GeForce 8600 GT 512MB DDR2 vs Radeon RX 570

Intro

Compare all of that to the Radeon RX 570, which comes with GPU core speed of 1168 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
Radeon RX 570		150 Watts
	Difference: 103 Watts (219%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 570 will be 1692% quicker than the GeForce 8600 GT 512MB DDR2 overall, because of its greater data rate. (explain)

Radeon RX 570		229376 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 216576 (1692%)

Texel Rate

The Radeon RX 570 will be quite a bit (about 1630%) better at AF than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 140864 (1630%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 570 is the winner, and very much so. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 33056 (765%)

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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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