DRAM performance testing

Hi, in this post I tested how StarCraft II performance scales for various DRAM profiles. I go into more details – comparing it to another memory benchmark, and finding how it affects the game simulation versus other CPU tasks.

It’s a follow-up on the previous StarCraft II performance testing.

Nice one. This generally matches memory scaling seen across a wide variety of software on Ryzen. I’d expect a much smaller difference when using a discrete GPU on Intel CPUs.

Good mention about memory usage, some people seem to think that SC2 performs badly on 8GB RAM.

Edit: Might be interesting to compare single vs dual channel on a laptop with iGPU.

Yep, there are a lot of things that would be interesting to test. But I don’t have access to those systems.

Back in WoL and HotS then I was playing SC2 with 3GB of RAM and it still worked fine.

I imagine Intel scaling won’t be THAT different. But all systems will behave differently. Faster CPUs will be generally more memory bottlenecked. And I’m guessing Infinity Fabric speed increase tied to memory speed won’t be that impactful in StarCraft II. Almost everything is running on a single core (or at least the same CCX), and so you won’t benefit from faster core-core communication.

Yeah, good point about the core-core comms.

At one point I had to use an old laptop with i3 + HD3000 graphics. Worked, but needed all the settings at minimum and clean Windows.
