Radeon HD 4850 X2 512MB vs Radeon RX 560

Intro

The Radeon HD 4850 X2 512MB features a GPU clock speed of 625 MHz, and the 512 MB of GDDR3 RAM is set to run at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 RAM works at a speed of 7000 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560 80 Watts
Radeon HD 4850 X2 512MB 250 Watts
Difference: 170 Watts (213%)

Memory Bandwidth

Performance-wise, the Radeon HD 4850 X2 512MB should in theory be a little bit superior to the Radeon RX 560 in general. (explain)

Radeon HD 4850 X2 512MB 127104 MB/sec
Radeon RX 560 114688 MB/sec
Difference: 12416 (11%)

Texel Rate

The Radeon RX 560 is a lot (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

The Radeon HD 4850 X2 512MB is a bit (approximately 6%) better at AA than the Radeon RX 560, and should be capable of handling higher resolutions without losing too much performance. (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 largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen 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 number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
