NVIDIA is working on a Turing-based successor to the upcoming MX350 dGPU, according to our sources familiar with the matter. The new MX GPU will be based on the TU117 GPU found in the GTX 1650 and will be the first Turing card to feature PCIe Gen4 support. The TU117 MX GPU is designed to take on the Xe DG1 iGPU in Intel Tiger Lake processors and is expected to come in two variants with different package sizes.
