NVIDIA is now using SK hynix GDDR7 memory chips on its GeForce RTX 50 series GPUs

NVIDIA has reportedly started using GDDR7 memory modules from SK hynix, with the first GPU of choice being the mid-range GeForce RTX 5070.

In a new post on X by leaker "MEGAsizeGPU" we're hearing that NVIDIA has started shipping GeForce RTX 50 series "Blackwell" GPUs with new SK hynix GDDR7 memory modules, marking a change from using fellow South Korean company -- Samsung -- and its GDDR7 memory chips on RTX 50 series GPUs shipped so far.

SK hynix has been providing the best of the best in the HBM industry with its HBM3 and HBM3E memory chips for NVIDIA's dominant H100, H200, and new B200 AI GPUs and AI servers. SK hynix is also close to mass production of its next-gen HBM4 and HBM4E memory, expected to debut on NVIDIA's next-gen Vera Rubin AI platform in 2026.

TechPowerUp's W1zzard discovered that inside of multiple GeForce RTX 5080 16GB graphics cards were Samsung "K4VAF325ZC-SC32" GDDR7 units, while the rest of the RTX 50 series GPUs use 28Gbps GDDR7 memory modules from Samsung. We should expect those tides to change, with SK hynix now stepping in and providing GDDR7 memory modules for its consumer-focused GeForce RTX 50 series GPUs, and not just its AI GPU business.

NVIDIA has an incredible amount of control over who it sources its memory chips from, using SK hynix for its AI GPU side (it's bread and butter) as they're the best at what they do (Micron and Samsung also make HBM memory chips as well as GDDR memory chips). This provides NVIDIA with the ability to source its GDDR7 memory chips from whoever can fab enough, have them stable enough for 28-32Gbps operation, and can continuously pump those chips out for RTX 50 series GPUs.

It appears SK hynix is now pushing its latest GDDR7 memory chips enough that they're getting traction inside of the RTX 5070 for now, but I'm sure that's going to change in the weeks and months ahead and we'll see more SK hynix GDDR7 memory modules inside of more RTX 50 series GPUs.
