GeForce 9800 GX2 vs Radeon RX 560

Intro

The GeForce 9800 GX2 makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory works at a speed of 1000 MHz on this particular card. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare all that to the Radeon RX 560, which features GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 memory set to run at 7000 MHz through a 128-bit bus. It also features 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560 80 Watts
GeForce 9800 GX2 197 Watts
Difference: 117 Watts (146%)

Memory Bandwidth

In theory, the GeForce 9800 GX2 should be 12% faster than the Radeon RX 560 overall, because of its higher data rate. (explain)

GeForce 9800 GX2 128000 MB/sec
Radeon RX 560 114688 MB/sec
Difference: 13312 (12%)

Texel Rate

The GeForce 9800 GX2 should be a little bit (approximately 2%) better at texture filtering than the Radeon RX 560. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
Radeon RX 560 75200 Mtexels/sec
Difference: 1600 (2%)

Pixel Rate

If running with high levels of AA 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 560 18800 Mpixels/sec
Difference: 400 (2%)

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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
