NVIDIA GeForce RTX 4070 vs NVIDIA GeForce RTX 5070 Laptop

NVIDIA GeForce RTX 4070

The Nvidia GeForce RTX 4070 is a high-end desktop graphics card based on the AD104 chip using the Ada Lovelace architecture. The 4070 offers 5,888 cores and 12 GB GDDR6X graphics memory with a 192 bit memory bus and clocked at 21 Gbits. The card offers a good raytracing performance thanks to the 46 dedicated raytracing cores. For AI calculations (and DLSS 3 in games), the RTX 4070 has 184 Tensor cores.

The gaming performance is well suited for 2k/QHD gaming in most demanding games, and should be able to handle 4k gaming for lesser demanding games (or with reduced settings / DLSS activated). The raw gaming performance is comparable to an older RTX 3080 or a AMD Radeon 6800 XT. Compared to the similar named mobile GeForce RTX 4070 Laptop GPU, the desktop variant is much faster.

The AD104 chip is manufactured in the modern 5nm process at TSMC (4N with EUV) and specified with a TGP (Total Graphics Power) of 200 Watt (compared to the 450 Watt of the RTX 4090).

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.
