GeForce GTX 275 vs GeForce GTX 560 Ti

Intro

The GeForce GTX 275 features a core clock frequency of 633 MHz and a GDDR3 memory frequency of 1134 MHz. It also uses a 448-bit memory bus, and makes use of a 55 nm design. It is comprised of 240 SPUs, 80 Texture Address Units, and 28 ROPs.

Compare those specifications to the GeForce GTX 560 Ti, which has GPU core speed of 822 MHz, and 1024 MB of GDDR5 memory running at 1002 MHz through a 256-bit bus. It also features 384 Stream Processors, 64 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
