GeForce 8800 GTX vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which comes with clock speeds of 1127 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960		120 Watts
GeForce 8800 GTX		155 Watts
	Difference: 35 Watts (29%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 960 should be much faster than the GeForce 8800 GTX overall. (explain)

GeForce GTX 960		112000 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 25600 (30%)

Texel Rate

The GeForce GTX 960 should be much (about 96%) more effective at anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 35328 (96%)

Pixel Rate

The GeForce GTX 960 is quite a bit (more or less 161%) more effective at FSAA than the GeForce 8800 GTX, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 22264 (161%)

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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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. The number is calculated by multiplying the amount of colour ROPs by the clock 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
