Radeon R9 290X vs Radeon RX 590

Intro

The Radeon R9 290X features a GPU clock speed of 800 MHz, and the 4096 MB of GDDR5 RAM runs at 1250 MHz through a 512-bit bus. It also is made up of 2816 Stream Processors, 176 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 590, which makes use of a 12 nm design. AMD has set the core frequency at 1469 MHz. The GDDR5 RAM runs at a frequency of 2000 MHz on this model. It features 2304 SPUs as well as 144 TAUs and 32 Rasterization Operator Units.

Radeon RX 590 262144 MB/sec
Difference: 57856 (22%)

Texel Rate

The Radeon RX 590 will be much (more or less 50%) more effective at anisotropic filtering than the Radeon R9 290X. (explain)

Radeon RX 590 211536 Mtexels/sec
Radeon R9 290X 140800 Mtexels/sec
Difference: 70736 (50%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 290X is a better choice, but it probably won't make a huge difference. (explain)

Radeon R9 290X 51200 Mpixels/sec
Radeon RX 590 47008 Mpixels/sec
Difference: 4192 (9%)

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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
