GeForce GTX 260 vs GeForce GTX 970M

Intro

The GeForce GTX 260 features a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also is made up of 192 SPUs, 64 Texture Address Units, and 28 ROPs.

Compare those specifications to the GeForce GTX 970M, which has core clock speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1280 SPUs along with 80 Texture Address Units and 48 ROPs.

GeForce GTX 970M 73920 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 37056 (101%)

Pixel Rate

The GeForce GTX 970M is much (approximately 175%) more effective at AA than the GeForce GTX 260, and also capable of handling higher resolutions more effectively. (explain)

GeForce GTX 970M 44352 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 28224 (175%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
