GeForce 9800 GX2 vs Radeon RX 560

Intro

The GeForce 9800 GX2 features core speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon RX 560, which comes with a core clock speed of 1175 MHz and a GDDR5 memory frequency of 7000 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is comprised of 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 will be 12% faster than the Radeon RX 560 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GX2 will be a bit (approximately 2%) better at AF 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 a high screen resolution is important to you, then the GeForce 9800 GX2 is superior to the Radeon RX 560, but it probably won't make a huge difference. (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 data (measured in MB per second) that can be transported 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 memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, 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 card could possibly record to the local memory in a 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
