Radeon R7 250X 2GB vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which uses a 12 nm design. AMD has set the core frequency at 1469 MHz. The GDDR5 RAM runs at a speed of 2000 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X 2GB		95 Watts
Radeon RX 590		175 Watts
	Difference: 80 Watts (84%)

Memory Bandwidth

The Radeon RX 590, in theory, should be quite a bit faster than the Radeon R7 250X 2GB overall. (explain)

Radeon RX 590		262144 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 190144 (264%)

Texel Rate

The Radeon RX 590 should be much (approximately 429%) more effective at anisotropic filtering than the Radeon R7 250X 2GB. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 171536 (429%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 590 is a better choice, by far. (explain)

Radeon RX 590		47008 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 31008 (194%)

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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
