Better without dedicated GPU - The Dell Inspiron 14 3493 in Review
Dell's 14-inch laptop is powered by a Core i7-1065G7 processor and a GeForce MX230 graphics chip. While the CPU performs well and offers enough performance for office workloads and web browsing, the GeForce GPU disappoints. Its clock speed begins to fluctuate after a short time. Thus, playing games is not possible. The only sensible use case for the GPU are applications that only stress it briefly.
For most prospective buyers, an Inspiron model without a dedicated GPU is likely a better choice. While the integrated Iris Plus Graphics G7 GPU cannot fully exhaust its capabilities either, it is able to deliver consistent performance, which makes gaming at least somewhat possible - provided the RAM is running in dual-channel mode.
