Question: what is the difference between the pixel 3 and the pixel 3 a?
Answer: Simply put, the Pixel 3 has a Qualcomm Snapdragon 845, a flagship-class Android processor (even if it is last year's model). The Pixel 3A has a Snapdragon 670 chipset — it's good, but it's not the best, and the Pixel 3 will be faster to launch apps, load webpages, and process more effect-laden pictures.
