What is the difference between the Iconia models A1-840-131U and A1-840-18N3? The listed specs are the same, but a $50 price difference means something is different.

So what’s the difference between DDR3, DDR3L and LPDDR3? I get that question a lot, and there are a lot of differences. I have summarized some of the key differences in the table below. The short summary is, LPDDR3 is more expensive but has much lower standby power and a better form factor for mobile devices; while DDR3 and DDR3L are less expensive and consume more power but are more suitable for larger memory arrays found in PCs and servers.
