SK Hynix to Start Mass Production of GDDR7 Chips in 2025

TapTechNews June 12th news, according to foreign media Anandtech report, representatives from SK Hynix stated at the 2024 Taipei International Computer Show that the company will start large-scale production of GDDR7 chips in the first quarter of 2025.

SK Hynix displayed GDDR7 video memory at COMPUTEX 2024 and confirmed that relevant particles have been available for sampling to partners.

SK Hynix has simultaneously planned GDDR7 video memory with capacities of 16Gb and 24Gb (Note by TapTechNews: that is, 2GB and 3GB per single chip). The equivalent rate can reach 40Gbps, and the single-chip bandwidth can reach 160GB/s (with a 32-bit video memory bit width).

GDDR7 adopts a brand-new PAM3 signal encoding technology and supports on-chip ECC and other data integrity functions. The single-chip video memory capacity can be up to 32Gb, and the equivalent rate can reach 48Gbps, which can better serve the game, computing, and AI markets.

In terms of the other two major video memory enterprises, Samsung Electronics launched information about 28/32Gbps rate GDDR7 video memory on its official website in March, both with a 16Gb capacity.

Micron also announced the sampling of its 16Gb capacity version of 32Gbps GDDR7 video memory earlier this month. Compared to its GDDR6 product, Micron's GDDR7 video memory overall data energy consumption decreased from 6.5pJ/bit to 4.5pJ/bit.

As for the application side, as reported earlier by TapTechNews, the leaked files from the hacker showed that Nvidia's mobile version of the RTX50 Blackwell graphics card is expected to fully adopt GDDR7 video memory.
