GeForce 9500 GT 512MB GDDR3		50 Watts
Radeon R7 250X 2GB		95 Watts
	Difference: 45 Watts (90%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X 2GB should perform much faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)

Radeon R7 250X 2GB		72000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon R7 250X 2GB will be quite a bit (more or less 355%) more effective at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 31200 (355%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 250X 2GB is superior to the GeForce 9500 GT 512MB GDDR3, and very much so. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 11600 (264%)

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 data (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
