GeForce 8800 GT 1GB vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which comes with GPU core speed of 1469 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Radeon RX 590		211536 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 177936 (530%)

Pixel Rate

The Radeon RX 590 will be quite a bit (about 390%) better at full screen anti-aliasing than the GeForce 8800 GT 1GB, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 37408 (390%)

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 data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one 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 this number, the better the graphics 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 the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
