GeForce RTX 5070 becomes second consumer model to feature 3GB GDDR7 modules
This was not a mistake.
The 12GB GeForce RTX 5070 Laptop GPU was a long-expected update after several laptop listings already pointed to such a configuration. We reported in March that ASUS and Lenovo product pages briefly listed RTX 5070 Laptop systems with 12GB of GDDR7 memory, although NVIDIA had not confirmed the model at the time. More recently, MSI also teased such a model in their new laptop.
NVIDIA is now confirmign these rumors and leaks and they are adding a new GeForce RTX 5070 Laptop GPU configuration with 12GB of memory . The existing 8GB variant is not being replaced. T he company says this gives partners more options while memory supply remains constrained.
GeForce RTX 5070 Laptop GPU With 12GB
Demand for GeForce RTX GPUs remains strong, and memory supply is constrained. In order to maximize memory availability, we are releasing the GeForce RTX 5070 Laptop GPU 12GB configuration with 24Gb G7 memory. This gives our partners access to an additional pool of memory to complement the 16Gb G7 supply that currently ships with most GeForce GPUs. The 12GB configuration will exist alongside the current 8GB configuration, and allows our partners to bring a broader range of GeForce RTX 5070 laptops to consumers.

The change is focused on VRAM capacity, not the GPU itself. The RTX 5070 Laptop GPU still uses the same Blackwell GPU configuration with 4608 CUDA cores. NVIDIA’s current laptop GPU spec table lists the RTX 5070 Laptop GPU with 8GB GDDR7 and 384 GB/s of bandwidth, while the RTX 5070 Ti Laptop GPU uses 12GB GDDR7 with 672 GB/s.
The new RTX 5070 Laptop GPU variant reportedly keeps the same 128-bit memory bus. The upgrade to 12GB is enabled by 24Gb, or 3GB, GDDR7 memory modules. That increases memory capacity by 50% over the original 8GB version without moving the GPU to a wider 192-bit interface.
The 12GB configuration should reduce the gap between RTX 5070 and RTX 5070 Ti laptops in memory capacity, but not in bandwidth or GPU core count.
