NVIDIA has officially announced the GeForce MX450 for budget gaming notebooks, succeeding the recently launched MX350. It will come with GDDR6 memory and PCIe 4.0 support. Ironically, this is NVIDIA’s first GPU to support the PCIe 4 standard, as well as the first MX series part to include the higher-end GDDR6 memory.
There aren’t many details regarding the specifications or the GPU die used to power the MX450, but it’ll likely be based on the TU117, same as the GTX 1650 family.

This was a much-needed upgrade as the MX350 is barely faster than AMD’s higher-end integrated 7nm Vega 7 and Vega 8 GPUs, making the discrete GPU a rather unnecessary addition. Furthermore, as Tiger Lake with its Gen 12 graphics is going to be even faster, the MX350 simply can’t be paired with the same. Therefore, the newer MX450 based on the Turing architecture, unlike the MX350 which leveraged Pascal.
We are likely going to see an increased core count as well, somewhere in the 400-500 range with 4GB of GDDR6 memory and a 128-bit bus. As Renoir doesn’t support PCIe 4, these GPUs will only be paired with the upcoming Tiger Lake laptops for the time being.
As expected, laptops featuring the MX450 will be launched starting October, with the Lenovo Yoga Slim 7 and other premium ultrabooks leading the pack.
