GeForce 9800 GX2 vs Radeon RX 460 2GB

Intro

The GeForce 9800 GX2 uses 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 card. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the Radeon RX 460 2GB, which comes with a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

Texel Rate

The GeForce 9800 GX2 is quite a bit (more or less 26%) more effective at texture 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 is just a bit (about 10%) faster with regards to anti-aliasing than the Radeon RX 460 2GB, and able to handle higher screen resolutions without slowing down too much. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
