GeForce 9800 GX2 vs Radeon R7 260X

Intro

The GeForce 9800 GX2 has a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 memory runs at 1000 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon R7 260X, which has a core clock speed of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Pixel Rate

The GeForce 9800 GX2 will be just a bit (approximately 9%) better at anti-aliasing than the Radeon R7 260X, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
Radeon R7 260X 17600 Mpixels/sec
Difference: 1600 (9%)

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 max amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling 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 can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
