Radeon R9 295X2 vs Radeon RX 590

Intro

The Radeon R9 295X2 comes with a core clock speed of 1018 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 512-bit memory bus, and uses a 28 nm design. It features 2816 SPUs, 176 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 590, which has core clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Texel Rate

The Radeon R9 295X2 should be quite a bit (approximately 69%) better at anisotropic filtering than the Radeon RX 590. (explain)

Radeon R9 295X2 358336 Mtexels/sec
Radeon RX 590 211536 Mtexels/sec
Difference: 146800 (69%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 295X2 is superior to the Radeon RX 590, and very much so. (explain)

Radeon R9 295X2 130304 Mpixels/sec
Radeon RX 590 47008 Mpixels/sec
Difference: 83296 (177%)

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 MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
