GeForce 9800 GX2 vs Radeon R7 M260X

Intro

The GeForce 9800 GX2 has a GPU core 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 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GX2 will be 100% quicker than the Radeon R7 M260X overall, because of its greater data rate. (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 AF 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 should be quite a bit (more or less 191%) more effective at AA than the Radeon R7 M260X, and will be capable of handling higher resolutions while still performing well. (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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out 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 filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
