GeForce 8600 GT 512MB DDR2 vs Radeon R9 290

Intro

The GeForce 8600 GT 512MB DDR2 makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 RAM works at a frequency of 400 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the Radeon R9 290, which comes with a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 512-bit memory bus, and makes use of a 28 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved across 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. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
