Choosing the best RAM
The best RAM for any CPU depends on official support by the chip, what you plan on doing with the PC, and how much you’re willing to spend. 13th Gen processors like the Intel Core i9-13900K support DDR4 RAM up to speeds of 3200MT/s or DDR5 RAM at up to 5600MT/s, though using XMP can overclock RAM modules with even faster results.
If you’re after the absolute best performance for your PC, you’ll want to consider the best DDR5 RAM. You shouldn’t notice too much of a difference to DDR4, at least in real-world results, especially when a capable GPU is used. The price of DDR5 continues to drop, but you can find some excellent deals on older DDR4. DDR4 does cost less overall, but you’ll have the trade-off in using older gen hardware.
