GeForce 8800 GTS (G92) vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which has GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Theoretically speaking, the Radeon R7 250X should perform a little bit faster than the GeForce 8800 GTS (G92) overall. (explain)

Radeon R7 250X		72000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 9920 (16%)

Texel Rate

The GeForce 8800 GTS (G92) will be a bit (about 4%) better at texture filtering than the Radeon R7 250X. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 1600 (4%)

Pixel Rate

The Radeon R7 250X should be much (more or less 54%) better at anti-aliasing than the GeForce 8800 GTS (G92), and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 250X		16000 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 5600 (54%)

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 (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, 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 most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
