GeForce GTX 260 Core 216 vs GeForce GTX 650

Intro

The GeForce GTX 260 Core 216 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM works at a frequency of 999 MHz on this model. It features 216 SPUs as well as 72 TAUs and 28 Rasterization Operator Units.

Compare that to the GeForce GTX 650, which makes use of a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this model. It features 384 SPUs as well as 32 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
