As can be seen in this excellent YouTube video, the process of replacing or upgrading RAM in a 2018 Mac mini isn't all that hard.
We might have definitive answers to two big questions relating to the new Mac mini and 2018 iPad Pro with regards to how their memory configuration works.
Here's a comparison between iPhone 7 with 2GB RAM Vs iPhone 7 Plus with 3GB RAM, showing the difference between the two devices with regard to RAM and memory management.
We now have almost 100% confirmation that the newly announced iPhone 7 Plus features 3GB of RAM within its minimally redesigned body. This confirmation comes following a few weeks of rumors about the said phone featuring 3GB of RAM.
