GeForce 8800 GS vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which has clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260X should theoretically be a lot superior to the GeForce 8800 GS in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce 8800 GS will be quite a bit (about 33%) better at AF than the Radeon R7 M260X. (explain)

GeForce 8800 GS		26400 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 6600 (33%)

Pixel Rate

Both cards have the exact same pixel rate, so theoretically they should perform equally good at at anti-aliasing, and be able to handle the same screen resolutions. (explain)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
