GeForce GT 220 GDDR3 vs GeForce GTX 460 SE

Intro

The GeForce GT 220 GDDR3 has core clock speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 memory. It features 48 SPUs along with 16 TAUs and 8 ROPs.

Compare those specs to the GeForce GTX 460 SE, which has a clock speed of 650 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is comprised of 288 SPUs, 48 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
