As you peruse the product specifications, in addition to screen size and resolution, you may see references to the device's processor speed (how fast that tablet makes calculations) and its amount of RAM or memory (how much data it can handle at once). Both these specs affect the overall performance of your tablet, but they don't make great benchmarks for comparing one tablet to another. That's because processing power is hard to parse: Each manufacturer tends to use a different processor, or CPU, and to give it its own confusing label. At the very least, you can use the CPU spec to compare tablets in the same range. (For example, in Apple's iPad range, the A10X beats the A9.) If you narrow down your choice to two or three tablets, a quick online search should give you some indication of how their processors stack up. As for memory, while more RAM is always better, it's not the only factor that affects performance. The quality of the components and the efficiency of the internal engineering also affect a tablet's speed. So we'd suggest making a note of the CPU and RAM specs without giving them too much weight in your final decision. The price of the tablet is usually a good shortcut to work out whether you're getting a speedy or sluggish device, and of course, online reviews can always help.
