Nvidia quietly launches 12GB RTX 5070 laptop GPU — midrange mobile gaming gets more VRAM amid the RAMpocalypse
Nvidia has quietly launched a 12GB version of the RTX 5070 laptop GPU, offering 50% more VRAM than the existing 8GB model without changes to memory bandwidth or core specifications. The new GPU uses 3GB memory modules and maintains a 128-bit bus width, aligning with the current 8GB variant's architecture. This release comes amid a global memory shortage, making the increased VRAM availability notable for midrange mobile gaming and creative workloads.
- ▪The RTX 5070 12GB mobile GPU has 50% more VRAM than the 8GB version but no official bandwidth improvements.
- ▪It uses a 128-bit memory interface with GDDR7 memory, maintaining 384 GB/s of bandwidth.
- ▪The 12GB model slots between the 8GB RTX 5070 and the 12GB RTX 5070 Ti in Nvidia's mobile lineup.
- ▪This launch occurs during an AI-driven memory shortage, a time when some manufacturers are reducing GPU memory capacities.
- ▪The higher VRAM capacity improves performance in AAA gaming and high-setting graphics workloads by reducing memory bottlenecks.
