GeForce 9800 GTX vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which has clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GTX should be 10% quicker than the Radeon R7 M260X in general, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GTX is much (about 118%) faster with regards to AF than the Radeon R7 M260X. (explain)

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

Pixel Rate

The GeForce 9800 GTX should be quite a bit (approximately 64%) more effective at full screen anti-aliasing than the Radeon R7 M260X, and should be able to handle higher resolutions while still performing well. (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 information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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.
