GeForce GT 220 GDDR3 vs GeForce GTX 460 1GB

Intro

The GeForce GT 220 GDDR3 has a clock frequency of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare all that to the GeForce GTX 460 1GB, which uses a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this card. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
