TurboCache

Nvidia's TurboCache technology is a method of allowing video cards more available framebuffer memory by using both onboard video memory and main system memory. Main memory is accessed using the high-bandwidth PCI-Express bus.

TurboCache was developed as a means to provide a better cost/performance ratio by reducing the amount of memory modules on the video card. According to Nvidia, a GeForce 6200 with TurboCache will perform about four times better than the Intel GMA 900. As with integrated graphics, the operating system may report a lower amount of main memory than is physically present when main memory is used.

When TurboCache was introduced on the GeForce 6200 with TurboCache, there was confusion over how much local memory a buyer could expect from the TurboCache enabled video card. This figure could lie between 16-128 MiB, with Nvidia listing only total memory from both video memory and main memory. Eventually, NVIDIA included only video memory sizes on marketing and packaging.

While TC can improve 3D quality in games using a great deal of video memory for texture rendering, performance of games utilizing a large percent of system RAM (such as EA Games' Battlefield series and their mods that typically consume 512 MB-1 GB RAM) can suffer dramatically on systems with 1 GB RAM or below. Some users of such setups have attempted to disable TC.[ citation needed ] Such an option is not supported by NVIDIA's official drivers but can be accomplished using a registry modification for Windows XP users or a configuration file modification for X.Org Server users.

A video card with TurboCache typically is slower in 3D benchmarks than a similar video card which has its own discrete video memory.

Accelerated Graphics Port (AGP) is a parallel expansion card standard, designed for attaching a video card to a computer system to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards. Since 2004, AGP was progressively phased out in favor of PCI Express (PCIe), which is serial, as opposed to parallel; by mid-2008, PCI Express cards dominated the market and only a few AGP models were available, with GPU manufacturers and add-in board partners eventually dropping support for the interface in favor of PCI Express.

A graphics card is a computer expansion card that generates a feed of graphics output to a display device such as a monitor. Graphics cards are sometimes called discrete or dedicated graphics cards to emphasize their distinction to integrated graphics processor on the motherboard or the CPU. A graphics processing unit (GPU) that performs the necessary computations is the main component in a graphics card, but the acronym "GPU" is sometimes also used to erroneously refer to the graphics card as a whole.

GeForce is a brand of graphics processing units (GPUs) designed by Nvidia and marketed for the performance market. As of the GeForce 40 series, there have been eighteen iterations of the design. The first GeForce products were discrete GPUs designed for add-on graphics boards, intended for the high-margin PC gaming market, and later diversification of the product line covered all tiers of the PC graphics market, ranging from cost-sensitive GPUs integrated on motherboards, to mainstream add-in retail boards. Most recently, GeForce technology has been introduced into Nvidia's line of embedded application processors, designed for electronic handhelds and mobile handsets.
