Nvidia announces GeForce MX450 laptop video card with pci-e 4.0 and gddr6

Nvidia has announced its GeForce MX450 video card. Nvidia does not give details about which GPU is in it and how fast it is. The manufacturer does let us know that the MX450 has pci-e 4.0 support and can be combined with gddr5 or gddr6.

As usual with MX GPUs, Nvidia does not provide technical specifications of the MX450 on its website. The manufacturer also does not mention a ‘performance score’. That was the case with the MX350; Nvidia gave that GPU a score that should reflect the performance in relation to an Intel IGPU.

New is the support for gddr6 memory and the pci-e 4.0 interface. The latter will be possible in laptops with Intel’s Tiger Lake processors. AMD’s Ryzen 4000 laptop processors do not support pci-e 4.0, nor do current Intel laptop processors.

According to previous indications and rumors, the MX450 would be based on a variant of the TU117 GPU that is also in the GeForce GTX 1650. If so, it is probably a lower clocked variant or a version with fewer cores. The tdp of the MX450 would be 25W; the GTX 1650 has a tdp of 35W in the economical Max-Q version.

The MX450 is the successor to the MX350. That video card uses a variant of the GP107 GPU of the Pascal generation, which is also in the GeForce GTX 1050. GeForce MX GPUs are used in relatively inexpensive laptops, or as an additional video card in thin and light laptops. The MX cards are slower than the GTX and RTX variants. Nvidia says that laptops with the MX450 video card will be released from October.
