We found the Patriot Viper doesn't overclock quite as far as the G.Skill, and as such the speeds are a little lower, however it's only very slight. Generally the Patriot memory performance is very good and at stock speeds it basically matches the G.Skill GT1s in everything but raw copy performance.
The Elixir memory is naturally lower performing as its timings are slower and the total overclock is a great deal less at just 1,750MHz.

Nanoseconds (lower is better)
In terms of latency, the Patriot memory performs where we expect it to, although the Vipers at 1,800MHz C8 are a nanosecond slower than the G.Skill GT1s at the same timings. Both use the same Samsung HCF0 memory chips, so the differences are likely a system variable rather than memory.
Naturally the Elixir memory sits lower down the table as it offers a slower latency and a limited overclock.

Copy (MB/s)
On the Asus Rampage Extreme the situation is a little different as the Patriot clearly tops the tables, although it's just by a small margin. The overclocked Elixir also shows good performance in read speeds, although it's fractionally slower in copy and write tests than the Corsair and G.Skill below it.

Nanoseconds (lower is better)
In terms of latency performance the Patriot is again at the top of the table by a nice few nanosecond margin, even tough it doesn't overclock quite as much. The Elixir sits at the bottom of the table as we'd expect, but it's again not a huge margin of difference, and when overclocked it's latency is actually surprisingly low.
