NVIDIA GeForce RTX 5080 Laptop vs NVIDIA GeForce RTX 5070 Laptop

NVIDIA GeForce RTX 5080 Laptop

The Nvidia GeForce RTX 5080 Laptop is a high-end notebook graphics card that was presented at CES 2025 and went on sale in April 2025. 

Architecture

The GeForce RTX 5080 Mobile utilizes the Blackwell GB203 chip and employs 8,192 of the chip's 10,752 cores. Compared to the similar named desktop chips, it therefore is nearer to the desktop RTX 5070 (6.144 cores) than the similar named desktop RTX 5080 (10.752 cores). The memory bus is however like the desktop RTX 5080 a 256 Bit bus for 16 GB GDDR7.

As a novelty, Blackwell offers support for Multi-Frame Generation (MFG) with DLSS4, thanks to the 5th generation of Tensor cores.

Performance

The average theoretical performance of the laptop RTX 5080 is similar to the desktop RTX 5070 and the older RTX 4090 Laptop GPU (Time Spy GPU). In games (e.g. Doom: The dark ages), the performance is also on par with the old RTX 4090 Laptop GPU, although the RTX 5080 supports the already mentioned MFG option for impressive frame rates. Still the latency is the same, so you should start from at least 60 fps without frame generation.

Power consumption

The GB203 is manufactured at TSMC using the 4N FinFET process (custom 4NP 5nm). The maximum TGP of the card can reach 150 watts (125 watts + 25 watts Dynamic Boost). 

NVIDIA GeForce RTX 5070 Laptop

The Nvidia GeForce RTX 5070 Laptop is a mobile graphics card from the Blackwell family for laptops, which was unveiled at CES 2025. It is based on the GB206 chip with 4,608 shader / CUDA cores clocked at 1425 - 2347 MHz (depending on the model). The graphics memory used is 8 GB GDDR7 with a 128-bit memory bus.

Architecture

The Nvidia GeForce RTX 5070 laptop has new Tensor (5th generation) and RT cores (4th generation) with a performance of 798 AI TOPS. The Blackwell architecture is the first with the new DLSS 4 Multi Frame Generation, which can generate more frames per second thanks to improved AI capabilities, while using less memory and delivering better image quality. Nvidia has also managed to improve the performance and output quality of the DLSS, Frame Generation and Ray Reconstruction features (which were also available on the previous RTX 4000 series). In addition, the new models now support Reflex 2 mode with low latency and Frame Warp.

Performance

The gaming performance of the RTX 5070 Mobile is heavily dependent on the cooling and TDP settings of the laptop. As a result, the maximum clock rate can also vary from 1425 to 2347 MHz. On average, the performance is usually slightly above the old RTX 4070 Laptop GPU but below the RTX 3080 Ti laptop. A new feature of the Blackwell architecture is the support for multi-frame generation (MFG) in DLSS4. This allows significantly higher frame rates to be achieved, but without MFG you should already reach over 50 fps to achieve a playable latency.

The chip is manufactured in the current TSMC 4N process.
