Samsung announced the release of the world’s first 24-gigabit GDDR7 memory chips. This memory features the highest capacity available today and speeds exceeding 40 Gbps, making it ideal for the high-performance accelerators of the future. Testing of the new product by major customers will begin this year, and mass production is planned for early 2025. It is very likely that this memory will be installed in the GeForce RTX 5090 and other new generation video cards.

The new solution from Samsung will find application not only in traditional areas – video cards, game consoles and autonomous driving systems, but also in data centers and workstations for AI. With high data transfer speeds and increased capacity, the new GDDR7 will be a key component for infrastructure that requires fast access to large amounts of information.
«Having developed the industry’s first 16 Gigabit GDDR7 last year, Samsung strengthens its technology leadership in the graphics DRAM market with this latest achievement,” said YongCheol Bae, executive vice president of memory product planning at Samsung. He also noted that the company will continue to release innovative products that meet the growing needs of the AI and high-performance computing industry.
The new 24Gbps GDDR7 uses fifth-generation 10nm-class DRAM to increase cell density by 50% without changing packaging dimensions. This significant technological advancement provides greater capacity and performance than previous solutions.
One of Samsung’s key technological advances is the use of three-level PAM3 pulse amplitude modulation, which allows it to achieve speeds of over 40 Gbps, which is 25% faster than the previous generation GDDR6. Depending on operating conditions, performance can increase up to 42.5 Gbit/s.
The energy efficiency of the new product has been significantly improved due to the introduction of technologies previously used in mobile devices, now used for the first time in graphics memory. The introduction of clock control techniques and dual-level power design (VDD) has significantly reduced power consumption, resulting in an increase in energy efficiency of more than 30%. This is especially critical for compute-intensive systems, where every percentage point in energy efficiency results in tangible benefits.
To ensure stable operation of GDDR7 at high data processing speeds, current leakage has been minimized through the use of new power management methods. This allows you to significantly reduce energy losses and increase system reliability even at maximum loads.
