Even with consoles iterating on a regular cadence, . This is typically due to innovations that change how computer graphics work, and that is happening right now with . The RTX 3070, 3080, and 3090 use . This is a step above the traditional GDDR6 VRAM, and it could represent a generational leap forward in system-bandwidth performance thanks to Micron’s PAM4 tech.
Pulse amplitude modulation (PAM4) is the name for pushing 2 bits of data over a connection instead of 1 bit. It’s a technical concept, but essentially, this enables the system to call from 4 potential states instead of 2 with each burst of information. With PAM4, Micron and Nvidia are promising a significant boost to I/O data rates and bandwidth. GDDR6X is also
