Radeon HD 5870 vs Radeon HD 6970
Intro
The Radeon HD 5870 has a GPU clock speed of 850 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1200 MHz through a 256-bit bus. It also features 1600(320x5) Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 6970, which has a core clock speed of 880 MHz and a GDDR5 memory speed of 1375 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is comprised of 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

One Response to “Radeon HD 5870 vs Radeon HD 6970”[...] presteert die kaart beter en kan die wel op mijn systeem en die vorige niet. Ter vergelijking: http://www.hwcompare.com/6353/radeon...adeon-hd-6970/ Dan zou je toch zeggen dat die hd 6970 ook teveel wordt? Of snap ik het verkeerd [...]
