Introducing Samsung 24GB GDDR7 DRAM For AI Computing

24GB GDDR7 DRAM

Future AI Computing: Samsung Launches 24GB GDDR7 DRAM. It sets the standard for graphics DRAM with its industry-leading capacity and performance of over 40Gbps.

First 24-gigabit (Gb) GDDR7 DRAM from memory pioneer Samsung was revealed today. Next-generation applications benefit from it’s speed and capacity. Data centers, AI workstations, graphics cards, gaming consoles, and autonomous driving will employ the 24Gb GDDR7 because to its high capacity and excellent performance.

“By introducing next-generation products that meet the expanding demands of the AI market, it will maintain to leadership position in the graphics DRAM market.” The 5th-generation 10-nanometer (nm)-class DRAM used in the 24Gb GDDR7 allows for a 50% increase in cell density while keeping the same package size as the previous model.

The industry-leading graphics DRAM performance of 40 gigabits per second (Gbps), a 25% increase over the previous iteration, is achieved in part by the advanced process node and three-level Pulse-Amplitude Modulation (PAM3) signaling. The performance of it may be further improved to 42.5 Gbps, contingent on the environment in which it is used.

Applying technology previously used in mobile devices to graphics DRAM for the first time also improves power efficiency. Power efficiency may be increased by more than 30% by reducing needless power use via the use of techniques like dual VDD design and clock control management.

The 24Gb GDDR7 uses power gating design approaches to reduce current leakage and increase operational stability during high-speed operations.

Major GPU customers will start validating the 24Gb GDDR7 in next-generation AI computing systems this year, with intentions to commercialize the technology early the next year.

GDDR6 vs GDDR7

Compared to the current 24Gbps GDDR6 DRAM, GDDR7 offers a 20% increase in power efficiency and a 1.4-fold increase in performance.

Today, Samsung Electronics, a global leader in cutting-edge semiconductor technology, said that it has finished creating the first Graphics Double Data Rate 7 (GDDR7) DRAM in the market. This year, it will be first placed in important clients’ next-generation systems for validation, propelling the graphics market’s future expansion and solidifying Samsung’s technical leadership in the industry.

Samsung’s 16-gigabit (Gb) GDDR7 DRAM will provide the fastest speed in the industry to date, after the introduction of the first 24Gbps GDDR6 DRAM in 2022. Despite high-speed operations, new developments in integrated circuit (IC) design and packaging provide more stability.

With a boosted speed per pin of up to 32Gbps, Samsung’s GDDR7 reaches a remarkable 1.5 terabytes per second (TBps), which is 1.4 times that of GDDR6’s 1.1 TBps. The improvements are made feasible by the new memory standard’s use of the Pulse Amplitude Modulation (PAM3) signaling technique rather than the Non Return to Zero (NRZ) from earlier generations. Compared to NRZ, PAM3 enables 50% greater data transmission in a single signaling cycle.

Notably, using power-saving design technologies tailored for high-speed operations, the most recent architecture is 20% more energy efficient than GDDR6. Samsung provides a low-operating voltage option for devices like laptops that are particularly concerned about power consumption.

In addition to optimizing the IC design, the packaging material uses an epoxy molding compound (EMC) with good thermal conductivity to reduce heat production. Compared to GDDR6, these enhancements significantly lower heat resistance by 70%, ensuring reliable product performance even under high-speed operating settings.

GDDR7 Release Date

According to Samsung, commercial manufacturing of their 24GB GDDR7 DRAM is scheduled to begin in early 2024. Although the precise public release date is yet unknown, this year’s certification process with major GPU manufacturers is already under way. With the availability of next-generation GPUs that will support the new memory standard, GDDR7 DRAM is now expected to be readily accessible in the market by 2024.
