The Hotspot Engine Program The JEDEC Solid State Technology Association today announced the release of the new JESD239 GDDR7 SGam standard, which delivers twice the bandwidth of GDDR6 and up to 192GB s per device to meet the growing demand for more memory bandwidth in graphics, gaming, compute, networking, and AI applications.
GDDR7 is the first JEDEC standard DRAM to use a Pulse Amplitude Modulation (PAM3) interface for high-frequency operation, and its PAM3 interface improves signal-to-noise ratio for high-frequency operation while improving energy efficiency. By using 3 potentials, -1) to transmit 3 bits in 2 cycles, instead of the traditional NRZ (non-return-to-zero) interface transmitting 2 bits in 2 cycles, PAM3 provides a higher data transfer rate per cycle, resulting in improved performance.
The standard will bring a performance spike to graphics card manufacturers such as AMD, NVIDIA, and Samsung, especially the RTX 5090, which is expected to use the next-generation video memory GDDR7. The RTX 5090's performance boost is staggering, almost double that of the previous generation. With a 384-bit width, a GDDR7 bandwidth of 32GHz would be close to 18TBS, which is 80% ahead of the RTX 4090 and almost double that of the RX 7900 XTX.
In addition to the performance improvement, GDDR7 also has lower power consumption and higher stability, which is important for the heat dissipation and longevity of the graphics card. GDDR7 also supports ECC (Error Detection and Correction) to avoid data corruption and system crashes.
The release of GDDR7 has also sparked heated discussions and attention in the industry, with many experts and ** analyzing and evaluating its prospects and impacts. Here are some points to watch:
Wall Street**GDDR7 is an innovative technological breakthrough that will bring new impetus and opportunities to the development of graphics processors. The advent of GDDR7 also shows that there is still a lot of room for improvement in memory technology, and higher performance memory standards such as GDDR8 or GDDR9 may emerge in the future.
The New York TimesGDDR7 is a double-edged sword, which not only provides graphics card manufacturers with stronger competitiveness, but also brings consumers a higher choice. The high performance and quality of GDDR7 may put some consumers off, while others may be attracted to it, leading to fragmentation and confusion in the market.
FortuneGDDR7 is a revolution that will change the market landscape and the industry landscape of graphics processors. The introduction of GDDR7 will make the competition of graphics card manufacturers such as AMD, NVIDIA, and Samsung more fierce, and will also cause a huge impact and challenge to other graphics memory technologies such as HBM (High Bandwidth Memory) and GDDR6X.
"Science and Technology**".GDDR7 is an advanced memory technology that will provide enhanced support and security for graphics, gaming, computing, networking, and AI applications. The emergence of GDDR7 also reflects China's progress and contribution in the field of microelectronics, and China's SK hynix is one of the formulators of the GDDR7 standard and one of the main producers of GDDR7.
