GeForce 8800 GTX vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which has core clock speeds of 1024 MHz on the GPU, and 1652 MHz on the 2048 MB of GDDR5 memory. It features 768 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950		90 Watts
GeForce 8800 GTX		155 Watts
	Difference: 65 Watts (72%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950 should be 22% quicker than the GeForce 8800 GTX in general, because of its greater data rate. (explain)

GeForce GTX 950		105728 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 19328 (22%)

Texel Rate

The GeForce GTX 950 should be quite a bit (approximately 34%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 12352 (34%)

Pixel Rate

The GeForce GTX 950 should be much (more or less 137%) faster with regards to AA than the GeForce 8800 GTX, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 18968 (137%)

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
