Theoretically speaking, the Radeon R7 260X should be 48% faster than the GeForce 9800 GTX+ in general, because of its higher data rate. (explain)

Radeon R7 260X		104000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 33600 (48%)

Texel Rate

The Radeon R7 260X should be much (more or less 30%) faster with regards to texture filtering than the GeForce 9800 GTX+. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce 9800 GTX+		47232 Mtexels/sec
	Difference: 14368 (30%)

Pixel Rate

The Radeon R7 260X will be much (about 49%) better at FSAA than the GeForce 9800 GTX+, and also should be able to handle higher resolutions better. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 5792 (49%)

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 interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
