GeForce 8600 GT 512MB DDR2 vs Radeon RX 570

Intro

The GeForce 8600 GT 512MB DDR2 features a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.

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

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
