engineering tasks and don't mind the additional weight and shorter battery life, the Alienware m15 R7 would be the preferable option. Give Feedback

The Dell Alienware m15 R7 has a better screen than the Dell Precision 5470 for general use, gaming and AI, and engineering and design, while the Dell Precision 5470 has a better screen for content creation, and software development.
For general use, the Alienware's superior resolution and panel type provide sharp and vibrant visuals, while its brightness ensures comfortable visibility under various lighting conditions, making it excellent for everyday tasks; the Precision, with slightly lower brightness and resolution, offers good but not as compelling visuals for similar tasks. In engineering and design, the Alienware shines with a wider color gamut coverage that ensures more accurate color representation vital for detailed work, outperforming the Precision despite both having good color accuracy. However, for gaming and 3D tasks, the Alienware falls short due to a lower refresh rate, which means less fluid motion, while the Precision similarly struggles with gaming and 3D content, emphasizing that neither is optimized for high frame rate demands required in these scenarios.

Although they have very similar scores, PerfectRec considers Dell Alienware m15 R7 to be very good for engineering and design, while the Dell Precision 5470 is good.
The Dell Alienware m15 R7 is equipped with a higher-end AMD Ryzen 9 CPU and Nvidia RTX 3070 Ti GPU, offering robust performance for demanding engineering tasks and design work, while also providing excellent screen quality; however, it may be less portable and could generate more operating noise. On the other hand, the Dell Precision 5470, while still suitable for engineering and design with its Intel i7 CPU and Nvidia RTX A1000 GPU, trades off some performance for better portability and potentially quieter operation, along with a good quality screen and keyboard.

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."

"The Dell Precision 5470 is a mobile workstation that's far more portable than most alternatives. Between its slim 14-inch design and top-quality MIL-STD 810H build, it's one of the best options around for taking professional-grade performance on the road or to the job site. There are tradeoffs for its portability, and users of the most demanding, graphics-intensive applications will need to carry something heavier. But the Dell's exceptional battery life underscores its desirability as the most portable workstation we've seen."
