GeForce 8600 GT 512MB DDR2 vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which makes use of a 14 nm design. AMD has set the core frequency at 1168 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator 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 in general, 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 (more or less 1630%) more effective at anisotropic filtering 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

The Radeon RX 570 will be a lot (about 765%) more effective at FSAA than the GeForce 8600 GT 512MB DDR2, and capable of handling higher screen resolutions without slowing down too much. (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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
