"30GB Movies 50 Titles in 1 Second... Samsung Develops Highest-Speed GDDR7 DRAM"

Industry's Fastest 32Gbps GDDR7 DRAM Developed
Leading the Next-Generation Graphics DRAM Market

Samsung Electronics has succeeded in developing next-generation graphics DRAM that increases data processing speed to handle 50 UHD movies with a capacity of 30GB (gigabytes) in just one second. The company aims to further increase its market share in the graphics DRAM market with industry-leading speed and power efficiency.

On the 19th, Samsung Electronics announced that it has developed the industry's first ‘32Gbps GDDR7 (Graphics Double Data Rate) DRAM,’ which will lead the growth of the next-generation graphics market. This achievement comes just one year after developing the industry's first 24Gbps GDDR6 DRAM. GDDR DRAM is essential for fields that require rapid processing of vast amounts of data, such as graphics, data centers, and artificial intelligence (AI). It has more channels for data transmission and higher bandwidth compared to general DDR. Samsung plans to begin product verification within this year by integrating the newly developed 32Gbps GDDR7 DRAM into next-generation systems of key customers.

The newly developed product features significantly enhanced high-performance and low-power characteristics. Compared to previous models, data processing speed has increased by 1.4 times, and power efficiency has improved by 20%. The ability of the new product to achieve the industry's highest speed of up to 32Gbps per data input/output pin is largely due to the newly applied ‘PAM3 signaling method.’ The PAM3 signaling method distinguishes signals as ‘-1,’ ‘0,’ and ‘1,’ transmitting 1.5 bits of data per cycle, which allows 1.5 times more data to be transmitted in the same signal cycle compared to the existing NRZ method (which distinguishes signals as ‘0’ and ‘1’ and transmits 1 bit of data per cycle).

Accordingly, when the ‘32Gbps GDDR7 DRAM’ is mounted on a graphics card, it can process up to 1.5TB of data per second (a speed capable of processing 50 UHD movies with a capacity of 30GB in just one second). This represents a 1.4 times performance improvement compared to the 24Gbps GDDR6 DRAM developed in July last year, which provided up to 1.1TB.

Samsung Electronics applied low-power design technology optimized for high-speed operation, improving power efficiency by 20%. In particular, an option supporting ultra-low voltage is provided for products where low power consumption is critical, such as laptops. Additionally, Samsung applied a new material with high thermal conductivity to the EMC package (semiconductor circuit protector) and optimized circuit design to minimize heat generation caused by high-speed operation. As a result, the temperature change per watt (W) compared to existing GDDR6 has decreased by about 70%, enabling stable quality even during high-speed operation.

This new product can be widely used not only in general IT devices such as PCs, laptops, and game consoles but also in various fields requiring ultra-high-speed large-capacity data processing technology, including next-generation high-performance computing (HPC), artificial intelligence (AI), virtual reality, and autonomous vehicles. In particular, with the expansion of autonomous driving systems and the advancement of in-vehicle infotainment systems such as high-resolution maps, video streaming, and high-spec games, expectations for utilization in the automotive sector are high.

Byoung-chul Bae, Vice President of the Memory Product Planning Team at Samsung Electronics, said, "‘GDDR7 DRAM’ will provide a more differentiated user experience in applications requiring excellent graphics performance," adding, "We will commercialize it in a timely manner to meet the demand in the premium graphics market and continue to lead the next-generation graphics DRAM market." According to global market research firm IDC, as of the end of last year, Samsung holds 48% of the global graphics DRAM market share, followed by Micron with 26% and SK Hynix with 26%.
