Schenker Key 18 Pro E25 review: High-end workstation with RTX 5090 and 256 GB RAM
Intel Core Ultra 9 275HX | Nvidia GeForce RTX 5090 Laptop | 18.00" | 4.1 kg
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.
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.
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.
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).
