GeForce 8800 GTX vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which uses a 28 nm design. nVidia has set the core frequency at 1024 MHz. The GDDR5 RAM runs at a frequency of 1652 MHz on this model. It features 768 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

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

Memory Bandwidth

The GeForce GTX 950 should in theory be much faster than the GeForce 8800 GTX in general. (explain)

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

Texel Rate

The GeForce GTX 950 will be a lot (about 34%) more effective at AF than the GeForce 8800 GTX. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 950 is a better choice, by far. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
