GDDR6 DRAM delivers speeds up to 24 Gbits/s

Samsung Electronics has started sampling its 16-Gb graphics double data rate 6 (GDDR6) DRAM with 24 Gbits/s processing speeds. Claimed as an industry first, the 24-Gbits/s GDDR6 DRAM is built ON Samsung’s third-generation 10-nanometer-class (1z) process using extreme ultraviolet (EUV) technology. The 24-Gbits/s GDDR6 DRAM targets next-generation graphics cards (video graphics arrays), laptops, game consoles, as well as artificial intelligence-based applications and high-performance computing (HPC) systems.

The 24-Gbit/s GDDR6 is based on an “innovative” circuit design and a highly advanced insulating material (High-K Metal Gate or HKMG) that is said to minimize current leakage. It will deliver 30% faster speeds compared to the previous 18-Gbits/s product, according to Samsung.

In addition, the GDDR6 DRAM can transfer up to 1.1-terabytes (TB) of data, or about 275 Full HD movies, in one second, when integrated into a premium graphics card. It is fully compliant with JEDEC specifications.

The new GDDR6 portfolio will also feature low-power options that help extend the battery life of laptops. Using dynamic voltage switching (DVS) technology which adjusts the operating Voltage depending on performance requirements, the company will offer 20-Gbits/s and 16-Gbits/s versions with approximately 20% higher power efficiency at 1.1 V, compared to the 1.35-V GDDR6 industry standard, according to the company.

In addition to PCs, laptops, and game consoles, graphics DRAM also is extending into other graphics-intensive applications like HPC, autonomous driving, and electric cars, said Samsung. “Addressing these emerging markets, Samsung’s GDDR6 will enable seamless 4K and 8K video playback, while supporting demanding AI accelerator workloads.”

Samsung plans to commercialize the 24-Gbits/s GDDR6 DRAM in line with GPU platform launches.
