GDDR7 Is Coming

In the video, the host explains that the next generation of video memory, GDDR7, is expected to bring a substantial upgrade in bandwidth, addressing common bottlenecks where high resolution textures and complex visual effects strain GPU memory. The discussion emphasizes that this upgrade aims to deliver never before seen bandwidth without a corresponding spike in power draw, which could be a turning point for enthusiasts who want to push settings higher without hitting thermal or power limits. The host puts the potential gains into perspective by comparing current memory bandwidth on GPUs like the RTX 4080 with what GDDR7 could achieve through wider memory buses and improved encoding schemes, suggesting a dramatic throughput increase that could improve real-world gaming performance even if the VRAM amount remains similar. The segment also delves into the technical underpinnings of GDDR7, including how PAM3 and potential NRZ modes contribute to efficiency and speed, while acknowledging that the exact “secret sauce” will depend on future hardware design choices and controllers. Viewers are left to anticipate late 2024 for the first major GPU refreshs from major vendors and rumors that Nvidia’s upcoming RTX 5000 series might adopt GDDR7, with the host humorously noting personal purchase plans contingent on budget realities.
