GeForce 8500 GT vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which features GPU core speed of 1469 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

GeForce 8500 GT		12800 MB/sec
	Difference: 249344 (1948%)

Texel Rate

The Radeon RX 590 should be quite a bit (more or less 5776%) better at AF than the GeForce 8500 GT. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 207936 (5776%)

Pixel Rate

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

Radeon RX 590		47008 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 45208 (2512%)

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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the potential to reach the max fill rate.
