Radeon HD 5750 1GB		86 Watts
GeForce GTX 950		90 Watts
	Difference: 4 Watts (5%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950 will be 44% quicker than the Radeon HD 5750 1GB in general, due to its greater data rate. (explain)

GeForce GTX 950		105728 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 32128 (44%)

Texel Rate

The GeForce GTX 950 should be quite a bit (about 95%) better at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 23952 (95%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 950 is superior to the Radeon HD 5750 1GB, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 21568 (193%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 high 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 texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
