GeForce GTX 465 vs GeForce GTX 560

Intro

The GeForce GTX 465 features a GPU clock speed of 607 MHz, and the 1024 MB of GDDR5 RAM is set to run at 802 MHz through a 256-bit bus. It also features 352 Stream Processors, 44 Texture Address Units, and 32 ROPs.

Compare those specs to the GeForce GTX 560, which comes with a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher 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 most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
