GeForce 9800 GX2 vs Radeon R7 M260X

Intro

The GeForce 9800 GX2 comes with a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 memory is set to run at 1000 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon R7 M260X, which features core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9800 GX2 should in theory perform much faster than the Radeon R7 M260X overall. (explain)

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

Texel Rate

The GeForce 9800 GX2 will be a lot (approximately 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 is quite a bit (about 191%) better at FSAA than the Radeon R7 M260X, and will be able to handle higher screen 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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 can be applied per second. This is worked out 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
