NVIDIA GeForce MX450 vs Intel UHD Graphics Xe 16EUs (Tiger Lake-H)

NVIDIA GeForce MX450

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

Currently four different versions are available with different specifications and performance:

N18S-G5-B: GBD-128 Package, 1395 - 1575 MHz, GDDR6 5001 MHz, 28.5 W
N18S-G5: GB2E-64 Package, 1395 - 1575 MHz, GDDR6 5001 MHz, 25 W
N18S-G5: GB2E-64 Package, 1395 - 1575 MHz, GDDR5 3501 MHz, 25 W
N18S-LP: GB2E-64 Package, 720 - 930 MHz, GDDR6 5001 MHz, 12 W

Especially the LP = Low Power variant is significantly slower than the typical 25 Watt variant.

The 25 Watt GDDR6 N18S-G5 should be up to 20% faster than a GeForce GTX 1050 but of course below a GTX 1650 (Max-Q). Therefore, demanding games like Horizon Zero Dawn should run lowest settings. Less demanding games like F1 2020 can be played in medium to high settings and full HD.

The TU117 chip is manufactured in 12nm at TSMC and thanks to the relatively low power consumption (TGP specified between 12 and 28.5 W) the dGPU is also suited for thin and light laptops. Mostly it is intended as an additional graphics card for Tiger Lake-U based laptops.
