GeForce 9500 GT 512MB GDDR3 vs Radeon RX 590

Intro

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 590 is superior to the GeForce 9500 GT 512MB GDDR3, by a large margin. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 42608 (968%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 are applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher 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 maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
