GeForce 8800 GTX vs GeForce GTX 950

Intro

Compare that to the GeForce GTX 950, which uses a 28 nm design. nVidia has set the core speed at 1024 MHz. The GDDR5 memory runs at a frequency of 1652 MHz on this particular card. It features 768 SPUs along with 48 Texture Address Units 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

The GeForce GTX 950 should in theory perform a lot faster than the GeForce 8800 GTX overall. (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%) 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

The GeForce GTX 950 will be much (more or less 137%) more effective at full screen anti-aliasing than the GeForce 8800 GTX, and capable of handling higher 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units 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 per second.

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