GeForce 8800 GTS (G92) vs Radeon R7 250X 2GB

Intro

Compare all of that to the Radeon R7 250X 2GB, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X 2GB		95 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 40 Watts (42%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X 2GB should perform just a bit faster than the GeForce 8800 GTS (G92) overall. (explain)

Radeon R7 250X 2GB		72000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 9920 (16%)

Texel Rate

The GeForce 8800 GTS (G92) is just a bit (more or less 4%) better at texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 1600 (4%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is the winner, and very much so. (explain)

Radeon R7 250X 2GB		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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
