Radeon R9 290X vs Radeon RX 590

Intro

The Radeon R9 290X makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this particular model. It features 2816 SPUs along with 176 Texture Address Units and 64 ROPs.

Compare those specifications to the Radeon RX 590, which features a clock frequency of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 256-bit memory bus, and uses a 12 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590 175 Watts
Radeon R9 290X 300 Watts
Difference: 125 Watts (71%)

Memory Bandwidth

Theoretically, the Radeon R9 290X should perform quite a bit faster than the Radeon RX 590 in general. (explain)

Radeon R9 290X 320000 MB/sec
Radeon RX 590 262144 MB/sec
Difference: 57856 (22%)

Texel Rate

The Radeon RX 590 is quite a bit (about 50%) more effective at texture 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 information (counted in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed 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 higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
