PCMag
Mark Knapp | January 2023
"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Plus, those alternatives are much more enjoyable after work."

Allen Ngo | May 2022
"After making a huge splash with the original 2021 model, it's expected that the 2022 refresh would be more of a minor update to an already impressive machine. It adds a higher resolution webcam (720p to 1080p), faster CPU (Ryzen 9 5900HX to Ryzen 9 6900HX), faster GPU (RTX 3070/3080 to 3070/3080 Ti), faster RAM (DDR4-3200 to DDR5-4800), faster M.2 SSD support (PCIe3 x4 to PCIe4 x4), newer WLAN module (Killer AX1690i to Qualcomm WCN685x), and a MUX switch for the new integrated Radeon 680M GPU. It's indubitably an upgrade especially in terms of single-thread processor performance."
