GeForce GTX 275 vs GeForce GTX 550 Ti

Intro

The GeForce GTX 275 makes use of a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 RAM is set to run at a speed of 1134 MHz on this model. It features 240 SPUs along with 80 Texture Address Units and 28 Rasterization Operator Units.

Compare all of that to the GeForce GTX 550 Ti, which comes with GPU core speed of 900 MHz, and 1024 MB of GDDR5 RAM set to run at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 TAUs, and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
