This has allowed each GDDR version to enhance the memory bus frequency, thereby increasing performance.
However, with frequency increases becoming complex, the industry is exploring other solutions.
With its reduced baud rate, PAM4 also significantly lessens signal losses.
GDDR7, however, will utilize PAM3 encoding, a compromise between PAM4 and NRZ signaling.
GDDR7 promises better performance than GDDR6, along with lower power consumption and implementation costs than GDDR6X.
In addition, GDDR7 offers ways to optimize memory efficiency and power consumption.
This includes four different read clock modes, allowing it to run only when needed.
GDDR7 memory subsystems can also issue two independent commands in parallel, optimizing power consumption.
