If your main concerns are price and battery life, the Dell Inspiron 15 3511 may suit you as it's less expensive and has a decent battery. However, for higher performance, especially in gaming or demanding tasks like 3D modeling, machine learning, or intensive engineering software, the Razer Blade 14, with its superior processor and graphics, is preferable. The Razer Blade also boasts a higher resolution screen which is better for creative work, though it is more costly and can impact battery life. In terms of portability, both are similarly weighted, but the Dell has a larger screen while the Razer offers a more compact form factor. Give Feedback

PCMag
Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

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."
