Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X is 181% faster than the GeForce 9500 GT 512MB GDDR3 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R7 250X should be quite a bit (about 355%) faster with regards to anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

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

Pixel Rate

The Radeon R7 250X will be quite a bit (more or less 264%) faster with regards to anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 250X		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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
