Radeon HD 4890 1GB vs Radeon RX 560

Intro

The Radeon HD 4890 1GB uses a 55 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM works at a frequency of 975 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Compare those specifications to the Radeon RX 560, which uses a 14 nm design. AMD has set the core frequency at 1175 MHz. The GDDR5 memory works at a frequency of 7000 MHz on this specific model. It features 1024 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560 80 Watts
Radeon HD 4890 1GB 190 Watts
Difference: 110 Watts (138%)

Memory Bandwidth

In theory, the Radeon HD 4890 1GB will be 9% faster than the Radeon RX 560 in general, because of its higher bandwidth. (explain)

Radeon HD 4890 1GB 124800 MB/sec
Radeon RX 560 114688 MB/sec
Difference: 10112 (9%)

Texel Rate

The Radeon RX 560 is quite a bit (approximately 88%) better at anisotropic filtering than the Radeon HD 4890 1GB. (explain)

Radeon RX 560 75200 Mtexels/sec
Radeon HD 4890 1GB 40000 Mtexels/sec
Difference: 35200 (88%)

Pixel Rate

The Radeon RX 560 is a bit (approximately 18%) more effective at AA than the Radeon HD 4890 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 560 18800 Mpixels/sec
Radeon HD 4890 1GB 16000 Mpixels/sec
Difference: 2800 (18%)

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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 are processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
