GeForce 8600 GT 512MB DDR2 vs Radeon RX 570

Intro

The GeForce 8600 GT 512MB DDR2 has a GPU clock speed of 540 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

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

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

Texel Rate

The Radeon RX 570 should be much (more or less 1630%) more effective 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

The Radeon RX 570 should be quite a bit (approximately 765%) faster with regards to anti-aliasing than the GeForce 8600 GT 512MB DDR2, and also will be able to handle higher screen resolutions without losing too much performance. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
