What is the impact of memory speed on system performance?
The system supports various bus speeds and module types, with different compatibility levels for throughput. The presence of certain module sizes aligns better with specific bus widths, but it doesn’t necessarily affect RAM size requirements. It’s worth considering whether matching module sizes to the bus type is important for performance or just a design preference. There may be minor benefits for some applications, but overall it seems unnecessary unless targeting particular hardware constraints.
System ram and VRAM belong to distinct platforms, languages, or architectures. The GPU's memory is controlled by its architecture (die), while the RAM in your motherboard's slots is managed by the integrated controller on the CPU die—previously called NorthBridge if you're familiar with technology from over two decades ago.
Choose ram based on your workloads and requirements. On DDR5 platforms, consider tight latency, dual channel DDR5-6000MHz (or slightly faster). For Ryzen systems, opt for modules featuring AMD's E.X.P.O. If using Intel, look for Intel's X.M.P advertised on the product.
I believed I had come across information about combining GPU with system RAM, especially for AI systems. I was considering shared or coherent memory in the M2Ultra computer. I was hoping it would eventually appear in regular computers and had imagined this idea in my mind. I’m curious if there’s any possibility of it becoming available soon. I haven’t heard anything yet.

What does coherent memory mean on a GPU?
I came across the terms "non-coherent" and "coherent" memory without ever seeing them in tech papers about graphics programming. I kept looking for a straightforward explanation but kept finding...
The question posed seems to be a mix-up. What has been discussed is about integrated graphics using system RAM for VRAM, which is not new and has been around for years.
They are developing a new AI version. I'm uncertain if it will reach standard desktop PCs in the coming years. It's more sophisticated than typical shared memory for integrated graphics.
You might be considering DRAM cache, which has already occurred. It involves placing fast memory close to the CPU, but it's less expensive than creating more SRAM. It's possible that NPUs will require their own memory or cache to function better, or they may continue integrating to provide DMA capabilities.
Integrated DRAM or HBM on the physical CPU package is not new. Both AMD and Intel have implemented this approach, often in a single chip.
We are nearing a point where memory will be removed from the CPU cores as a separate layer. The stack will include the CPU, L1, L2, L3/X3D/l4, DRAM cache/HBM, System Memory, and Storage.
