Nvidia GeForce RTX 5070 Laptop vs Nvidia GeForce RTX 5090 Laptop

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.

Nvidia GeForce RTX 5090 Laptop

The Nvidia GeForce RTX 5090 Laptop is a mobile graphics card from the Blackwell family for laptops, which was presented at CES 2025 and was commercially available in April 2025.

Architecture

The GeForce RTX 5090 Mobile utilizes the GB203 chip and employs 10,496 shaders/CUDA cores, which is the maximum of 10,752 that the chip supports. This makes the RTX 5090 Laptop more similar to the RTX 5080 desktop variant (same chip) than the Desktop RTX 5090 with 20,760 cores and higher clock rates.

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

Performance

As our tests show, performance gains over a 175W RTX 4090 Laptop GPU are barely noticeable in 3DMark tests. Still, when it comes to overall gaming performance, the card is 2-19% faster than the previous mobile flagship. The fastest laptop variant we tested is only 5% behind the RTX 5080 desktop. This means that the 5090L is usually capable to display full details at 4k fluently (see below). Furthermore, with the mentioned Multi-Frame Generation (MFG) you can get impressive frame rates, but keep latency in mind.

Power consumption

The GB203 chip is manufactured at TSMC in the 4N (custom 4NP 5nm) process. The maximum TGP of the card can reach 175 watts (150 watts + 25 watts Dynamic Boost).
