SK hynix GDDR7 memory in mass production this quarter
The company has sped up its plans.
SK hynix has confirmed that the mass production of GDDR7 memory will start much sooner than speculated. Previously, Anandtech reported that a company representative had said GDDR7 volume production would not begin until Q1 2025. However, the company quickly responded to these claims and confirmed that mass production will start sooner, in Q4 2024.
It seems the rumors have motivated SK hynix engineers to speed up the production of next-gen gaming memory. According to the latest press release, mass production will now start in the third quarter of 2024.
The development of GDDR7 in March comes amid growing interest by global customers in the AI space in the DRAM product that meets both specialized performance for graphics processing and fast speed. The company said that it will start volume production in the third quarter.

The company has confirmed that GDDR7 memory will feature speeds up to 32 Gbps , which is 60% faster than the current generation (GDDR6). SK hynix provided an example, stating that next-gen GPUs could achieve up to 1.5 TB/s of bandwidth (through 384-bit bus). Additionally, 40 Gbps chips are also expected, but it is clear these speeds will not be available anytime soon. In fact, rumors suggest that the GeForce RTX 50, the only graphics series known to feature GDDR7 so far, will use 28 Gbps speeds in its first generation.
Next-gen GDDR7 memory from SK hynix will also offer improved power efficiency by over 50% and will adopt new packaging technology. By increasing the number of layers in the heat-dissipating substrates from four to six and reducing thermal resistance by 74%, they have enhanced performance. What may also be worth noting is that the GDDR7 module size remains unchanged from GDDR6.
