GeForce 9800 GX2 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which has a clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 9800 GX2 should in theory be much superior to the Radeon R7 M260X in general. (explain)

GeForce 9800 GX2		128000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 64000 (100%)

Texel Rate

The GeForce 9800 GX2 is a lot (about 288%) faster with regards to AF than the Radeon R7 M260X. (explain)

GeForce 9800 GX2		76800 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 57000 (288%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9800 GX2 is a better choice, by a large margin. (explain)

GeForce 9800 GX2		19200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 12600 (191%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
