SK hynix has just announced the introduction of its GDDR7 graphics memory, which it claims is the "industry’s best GDDR7." Offering 32 Gbps operating speeds, it performs 60% faster than current-generation GDDR6 memory which is limited to around 24 Gbps. It also promises a 50% improvement in power efficiency, potentially reducing the power requirements and heat generated by next-generation graphics cards that will use this new memory.
The company was able to achieve this jump in power efficiency by using new packaging techniques. For example, it increased heat dissipating substrate layers by 50% (from four layers to six), allowing the chip to release its built-up thermal energy much faster without increasing the PCB area it uses.
