Samsung's first GDDR7 display memory has been developed: the speed can reach 32Gbps, up to 40%

CTOnews.com July 19, Samsung Electronics announced today that it has completed the research and development of its industry's first GDDR7, which will first be validated on the next-generation systems of major customers this year.

Samsung said that after Samsung developed a GDDR6 16Gb with a speed of 24 gigabits per second (Gbps) in 2022, the GDDR7 16Gb product will provide the highest speed 32Gbps of Samsung's video memory so far. At the same time, the innovation of integrated circuit (IC) design and packaging technology improves the performance stability at high speed.

CTOnews.com with Samsung GDDR7 introduction as follows:

The Samsung GDDR7 achieves an excellent bandwidth of 1.5 terabytes per second (TBps), which is 1.4 times that of the GDDR6 1.1TBps, and each data I / O (input / output) port rate can reach 32Gbps. The product uses pulse amplitude modulation (PAM3) signal mode to replace the non-return-to-zero (NRZ) signal mode of previous generations, thus achieving a significant improvement in performance. In the same signal period, PAM3 signal mode can transmit 50% more data than NRZ signal mode.

In addition, GDDR7 is designed to use energy-saving technology suitable for high-speed operation, which is 20% higher than that of GDDR6. Samsung offers a low-voltage option for power-intensive devices such as laptops.

In order to minimize the heating of video memory chips, in addition to integrated circuit (IC) architecture optimization, Samsung also uses epoxy molded compound (EMC) materials with high thermal conductivity in packaging materials. Compared with GDDR6, these improvements not only significantly reduce the thermal resistance by 70%, but also help GDDR7 achieve stable performance at high speed.
