Jedec has officially announced GDDR7 as the next-generation memory standard, an exciting change in the graphics and high-performance computing markets. The addition of AMD and NVIDIA, as well as the development plans of memory manufacturers such as Samsung and Micron, bodes well for the next generation of memory technology to enter the market soon, bringing unprecedented performance gains to users.
Judging from the published standards, GDDR7 has a significant improvement in bandwidth, speed, and density. It has twice the bandwidth of GDDR6, up to 192 Gbits per device, supports densities from 16 Gbit to 32 Gbit, and also supports dual-channel mode to double the system capacity. This means that the new generation of graphics cards will be able to handle more data and more complex graphics tasks, resulting in a smoother and more realistic visual experience for users.
In addition, with the shift to PAM3 signaling, GDDR7 not only focuses on bandwidth improvement, but also meets the needs of the RAS market by incorporating the latest data integrity features. This will help ensure the accuracy and reliability of the data, reduce the error rate, and improve the overall performance of the system.
Judging from the current situation, the RTX 50 series flagship card is expected to be the first batch of graphics cards equipped with GDDR7 video memory. According to the news, the performance improvement of the new card is very significant, nearly double the performance of the previous generation. This will undoubtedly allow NVIDIA to continue to maintain its leading position in the high-performance graphics card market.
Assuming a 384-bit bit width, the bandwidth of 32GHz GDDR7 will have an average of 18TBS, which is a full 82 ahead of the RTX 4090 and almost double that of the RX 7900 XTX.
In contrast, AMD doesn't seem to have a product that can directly compete with Nvidia's flagship cards such as the RTX 5090. Although AMD has made some progress in the graphics card market in recent years, it still needs to keep working and improving in the field of high performance, especially in the face of a strong rival like NVIDIA.
Overall, the launch of GDDR7 will push the high-performance computing market into a new stage of development. We look forward to seeing more products with this new technology to deliver even better performance and experience to our users." At the same time, it is also expected that AMD and other manufacturers can catch up in the competition of next-generation video memory technology and provide consumers with more choices and better products.
