GeForce 8600 GT 1GB DDR2 vs Radeon RX 570

Intro

Compare that to the Radeon RX 570, which uses a 14 nm design. AMD has clocked the core frequency at 1168 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this specific model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB DDR2		47 Watts
Radeon RX 570		150 Watts
	Difference: 103 Watts (219%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 570 should be 1692% faster than the GeForce 8600 GT 1GB DDR2 in general, due to its higher bandwidth. (explain)

Radeon RX 570		229376 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 216576 (1692%)

Texel Rate

The Radeon RX 570 will be quite a bit (more or less 1630%) better at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce 8600 GT 1GB 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, by far. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce 8600 GT 1GB 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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
