GeForce GTX 260 Core 216 vs GeForce GTX 970M

Intro

Compare those specifications to the GeForce GTX 970M, which uses a 28 nm design. nVidia has set the core speed at 924 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific model. It features 1280 SPUs along with 80 TAUs and 48 Rasterization Operator Units.

	Difference: 32448 (78%)

Pixel Rate

The GeForce GTX 970M should be much (more or less 175%) faster with regards to anti-aliasing than the GeForce GTX 260 Core 216, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce GTX 260 Core 216		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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
