Question DDR5 5600 28-34-34-89 or 6600 32-39-39-76 ?

[dimar]

I'll be upgrading to 13900K. Was wondering if there's gaming comparison benchmarks between DDR5 5600 28-34-34-89 and 6600 32-39-39-76.
Can't seem to find any.

What motherboard?

The starting point is to verify that the motherboard will support the CPU and RAM being considered.

May be moot if the DDR5 specs are not supported.

Check both the motherboard's User Guide/Manual along with the manufacturer's website QVLs (Qualified Vendor's List) and FAQs.

And you could end up spending more for very little performance gain.

And also remember to keep in mind the GPU and overall power requirements. PSU?

Just my thoughts on the matter.

Also depends on the CPU's memory controller.
My current i9-12900K can't handle 6400 CL40. It's only stable at 6200 with basic tweaking. Hopefully 13900K or 13900KS can do better.
From the limited benchmarks I could find, it looks like 6600 is faster.

You can't really test RAM by itself in gaming tests. You have to test it with a CPU. And until someone does a memory scaling test with Intel's 13th gen, we'll never know which one performs good enough to get a more expensive kit.
