NVIDIA GeForce RTX 5070 12GB: specifications and details of the new graphics card for laptops

NVIDIA has added a new configuration of the GeForce RTX 5070 video card with 12 GB of video memory to its line of mobile graphics without official announcements. Confirmation of the existence of the updated version was found in the official notes for the new GeForce driver version 596.36, which was first noticed by the experts of Tom’s Hardware publication.

A brief overview of the new product

The appearance of this version was a response to modern video memory (VRAM) requirements of games. The novelty will coexist on the market in parallel with the previously presented 8 GB model. It is important to note that NVIDIA does not replace one version with another, but gives vendors (such as ASUS, MSI or Lenovo) the opportunity to choose the configuration that best suits a specific laptop model and its price positioning.

Technical specifications

Despite the increase in memory, the main computing power of the card remained unchanged. The new RTX 5070 is based on the energy-efficient and powerful Blackwell architecture.

• CUDA cores: 4608
• Microarchitecture: Blackwell
• Base clock frequency: about 907 MHz
• Frequency in Boost mode: up to 1425 MHz
• Power consumption (TGP): approximately 50 W
• Memory type: GDDR7

The updated memory subsystem is based on modern GDDR7 modules with a capacity of 3 GB each. Thanks to the use of such modules, NVIDIA managed to increase the amount of video memory from 8 GB to 12 GB, while keeping the same 128-bit bus as in the basic version. As a result, the memory bandwidth remains stable at 384 GB/s.

Differences of RTX 5070 12 GB from other NVIDIA mobile graphics cards

In the current hierarchy of NVIDIA mobile accelerators, the new option occupies an intermediate position. It is more powerful than the standard RTX 5070 by 8 GB due to the amount of memory, but it is a step below the full version of the RTX 5070 Ti, which is also equipped with 12 GB of video memory, but has a large number of computing units.

Is it worth buying a laptop with an RTX 5070 12 GB?

Increasing VRAM to 12 GB is a critical upgrade in 2025. Modern AAA projects at high graphics settings with a resolution of 1440p often consume more than 8 GB of memory. An additional 4 GB will provide a more stable frame rate without jerks (stutters) associated with loading textures. In addition, 12 GB will be a serious help for work with video editing, rendering and neural networks in a portable format.
