GeForce 8800 GS vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X should in theory be quite a bit faster than 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 much (about 33%) more effective 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 fill rate, so in theory they should perform equally good at at FSAA, and be able to handle the same 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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
