Radeon R7 260X		115 Watts
	Difference: 10 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 260X is 81% faster than the GeForce 9800 GT 1GB in general, because of its greater data rate. (explain)

Radeon R7 260X		104000 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 46400 (81%)

Texel Rate

The Radeon R7 260X should be much (about 83%) better at AF than the GeForce 9800 GT 1GB. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 28000 (83%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 260X is superior to the GeForce 9800 GT 1GB, by a large margin. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 8000 (83%)

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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount 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 clock speed of the chip. The higher 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 maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
