DDR4 and DDR5 in mobo?

I'm looking at building a pc and I know that DDR5 is newer, but not sure what it means.

Are you sure you have your numbers correct?

ddr6 is supposed to be announced sometime q1 of this year, see if you can wait a bit

ddr4 is for ram sticks

and ddr5 is for video card memory


so likely you'll be looking for ddr4 mobo as ddr3 is last gen.

Just remember seeing some components with DDR4/5. Wasn't sure if they all could be different. Thanks.

"DDR4 is a memory standard that is similar in many ways to DDR3 but is, importantly, INCOMPATIBLE with DDR3. There were a few architectural improvements intended to solve issues seen at the higher speeds, and features added (e.g. support for post-package repair), but primarily the advantages are support for faster speeds (2133 MHz and up) and lower power. The real beneficiaries of the DDR4 transition are data centers. While you as an individual may eek out a little longer battery life with DDR4 in your laptop, a data center with hundreds of thousands of DIMMs will see a very substantial energy cost savings.

There are two DDR5’s. There has been a graphics DDR5 memory (GDDR5) for video cards on the market for a number of years. The other is the upcoming general DDR4-replacement whose definition is just being finalized and that won’t be mainstream for a few more years. The general DDR5 will probably debut in most systems at 3200 MHz and up, and will gradually replace DDR4 across a number of years."
