GeForce GTX 550 Ti vs GeForce GTX 560 Ti

Intro

The GeForce GTX 550 Ti has a clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 24 ROPs.

Compare that to the GeForce GTX 560 Ti, which uses a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 RAM runs at a frequency of 1002 MHz on this card. It features 384 SPUs along with 64 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
