DDR5 Memory Performance Scaling with Alder Lake Core i9-12900K

DDR4 is readily available and has come down in pricing a lot in recent months despite the crisis and shortages. In applications, we see DDR4-3600 CL16 roughly on par with DDR5-4800, which is the lowest speed grade DDR5 announced at this time, so almost nothing is lost despite the numeric difference of "3600" vs. "4800" and huge price increase tied to it. In gaming, which is more sensitive to memory timings than memory bandwidth, our DDR4-3600 configuration works even better, achieving FPS similar to DDR5-5600. The takeaway here is to focus on DDR4 unless you absolutely want to play with the new DDR5 tech. Motherboards are cheaper, too, and you can use the DDR4 memory you already have.
