Radeon HD 6790 vs Radeon RX 560

Intro

The Radeon HD 6790 features core speeds of 840 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 memory. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon RX 560, which has a GPU core clock speed of 1175 MHz, and 4096 MB of GDDR5 memory running at 7000 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560 80 Watts
Radeon HD 6790 150 Watts
Difference: 70 Watts (88%)

Memory Bandwidth

Performance-wise, the Radeon HD 6790 should theoretically be a little bit superior to the Radeon RX 560 in general. (explain)

Radeon HD 6790 134400 MB/sec
Radeon RX 560 114688 MB/sec
Difference: 19712 (17%)

Texel Rate

The Radeon RX 560 should be quite a bit (approximately 124%) more effective at AF than the Radeon HD 6790. (explain)

Radeon RX 560 75200 Mtexels/sec
Radeon HD 6790 33600 Mtexels/sec
Difference: 41600 (124%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 560 is the winner, and very much so. (explain)

Radeon RX 560 18800 Mpixels/sec
Radeon HD 6790 13440 Mpixels/sec
Difference: 5360 (40%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
