With the continuous advancement of technology, the requirements for high-performance computing and graphics processing on memory bandwidth continue to increase. Today, the Solid State Technology Association (JEDEC) officially released the JESD239 GDDR7 memory standard, a new standard that takes memory bandwidth to a new level. JEDEC (Solid-State Technology Association) announced the launch of a new GDDR7 (Graphics Double Data Rate) memory standard that doubles the memory bandwidth of GDDR6 and delivers unprecedented performance gains for graphics processing and high-performance computing. Industry giants such as AMD and Nvidia have expressed their support for this new standard, heralding a technological revolution in the field of high-performance computing in the future.
The GDDR7 memory standard uses advanced pulsation amplitude modulation (PAM) connection** to double the bandwidth through high-frequency operation. PAM3 connection** improves the signal-to-noise ratio (SNR) for high-frequency operation, resulting in more stable and reliable data transmission, while also improving energy efficiency. The application of this technology has made a qualitative leap in the performance of the GDDR7 video memory standard, providing strong support for graphics processing and high-performance computing.
In addition to doubling the bandwidth, the GDDR7 memory standard comes with a host of other advanced features. First of all, it adopts the core independent LFSR (Linear Feedback Shift Register) training mode, which improves the training accuracy and reduces the training time through eye masking and error counters. This feature makes the GDDR7 memory standard more efficient in practical applications and can quickly adapt to various complex environments.
Second, the number of independent channels in the GDDR7 memory standard has doubled, from 2 to 4 in GDDR6. This improvement makes data transfer more efficient, further improving overall performance. GDDR7 also supports densities from 16 Gbit to 32 Gbit, including support for 2-channel mode to double the system capacity. This feature enables the GDDR7 memory standard to significantly improve both capacity and performance, meeting the demanding requirements of the high-performance computing field for video memory.
In terms of data integrity, the GDDR7 memory standard has also made significant improvements. By incorporating the latest data integrity features, including on-chip ECC with real-time reporting (ODECC), data poisoning, error checking and cleanup, and command address parity with command blocking (CAPARRBLK), the GDDR7 memory standard meets the market's stringent requirements for reliability, availability, and maintainability (RAS). These features ensure stable performance in high-load and complex environments, providing a solid guarantee for graphics processing and high-performance computing.
"The JESD239 GDDR7 marks a significant step forward in high-speed memory design," said Mian Quddus, Chairman of the Board of Directors of JEDEC. With the shift to PAM3 signaling, the memory industry has a new way to extend the capabilities of GDDR devices and push forward the evolution of high-performance applications. This statement speaks volumes about JEDEC's confidence and expectations for the GDDR7 memory standard.
At the same time, industry giants such as AMD, Micron, NVIDIA, Samsung, and SK hynix have also expressed their support for this new standard. These companies are leaders in the field of high-performance computing, and their support will undoubtedly accelerate the adoption and adoption of the GDDR7 memory standard. It is reported that Samsung and Micron have formulated a development plan for the next generation of GDDR7 modules, with the goal of achieving 32 Gbps speed and 24 GB+ 32 Gbps chips, respectively. These plans bode well for the GDDR7 memory standard in the future.
For consumers, the release of the GDDR7 memory standard means they will be able to enjoy a smoother, more efficient graphics and high-performance computing experience. Whether they're gaming, editing, or doing scientific research, the GDDR7 memory standard will give them even more power.
Overall, the release of the GDDR7 memory standard is a major breakthrough in the field of high-performance computing. Not only does it take memory bandwidth to new heights, but it also comes with a host of other advanced features that power graphics processing and high-performance computing. With the support of industry giants such as AMD and NVIDIA, as well as the active promotion of Samsung, Micron and other companies, we have reason to believe that the GDDR7 video memory standard will shine in the future market and bring users a better experience.
