GeForce GTX 465 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 465 features a GPU core 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 is comprised of 352 Stream Processors, 44 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the GeForce GTX 660 Ti, which has a clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 192-bit memory bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are applied per second. This is calculated by multiplying the total amount of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
