The GeForce 7800 GTX 512 was a high-end graphics card by NVIDIA, launched in November 2005. Built on the 110 nm process, and based on the G70 graphics processor, in its GF-7800-U-A2 variant, the card supports DirectX 9.0c. The G70 graphics processor is a large chip with a die area of 333 mm² and 302 million transistors. It features 24 pixel shaders and 8 vertex shaders, 24 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 placed 512 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 550 MHz, memory is running at 850 MHz.
Being a dual-slot card, its power draw is rated at 108 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 7800 GTX 512 is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 228 mm in length, and features a dual-slot cooling solution. Its price at launch was 649 US Dollars.
