GeForce 9800 GX2 vs Radeon RX 460 2GB

Intro

The GeForce 9800 GX2 has a core clock frequency of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon RX 460 2GB, which features a clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

The GeForce 9800 GX2 will be quite a bit (about 26%) better at anisotropic filtering than the Radeon RX 460 2GB. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
Radeon RX 460 2GB 61040 Mtexels/sec
Difference: 15760 (26%)

Pixel Rate

The GeForce 9800 GX2 will be a small bit (about 10%) faster with regards to AA than the Radeon RX 460 2GB, and able to handle higher resolutions better. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
Radeon RX 460 2GB 17440 Mpixels/sec
Difference: 1760 (10%)

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 (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
