GeForce 8800 GTS (G92) vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which comes with core clock speeds of 750 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

The Radeon R9 M295X will be much (about 131%) more effective at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 54400 (131%)

Pixel Rate

The Radeon R9 M295X is much (approximately 131%) faster with regards to AA than the GeForce 8800 GTS (G92), and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 13600 (131%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
