NVIDIA upgrades RTX 5070 laptops with 12GB VRAM option

NVIDIA is expanding its Blackwell laptop lineup with the GeForce RTX 5070 12GB Laptop GPU. Confirmed by a quiet driver update blog post, this GPU aims to address longstanding user feedback about the VRAM limitations of NVIDIA's mid-range mobile silicon.

Rather than a direct replacement, the 12GB model will serve as a higher-tier alternative to the existing 8GB model. In other words, laptops with the larger memory capacity model will carry a price premium.

This is not a new GPU core with a wider memory bus. At its core is the same GB206 chip, featuring 4,608 CUDA cores and a 128-bit interface made up of four 32-bit channels. For the 12GB version, NVIDIA is using higher-density GDDR7 modules, with each channel populated by a 3GB chip, for a total of 12GB. By comparison, the original 8GB version uses 2GB modules per channel, for a total of 8GB across the same bus.

While the computational capacity remains unchanged, a 50% increase in the memory capacity provides much-needed breathing room for 1440p gaming and local AI workloads. If you're an AI enthusiast, the extra VRAM should allow you to run quantized 9B-14B parameter models for local LLM use.

You might think this is an odd move given the constraints on memory supply. However, NVIDIA claims it is offering laptop manufacturers a "Plan B" to keep assembly lines moving when standard 2GB modules are scarce. Obviously, this isn't a free upgrade. Since NVIDIA does not dictate the final sticker price of laptops, these 12GB variants will naturally command a premium.

While prices vary by sales, RTX 5070 laptops typically fall in the $1,400 - $2,200 range, while the RTX 5070 Ti falls in the $1,800 - $2,500 range. There is some overlap, largely due to premium models that command much higher prices.

At launch, NVIDIA suggested a $1,299 floor for the 5070 and $1,599 for the Ti, though those numbers rarely reflect what you'll actually pay at a major retailer. As such, we can expect brand-new RTX 5070 12GB offerings somewhere in between the two, likely in the $1,600 to $1,900 zone, though higher-end models may command north of $2,000.

With the current price overlap, you might find yourself in a situation where a Ti-equipped laptop costs only 10% more than a premium 12GB 5070 model. In that scenario, the extra $150-$200 could land you 28% more CUDA cores and 50% more memory bandwidth via the Ti's wider 192-bit bus, both of which are crucial for maintaining high frame rates at 1440p.

The performance difference between the 8GB and 12GB 5070 models should be minimal, unless we're talking about memory-bound games. In any case, we can expect laptop manufacturers to showcase new configurations with the 12GB 5070 at Computex, or earlier.
