According to a rumor originated from Chinese media Expreview, NVIDIA is preparing a brand-new variant of the GeForce GTX 1050 graphics card with 3GB of onboard memory. The additional memory could potentially increase the graphics card's performance in certain situations. However, Expreview speculates that NVIDIA might actually reduce the memory bus to 96 bits instead of maintaining the 128-bit bus. If this was to happen, actual performance on the GeForce GTX 1050 3GB might be even worse than the normal variant. Now, only time will tell if the rumors are true. If the 3GB variant does make it to the shelves, it would probably be exclusive to the Chinese market like the GeForce GTX 1060 with 5GB memory.
