Radeon HD 5870 vs Radeon HD 6970
Intro
The Radeon HD 5870 features core speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 RAM. It features 1600(320x5) SPUs along with 80 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 6970, which uses a 40 nm design. AMD has set the core speed at 880 MHz. The GDDR5 memory is set to run at a frequency of 1375 MHz on this model. It features 1536 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably 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 [...]
