The GeForce Go 7800 was a mobile graphics chip by NVIDIA, launched on March 3rd, 2006. Built on the 110 nm process, and based on the G70 graphics processor, the chip supports DirectX 9.0c. Since GeForce Go 7800 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The G70 graphics processor is a large chip with a die area of 333 mm² and 302 million transistors. It features 16 pixel shaders and 6 vertex shaders, 16 texture mapping units, and 16 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). NVIDIA has paired 256 MB GDDR3 memory with the GeForce Go 7800, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 400 MHz, memory is running at 550 MHz.
Its power draw is rated at 35 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. GeForce Go 7800 is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
