GeForce 9800 GX2 vs Radeon RX 460

Intro

The GeForce 9800 GX2 comes with core clock speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Compare those specifications to the Radeon RX 460, which comes with a clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 14 nm design. It features 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
GeForce 9800 GX2 197 Watts
Difference: 122 Watts (163%)

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GX2 should be 14% quicker than the Radeon RX 460 in general, due to its higher data rate. (explain)

GeForce 9800 GX2 128000 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 16000 (14%)

Texel Rate

The GeForce 9800 GX2 will be quite a bit (more or less 26%) more effective at texture filtering than the Radeon RX 460. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce 9800 GX2 is a better choice, though only just barely. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
Radeon RX 460 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 information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one 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 this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write 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 the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
