GeForce 9800 GX2 vs Radeon R7 260X

Intro

The GeForce 9800 GX2 makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory runs at a frequency of 1000 MHz on this particular model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R7 260X, which has clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 260X 115 Watts
GeForce 9800 GX2 197 Watts
Difference: 82 Watts (71%)

Memory Bandwidth

The GeForce 9800 GX2, in theory, should perform much faster than the Radeon R7 260X overall. (explain)

GeForce 9800 GX2 128000 MB/sec
Radeon R7 260X 104000 MB/sec
Difference: 24000 (23%)

Texel Rate

The GeForce 9800 GX2 is a lot (about 25%) faster with regards to AF than the Radeon R7 260X. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
Radeon R7 260X 61600 Mtexels/sec
Difference: 15200 (25%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9800 GX2 is the winner, but not by far. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
