Discussion on consumer hardware progression

[unwind-protect]

RAM speed has very little impact on most things that consumers do. Even among engineering applications and friends only some do (see phoronix).

For gaming the x3d cache is the better solution anymore.

The cost for more channels would be enormous. Bigger mainboards, bigger sockets, probably more layers, more pins on the CPU etc pp

X58 had triple channel partially to increase totalRAM amount, not speed, via having 6 slots. With 48 and 64 UDIMMs now that isn't a necessity for consumers now.

As for other replies on slot count and board cost, I don't see why you NEED to add more slots for more channels, just make them 1dpc instead of 2dpc. Wouldn't that help with latency too?

You need to define DPC to make sure all are on the same page. It means different things to different people - even within the realm of computing.

For me, it typically means Deferred Procedure Call, which is an OS technique and not the same thing as additional channels configured in and requiring additional hardware. DPC can improve performance but those gains should not be compared to the potential gains actual channels and additional sticks provide.

I see the advantages of DPC as similar to those achieved by hyperthreading in a CPU: a method to simulate additional CPU cores without actually having additional cores. It does improve performance in some scenarios, but typically not as much as more physical cores - or as much as the marketing hype wants us to believe.

Interesting... to me, DPC means DIMMs per channel. Maybe what was mean is that with 1 DIMM per channel, you can make a 4-channel motherboard with 1 DIMM each instead of a 2-channel with 2 DIMMs each?

Which illustrates my point that we need the OP to define what he meant. Folks should not use acronyms unless they first define them since almost all have multiple meanings.

Deferred Procedure Call - Wikipedia

I note the most common definition (at least in my universe) is Data Processing Center. But I assumed the OP (er... ummm, "O"riginal "P"oster in his OP ("O"pening "P"ost) didn't mean that one.

What consumer application needs more than 100GB/s bandwidth obtainable with DDR5 7000+? The reality is pretty much all use cases for consumer been conquered with hardware available even 5 years ago.

Just edge case stuff like high 240hz+ gaming or 4k 120hz even needs the latest hardware now. Upgrading largely pointless for most. Not just in PCs as well, phones and other tech is similar. Nothing on the consumer end that's a big jump, all meh.
