GeForce GTX 260 vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which features GPU clock speed of 825 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Radeon R7 M260X		19800 Mtexels/sec
	Difference: 17064 (86%)

Pixel Rate

The GeForce GTX 260 is quite a bit (more or less 144%) faster with regards to FSAA than the Radeon R7 M260X, and able to handle higher resolutions more effectively. (explain)

GeForce GTX 260		16128 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 9528 (144%)

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 (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
