I haven't written my comment in the spirit of entering a competition of who can get more RAM, but in the spirit that the Phoronix benchmark compares completely different computers, one with 8GB, the other with 16GB of RAM and gives a title suggesting that it's a comparison between chips, when the chip with 8GB isn't limited to 8GB. They could have gone for the 16GB option and made the comparison more honest. The chip doesn't have any such limitation.

The apps they use for comparison are limited by the CPU performance not memory size, so 8/16 shouldn't matter here. Unless you can point at something that's likely losing due to swapping?
