GeForce 9800 GTX+ vs GeForce GTX 960M

Intro

Compare those specifications to the GeForce GTX 960M, which features a clock speed of 1096 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 80 Watts (123%)

Memory Bandwidth

In theory, the GeForce 9800 GTX+ should perform a little bit faster than the GeForce GTX 960M in general. (explain)

GeForce 9800 GTX+		70400 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 6400 (10%)

Texel Rate

The GeForce 9800 GTX+ should be just a bit (more or less 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

If using high levels of AA is important to you, then the GeForce GTX 960M is the winner, by far. (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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
