Nvidia has announced the newest GPU in its 600 series of video-processing hardware: the GeForce GTX 660 Ti. It's designed primarily for gamers and enthusiasts, and occupies the new lowest stratum of the company's currently available desktop video offerings.
Like other current-generation video cards, the GTX 660 Ti will support DirectX 11 rendering, which lets games take advantage of visual features such as tessellation. As is true with all of Nvidia's cards, it will also utilise PhysX onboard physics processing. Kepler-specific features, such as temporal anti-aliasing (TXAA), a combination of hardware-based Morphological Anti-Aliasing (or MSAA) and Fast Approximate Anti-Aliasing (FXAA), and GPU Boost, which dynamically increases the card's clock speed if the thermal and electrical headroom exist, are supported as well.
Video cards based on the standard GTX 660 Ti specification will be loaded with 1,344 CUDA parallel processing cores, 112 texture units, and 24 ROP units, organised in seven "next-generation Streaming Multiprocessor" (or SMX units), and have a base clock speed of 915MHz, which can boost to as much as 980MHz. The cards will have 2GB of GDDR5 memory operating over a 192-bit interface, and at a data rate of 6GB/s; the total memory bandwidth is 144.2GB/s. GTX 660 Ti cards will require two six-pin PCI Express (PCIe) connectors from a power supply of at least 400 watts, and will have a TDP of 150 watts. Output connectors will be two dual-link DVI, one HDMI, and one DisplayPort 1.2.
Representatives from Nvidia said that they expect their board partners to release their own versions of GTX 660 Ti with very high overclocks. This could result in a slightly different set of outputs and higher power requirements, depending on the specific model.
GeForce GTX 660 Ti cards should be on sale effective today, with versions available from companies such as Asus, Colorful, EVGA, Galaxy, Gigabyte, MSI, and Zotac. Nvidia estimates that standard-clocked cards will cost approximately $299 (£190), with overclocked versions costing slightly more.
