GeForce GTX 260 vs GeForce GTX 870M

Intro

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

Compare all that to the GeForce GTX 870M, which uses a 28 nm design. nVidia has set the core speed at 941 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.

The GeForce GTX 870M is quite a bit (more or less 186%) faster with regards to anisotropic filtering than the GeForce GTX 260. (explain)

GeForce GTX 870M 105392 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 68528 (186%)

Pixel Rate

The GeForce GTX 870M is a lot (approximately 40%) more effective at FSAA than the GeForce GTX 260, and able to handle higher screen resolutions better. (explain)

GeForce GTX 870M 22584 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 6456 (40%)

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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
