Samsung Unveils GDDR7: A Breakthrough in Graphics RAM

The standout feature of GDDR7 is its impressive data transmission speed of up to 32Gbps per pin, a remarkable improvement over GDDR6’s 24Gbps per pin capability. This means that GDDR7 can achieve a staggering total data transmission rate of 1.5 Terabytes per second, a 40% increase compared to the 1.1 Terabytes per second achieved by its predecessor.

The secret behind this remarkable speed boost lies in the adoption of 3-level Pulse Amplitude Modulation (PAM3). This technology, also utilized in USB4 and Thunderbolt 5, has proven to be highly effective in enhancing data transmission rates. It is worth noting that GDDR6X, used in graphics cards like the NVIDIA RTX 3090 and 4090, uses the related PAM4 standard.

Apart from its speed enhancements, it also offers a notable 20% increase in power efficiency compared to GDDR6. Samsung has also developed a low-operating voltage version of the new standard, catering to power-constrained devices such as laptops. This will not only improve the performance of these devices but also extend their battery life, enhancing the user experience.

To tackle the heat issue that often accompanies high-speed RAM, Samsung has made significant improvements in the design of the GDDR7 package. The epoxy molding compound (EMC) encasing the RAM chips now boasts 70% lower thermal resistance than the EMC used in GDDR6 packages. This improvement enables more efficient heat dissipation, ensuring that the RAM operates at optimal performance levels without overheating.

Excitingly, Samsung plans to send out samples to its key customers later this year. By doing so, the company aims to facilitate the development of GDDR7-based devices by leading industry players. This strategic move is expected to drive innovation in the gaming, graphics, and high-performance computing sectors, where the demand for faster and more efficient RAM is continuously growing.

As key industry players start exploring the potential of GDDR7-based devices, we can anticipate a wave of exciting advancements in the coming months. Stay tuned for more updates on the remarkable capabilities of GDDR7 as it reshapes the landscape of graphics memory technology.


Pokdepinion: The introduction of GDDR7 marks a significant step forward in the world of graphics RAM technology. With its remarkable speed and enhanced efficiency, GDDR7 promises to unlock new levels of performance and creativity for graphics-intensive applications.
