GeForce 8800 GTS (G92) vs Radeon R7 250

Intro

Compare those specs to the Radeon R7 250, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this particular model. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250		65 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 70 Watts (108%)

Memory Bandwidth

Theoretically, the Radeon R7 250 should perform just a bit faster than the GeForce 8800 GTS (G92) in general. (explain)

Radeon R7 250		73600 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 11520 (19%)

Texel Rate

The GeForce 8800 GTS (G92) should be much (approximately 73%) more effective at anisotropic filtering than the Radeon R7 250. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 17600 (73%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G92) is a better choice, and very much so. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 2400 (30%)

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 (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
