GeForce GTX 260 vs GeForce GTX 880M

Intro

The GeForce GTX 260 comes with core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 192 SPUs along with 64 Texture Address Units and 28 Rasterization Operator Units.

Compare that to the GeForce GTX 880M, which uses a 28 nm design. nVidia has set the core frequency at 954 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this model. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
