Samsung Electronics developed the trade’s first 12-nano 24 gigabit (Gb) GDDR7 DRAM, focusing on functions in knowledge facilities and synthetic intelligence (AI) workstations, the corporate stated Thursday.
GDDR7, or Graphics Double Knowledge Fee 7, is a graphic DRAM, or dynamic random-access reminiscence, designed to spice up the efficiency of units like gaming consoles and graphic playing cards.
Based on the chipmaker, it plans to commercialize the brand new chip early subsequent yr, starting its validation for next-generation AI computing techniques for main GPU (graphics processing unit) clients inside this yr.
Samsung stated the brand new chip achieved main upgrades in capability, efficiency and energy effectivity from its predecessor 16Gb GDDR7, which the corporate developed final yr.
The 24Gb GDDR7 was produced by means of 12-nanometer class course of know-how, which enabled elevated cell density to attain the trade’s highest capability of 24Gb whereas sustaining the identical bundle dimension because the predecessor.
The brand new chip additionally makes use of three-level Pulse-Amplitude Modulation, or PAM3, signaling know-how to allow 40 gigabits-per-second of pace, which is a 25-percent enchancment over the earlier model. The GDDR7’s efficiency will be additional enhanced to as much as 42.5Gbps, relying on the utilization setting, the corporate stated.
Energy effectivity can be enhanced by 30 %, by making use of applied sciences that had been beforehand utilized in cell merchandise, comparable to clock management administration and twin VDD design.
Clock management administration know-how reduces energy consumption by guaranteeing that every circuit solely operates when crucial. Twin VVD design is an influence administration approach that lowers exterior voltage throughout low-speed operation.
“After growing the trade’s first 16Gb GDDR7 final yr, Samsung has strengthened its technological management within the graphics DRAM market with this newest achievement,” stated Bae Yong-cheol, govt vp of Reminiscence Product Planning at Samsung Electronics.
“We’ll proceed to steer the graphics DRAM market by bringing next-generation merchandise that align with the rising wants of the AI market.”

Together with high-bandwidth reminiscence (HBM) chips, that are making headlines for his or her use in AI processors, GDDR chips are additionally gaining consideration for his or her utility in AI providers.
HBMs are used for high-performing AI processors, as their bigger bandwidth permits transferring extra knowledge directly, though their switch pace is slower than comparable GDDR chips. Most AI servers for knowledge facilities use HBM-powered AI processors.
Nonetheless, HBMs require larger manufacturing prices and include much less flexibility for utility in comparison with GDDR Chips. It’s extensively identified that HBM chips price 3 times greater than basic DRAMs.
On account of these professionals and cons, each HBM and GDDR chips are anticipated to play complementary roles till prices for HBMs decline. HBMs are extensively used for high-performance chipsets used for AI studying, whereas GDDR chips are used for AI inference.
