Gaming on 8GB vs. 16GB

Note that all of our X99 platform tests were conducted with 32GB, but we had a hunch that 32GB wasn't actually giving the system a boost. So we repeat the results from the Z170 platform on the previous page using a 2x8GB DDR4-3200 configuration, but add in a 2x4GB configureation running at the same speed to see whether we could draw out a difference between these two dual channel configurations. Note that running a single stick is destructive to performance and should never be done on the Z170 platform, or the X99 platform for that matter.

Nothing to see here, the Physics and Combined score are identical. The slight differences in the other scores result only from minor fluctuations in video card performance.

Crysis 3

Crysis 3

Crysis 3 doesn't need more than 8GB of memory, and in this in-game run performs almost identically. Getting this kind of result when actually playing through a moving game world suggests there's a very consistent engine powering the game.

Battlefield 4

BF4

Battlefield 4's performance is close enough to be a draw. Impressive given that this is an in-game run! 

Ryse: Son of Rome

Ryse

We see a very slight boost in minimums, which we'll see in a few more games before we're done.

Grid Autosport

Grid

While Grid Autosport benefits from faster memory, it does not benefit from more of it.

Grand Theft Auto V

GTAV

There seems to be an ever-so-slight improvement in minimums, which as we've said before are more important than the average, especially at these low framerates.

The Witcher 3

Witcher 3

These results are a draw.

Rise of the Tomb Raider

ROTR

Our newest and most graphically-impressive game doesn't get a big boost from memory quantity, although we see minimums move up a notch.

Let's turn now to our summary results, which will allow us to draw some conclusions on the optimal DDR4 configurations for gaming on both Intel's mainstream and enthusiast platforms.
