We found out not too long ago that NVIDIA was suing Samsung and Qualcomm, without going after any other companies, even if those companies used chips and parts from Samsung and Qualcomm, but now we might have found out why: Samsung is rumored to be working on its own GPU.
The news is coming from Fudzilla, and is just a rumor right now, but the company has been reportedly hiring people from the likes of AMD, NVIDIA and Intel. If Samsung were to be building its own GPU, it would be competing directly against Qualcomm and NVIDIA, with the latter having a very capable SoC with its Tegra K1 processor.
If Samsung did build its own GPU, it would save itself from having to license one from another company, as it would have nearly all of the components it needs for a flagship device built-in-house, from the screen, right down to the GPU.
