Memory War: Single VS Dual Channel for GAMING | Does it Matter?

Using the T730 lately has gotten us thinking a lot about single channel vs. dual channel for gaming…

Dedicated graphics have their own memory, so system RAM speed doesn’t affect GPU benchmarks much. As long as your CPU isn’t horribly underpowered, the GPU remains the bottleneck and it doesn’t care about your RAM speed. Pairing an i7 8700K with a GTX1060 is a cute cherry on top here.

It’s gonna make a significant difference for gaming on iGPUs with shared RAM, as well as games with lots of AI and physics + non-gaming CPU-intensive stuff like VeraCrypt(which has a built-in benchmark), Handbrake etc.

I’d be very interested to see if there’s any visible difference in star swarm stress test on that overpowered CPU test rig, since it’s a simulation rather than a canned GPU benchmark.

I got a Ryzen 3 APU in. If we have time, I’ll do some of those benchmarks again on it.

Please also include a test of Valley on APU+GTX1060.
Since it’s purely a GPU benchmark, I expect it to perform very similar (in terms of single vs dual channel performance) to i7+1060 and very different from just APU.

The more interesting test would be a simulation like star swarm, since it actually uses the CPU (and therefore system RAM) for a lot more than loading files.
