GeForce 8800 GT 512MB vs Radeon RX 570

Intro

Compare that to the Radeon RX 570, which comes with a core clock speed of 1168 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

GeForce 8800 GT 512MB		105 Watts
Radeon RX 570		150 Watts
	Difference: 45 Watts (43%)

Memory Bandwidth

In theory, the Radeon RX 570 should be 298% faster than the GeForce 8800 GT 512MB in general, because of its greater data rate. (explain)

Radeon RX 570		229376 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 171776 (298%)

Texel Rate

The Radeon RX 570 will be quite a bit (approximately 345%) better at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 115904 (345%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 570 is superior to the GeForce 8800 GT 512MB, by far. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 27776 (289%)

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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
