Nvidia GeForce RTX 5080 Laptop vs Nvidia GeForce RTX 5070 Laptop vs Nvidia GeForce RTX 5050 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, featuring 4,608 shader/CUDA cores clocked at 908-2520 MHz (depending on the model). The graphics memory used is 8 GB GDDR7 with a 128-bit memory bus. The RTX 5070 features 36 RT-cores and 48 ROPs. 

Performance

Our tests show that the RTX 5070 Laptop is negligibly faster than the previous RTX 4070 Laptop (1-3%) in games and up to ~5% faster in benchmarks. However, MFG (2x, 3x, and 4x) and DLSS support can help the 5070 to ensure higher and smoother frame rates. The desktop counterpart is 15-20% faster, depending on the resolution (without accounting for DLSS and MFG).

Power consumption

The GB206 chip is manufactured in the current TSMC 4N process. The total graphics power of this model ranges from 50 to 100 watts.

Nvidia GeForce RTX 5050 Laptop

The Nvidia GeForce RTX 5050 Laptop is a dedicated graphics card from the Blackwell family for laptops, which was presented by Team Green in June 2025. It uses the GB207 chip.

Like the RTX 4050 Laptop GPU, the GPU offers 2,560 unified shaders (CUDA cores) combined with a 128-bit memory bus for 8 GB GDDR7 graphics memory.

Other features of the GPU include native 5th generation ray tracing cores, PCIe 5 support, DisplayPort 2.1a and 440 TOPS AI performance (thanks to the built-in Tensor cores).

The performance without DLSS frame generation should be similar to the old RTX 4060 Laptop GPU laptop GPU. The RTX 5060 is 21 - 22% faster at 115 W (incl. Dynamic Boost) in 3DMark tests (via Videocardz). As usual, performance is heavily dependent on power consumption (TGP) and cooling. Therefore, there will also be significantly slower models in laptops.

The chip is produced at TSMC using the 4nm process (4N). The power consumption (TGP) is specified at 35-100 watts (115 watts incl. Dynamic Boost 2.0).
