Looks like I might have to skip DDR4 and jump to DDR5. No rush to upgrade CPU.

We heard this double density bs before what they need to do is work on better IMC to Handle this memory not just Bare minimum Requirements actually Over Engineer this so it'll last as they just pump more speed into these instead of density like they promised with DDR 4.

Personally, I think JEDEC should sue Rambus for creating a stock and calling it "DDR5" when they have not yet finalized the specifications of the standard and trying to force a certain set of specifications by creating real world products against the JEDEC subcommittee. This is the exact same BS that just happened with PCI-E 4, where the spec is partly finalized and 1-2 companies that are a part of the official subcommittee make some working stuff and call it PCI-E 4, and then hold up the rest of the process for years and years and years until the rest of JEDEC finally just gives in and says "fine the spec will be your product". Now this happening a second time is just going to start off every subcommittee having this issue as companies strong arm their way.

This would only work if DDR5 is physically compatible with existing DDR4 slots.

Same goes for PCI-E 4. Which may require extra traces on the motherboard, or some such.

We'll see what happens, though.

A couple of things....

Extra traces on the Mobo? Easily done on a new series/chipset.

New memory form factor? JEDEC isn't dropping it, so that is out the window. In a World where they did? Again, new motherboard handles that just fine.

Nothing we are discussing is dependent upon the AM4 socket itself. Just what controller is baked into the CPU and what is on the board outside of the socket.

It sounds like DDR4-8400 MT/s possible on the 8700K ( if dram manufacturers were to use the latest process nodes for DDR4 )

DDR3 had 40nm and later 30nm so they could still make a die shrink before the new generation.

There's not even that big of a real world performance differrence btw DDR3 1600 and DDR4 4000 anyway

If the cpu supports both standards, it's just a matter of choosing the motherboard with what you need.

 

Right now I'm using a g4560 with ddr3 as Skylake/Kaby Lake has a controller for both ddr3 and ddr4.

I have i7 920 with ddr3 memory. I was thinking of upgrading to ryzen as soon as ram prices go down, but now I think my PC can wait for an upgrade until 2020 biggrin.gif
