Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.

Radeon is much..much better..dx

Bruder95 says:

rasta dumm? oder so mann siehts eindeutig das die 560 besser ist TAUSEND MAL BESSER bei alles

maiky says:

Bruder95 auch dumm? Dafür das die Radeon nur die hälfte kostet, ist sie Leistungstechnisch fast genau so gut. die paar texel und pixel machen minimal etwas aus. bei Spielen wie BF3 wird man den Unterschied etwas merken.

HOW THE f**K U CAME UP WITH THE IDEA THAT RANDON 6850 IS BETTER THEN 560GTX CAN4T U SEE THE BOARD

6850 core speed is infact higher than 775 usually depending on the brand is 790-820

On even modest o'clocks with the HD 6850, +11% core & +12.5% memory (860/1125), the 6850 posts: pixel fill @ 27.5GP/s, texture fill @ 41.3GT/s and mem' b/w @ 144GB/s. Bear in mind, i've brought the clocks down from the core:950/mem:1175, that i've been using for 3D gaming, just to demonstrate the incrdible o'clock potential the 6850 has. Obviously, YEMV. So it's a no-brainer .. if you want a very good card - out of the box, the GTX 560 is it. If you want an excellent o'clock candidate that has huge potential beyond its stock/factory settings? Than you probably wanna go with the HD 6850.

@SAM ... i think you and rilder should "hook up" ... you seem to think *alot* alike.
