Radeon RX 570 vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which comes with core speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 570		150 Watts
Radeon RX 590		175 Watts
	Difference: 25 Watts (17%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 590 should be 14% faster than the Radeon RX 570 in general, because of its higher data rate. (explain)

Radeon RX 590		262144 MB/sec
Radeon RX 570		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 590 should be a lot (more or less 41%) better at texture filtering than the Radeon RX 570. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 62032 (41%)

Pixel Rate

The Radeon RX 590 will be much (approximately 26%) more effective at full screen anti-aliasing than the Radeon RX 570, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 590		47008 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 9632 (26%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be applied in one second. This figure is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many 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.
