GDDR6X memory comes with a revolutionary design that significantly increases the data transfer speed.
The new feature is called PAM4 or Pulse Amplitude Modulation 4.
Traditionally the transmissions to and from memory operate in a system with two power levels 1 and 0.
This is despite GDDR6X having 50% extra bandwidth compared to GDDR6.
The disparity between bandwidth increases and power efficiency improvements, however, means that overall power requirements have increased.
This does help keep costs and thermals down though.
