WCCF always goes off the rails with some shit."It should also be pointed out that high-end Navi GPUs might retain High-Bandwidth memory design like the current flagship. While AMD is featuring GDDR6 memory on their mainstream RDNA based cards, it is likely that the company would go ahead with the newer HBM2E VRAM.
The HBM2E DRAM comes in 8-Hi stack configuration and utilizes 16 Gb memory dies, stacked together and clocked at 3.2 Gbps. This would result in a total bandwidth of 410 GB/s on a single and 920 GB/s with two HBM2E stacks which is just insane. To top it all, the DRAM has a 1024-bit wide bus interface which is the same as current HBM2 DRAM. Samsung says that their HBM2E solution, when stacked in 4-way configuration, can offer up to 64 GB memory at 1.64 TB/s of bandwidth. Such products would only be suitable for servers/HPC workloads but a high-end graphics product for enthusiasts can feature up to 32 GB memory with just two stacks which is twice as much memory as the Radeon VII."
AMD would be foolish to again make the mistake of using super expensive memory that gives them no advantage, and fucks up their pricing schemes.
