GeForce 9800 GTX+ vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which has clock speeds of 1096 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 960M		64000 MB/sec
	Difference: 6400 (10%)

Texel Rate

The GeForce 9800 GTX+ is just a bit (about 8%) better at texture filtering than the GeForce GTX 960M. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GTX 960M		43840 Mtexels/sec
	Difference: 3392 (8%)

Pixel Rate

The GeForce GTX 960M will be quite a bit (about 49%) more effective at full screen anti-aliasing than the GeForce 9800 GTX+, and also will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 5728 (49%)

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: Bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus 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 ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few 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.
