NVIDIA GeForce MX450

The Nvidia GeForce MX450 (N18S-G5, N18S-G5-B, N18S-LP codename) is a dedicated entry-level mobile graphics card designed for laptops. It utilizes the TU117 chip, the same as the GeForce GTX 1650, but with a reduced memory bus of 64 bits. Notably, the MX450 stands out as the first mobile GPU to feature PCIe Gen 4 x4 support.

There are currently four distinct versions available, each with varying specifications and performance characteristics:

Notably, the LP (Low Power) variant is notably slower compared to the typical 25 Watt variants. The 25 Watt GDDR6 N18S-G5 is expected to deliver up to 20% better performance than a GeForce GTX 1050, although it falls below the capabilities of a GTX 1650 (Max-Q). As a result, demanding games like Horizon Zero Dawn are best played at lower settings, while less demanding titles like F1 2020 can be enjoyed at medium to high settings in full HD.

Manufactured on a 12nm process at TSMC, the TU117 chip’s relatively low power consumption (TGP specified between 12 and 28.5 W) makes it suitable for thin and light laptops. Primarily, it is intended as an additional graphics card option for laptops based on Tiger Lake-U architecture.
