GeForce GTX 550 Ti vs GeForce GTX 580 3GB

Intro

The GeForce GTX 550 Ti comes with a clock speed of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 24 ROPs.

Compare that to the GeForce GTX 580 3GB, which features a clock speed of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 384-bit memory bus, and makes use of a 40 nm design. It is comprised of 512 SPUs, 64 Texture Address Units, and 48 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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