GeForce 9800 GTX vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which features core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9800 GTX should in theory be a little bit faster than the Radeon R7 M260X overall. (explain)

GeForce 9800 GTX		70400 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 6400 (10%)

Texel Rate

The GeForce 9800 GTX will be much (about 118%) more effective at texture filtering than the Radeon R7 M260X. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 23400 (118%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9800 GTX is superior to the Radeon R7 M260X, and very much so. (explain)

GeForce 9800 GTX		10800 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 4200 (64%)

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 megabytes per second) that can be moved past the external memory interface in a second. It's calculated 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 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of 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 amount 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
