Radeon HD 4850 X2 512MB vs Radeon RX 560

Intro

The Radeon HD 4850 X2 512MB uses a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 memory is set to run at a speed of 993 MHz on this particular card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon RX 560, which features a clock frequency of 1175 MHz and a GDDR5 memory speed of 7000 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It features 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Radeon RX 560 114688 MB/sec
Difference: 12416 (11%)

Texel Rate

The Radeon RX 560 is quite a bit (about 50%) better at texture filtering than the Radeon HD 4850 X2 512MB. (explain)

Radeon RX 560 75200 Mtexels/sec
Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Difference: 25200 (50%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 4850 X2 512MB is a better choice, though not by far. (explain)

Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 1200 (6%)

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 max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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