GeForce 9800 GX2 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9800 GX2 should theoretically be quite a bit faster than 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 should be much (more or less 288%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

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

Pixel Rate

The GeForce 9800 GX2 will be a lot (about 191%) faster with regards to FSAA than the Radeon R7 M260X, and should be capable of handling higher resolutions better. (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 (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount 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 amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
