In particular, Samsung plans to introduce 16-gigabit GDDR7 chips with a data transfer rate of 37 Gbps per pin. To achieve this performance, the new standard of graphics memory will use PAM3 pulse width modulation with three signal levels. By the way, GDDR6X, a joint development of Micron Technology and Nvidia, uses PAM4.
Unfortunately, the South Korean chipmaker has not yet disclosed the estimated timeframe for the start of mass production of GDDR7 chips. Foreign colleagues assume that the new memory standard will be used in Nvidia GeForce RTX 50-series (Blackwell architecture) and AMD Radeon RX 8000 (RDNA 4) video cards.
