NVIDIA GeForce RTX 5070 Ti Laptop vs NVIDIA GeForce RTX 4080 Laptop GPU

NVIDIA GeForce RTX 5070 Ti Laptop

The Nvidia GeForce RTX 5070 Ti Laptop is a mobile graphics card from the Blackwell family for laptops, unveiled at CES 2025. It is based on the GB205 chip, featuring 5,888 shader/CUDA cores clocked at 847-1995 MHz (depending on the model) and 12 GB of GDDR7 memory with a 192-bit interface. The model also has 46 RT-cores, as well as 80 ROPs.

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, the RTX 5070 Ti laptop is 23% faster than the standard RTX 5070 laptop on average in benchmarks. Gaming performance delta is lower; here, the RTX 5070 Ti laptop is only 15% faster on average than the RTX 5070 laptop. The desktop counterpart, the RTX 5070 Ti, is 34% faster. Furthermore, with the mentioned Multi-Frame Generation (MFG) you can get impressive frame rates, but keep latency in mind.

Power consumption

The GB205 chip is manufactured at TSMC in the 4N (custom 4NP 5nm) process. The maximum allowed TGP for this model is 140 watts (including Dynamic Boost).

NVIDIA GeForce RTX 4080 Laptop GPU

The NVIDIA GeForce RTX 4080 Laptop GPU (Codename GN21-X9) is a high-end laptop GPU. It is based on the AD104 chip as the desktop RTX 4070 Ti and use the Ada Lovelace architecture. The AD104 chip offers a maximum of 7.680 shaders (e.g., the RTX 4070 Ti Desktop) from which RTX 4080 Laptop uses 7.424 and a 192 Bit memory bus. The RTX 4080 mobile uses 12 GB GDDR6 dedicated graphics memory with a clock speed of 16 or 20 Gbps (effective). The TGP (Total Graphics Power) can be configured between 60 and 150 Watt (+ 25 Watt Dynamic Boost from the CPU) leading to different performance levels (the desktop RTX 4070 Ti uses 285 Watt for comparisons). The boost clock speed ranges from 1350 MHz (at 60 Watt TGP) up to 2280 MHz (150W). Therefore, the performance is also depending a lot on the power setting used for the RTX 4080 mobile in the laptop.

The synthetic performance of the RTX 4080 is clearly above the mobile RTX 3080 Ti in our tests and only bested by the mobile RTX 4090. In actual games we saw that even demanding games with Raytracing enabled (like F1 23) could be played in QHD and maximum settings. Less demanding games like Baldur's Gate 3 can be fluently played in 4k (see results below).

The RTX 4080 offers 232 tensor cores (4th gen) that enable DLSS 3 including frame generation for supported games. Furthermore, 58 raytracing cores (4rd gen) can be used for raytracing effects in supported games.

The AD103 chip is manufactured in 5nm at TSMC (4N process).
