What is GDDR7?
GDDR7 is the latest generation of high-speed memory specifically designed for graphics processing units (GPUs). It’s the successor to GDDR6 and GDDR6X, promising significant improvements in performance and efficiency.
What Makes GDDR7 Special?
Incredible Speed: GDDR7 is notably faster than its predecessors. It achieves this by employing PAM3 (Pulse Amplitude Modulation 3) signaling, which allows for more data to be transmitted in each signal cycle. This translates to smoother gameplay, higher frame rates, and better overall performance in graphics-intensive applications.
Enhanced Efficiency: Despite the significant speed boost, GDDR7 is also more energy-efficient. This is crucial for both desktop and mobile devices as it helps to prolong battery life and reduce heat generation.
Improved Reliability: GDDR7 boasts better thermal resistance compared to previous generations. This means it can handle higher temperatures without compromising performance, making it more reliable and durable.
In essence, GDDR7 represents a major leap forward in graphics memory technology. It’s poised to power the next generation of gaming consoles, graphics cards, and other high-performance devices, delivering stunning visuals and smooth performance.
Samsung’s GDDR7:
Samsung’s GDDR7 graphics RAM is designed to push the boundaries of data transmission rates. It achieves an impressive 32Gbps per pin. This translates to a total bandwidth of 1.5 Terabytes per second.
This is a substantial improvement over GDDR6. GDDR6 maxes out at 24Gbps per pin and 1.1 Terabytes per second.
The secret behind this speed boost lies in the adoption of 3-level Pulse Amplitude Modulation (PAM3). This modulation technique is also utilized in cutting-edge technologies like USB4 and Thunderbolt 5.
While GDDR6X, found in high-end GPUs like the Nvidia RTX 3090 and 4090, uses PAM4, GDDR7’s implementation of PAM3 offers a balanced approach. It enhances data rates efficiently.

Advanced Thermal Management
Heat management is a critical aspect of high-performance memory chips, and Samsung has made significant strides in this area with GDDR7.
The company has introduced a new epoxy molding compound (EMC) for encasing the RAM chips. This new EMC boasts 70% lower thermal resistance compared to the material used in GDDR6 packages.
The improved thermal conductivity ensures that heat is dissipated more efficiently, keeping the chips cooler and enhancing overall performance and longevity.
Industry Impact and Availability
Samsung’s GDDR7 is poised to have a significant impact on the graphics memory market. The increased speed and efficiency make it an ideal choice for high-performance computing applications, including gaming, professional graphics, and data-intensive tasks.
With its enhanced thermal management, GDDR7 also addresses one of the critical challenges in high-speed memory design.
The company plans to send out samples of GDDR7 to its key customers later this year. This will enable device manufacturers to start developing and testing GDDR7-based products, paving the way for the next generation of high-performance computing devices.
