Estimated to be 45-65% faster than the RTX 4080 laptop GPU

According to rumors, this is NVIDIA's next-generation GeForce RTX 5080 laptop GPU 45% to 65% faster than the RTX 4080 laptop GPU according to new leaks.

In a new video from Moore's Law is Dead, sources told him that the GB203 GPU that will make its way into the GeForce RTX 5080 laptop GPU will feature 8000+ CUDA cores and 16GB of next-gen GDDR7 memory should. Don't worry, this isn't the fastest Blackwell mobile GPU… that would be the GeForce RTX 5090 laptop GPU, which should have (an insane) 24GB of GDDR7.

The alleged RTX 5080 laptop GPU leaked here is based on a heavily stripped-down GB203 GPU, but MLID reckons the RTX 5080 laptop GPU will be “much more powerful” than the RTX 4080 laptop GPU. We expect the next-gen RTX 5080 laptop GPU to be 45% to 65% faster than the RTX 4080 laptop GPU, which is a huge deal for 2025 gaming laptops.

By using 28Gbps GDDR7 memory modules on the rumored RTX 5080 laptop GPU, NVIDIA would achieve similar memory bandwidth (close to 1TB/sec) as the desktop RTX 4090. MLID predicts the RTX 5080 laptop GPU will perform 45-65% faster than the RTX 4080 laptop GPU, but also 10-25% faster than the RTX 4090 16GB laptop GPU and even around the desktop RTX 4070 Ti or even RTX 4080 performance level.

We should expect the RTX 4080 desktop GPU to reach the performance levels of the laptop-focused RTX 5080 laptop GPU with a TDP of at least around 175W. We can expect big reveals of the RTX 50 laptop GPUs at CES 2025 in early 2025.
