Radeon HD 6850 vs Radeon HD 6950 2GB
Intro
The Radeon HD 6850 uses a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular card. It features 960 SPUs as well as 48 TAUs and 32 ROPs.Compare all that to the Radeon HD 6950 2GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular card. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

One Response to “Radeon HD 6850 vs Radeon HD 6950 2GB”[...] Radeon HD 6850 vs Radeon HD 6950 2GB – Performance Comparison Benchmarks @ Hardware Compare afgaande van de tests zou ik voor de 6950 gaan. Maar je al je hardware in rekening nemen en weten of je voeding goed genoeg is er voor. dat zou op zich geen al te groot probleem zijn. verder als de prijs inderdaad maar 30 euro verschilt tussen de kaarten en het nog steeds in de je budget past de 6950 nemen. __________________ Nu: SQ 1x220kg - BP 1x150kg - DL 1x215kg - MP 1x100kg Doel eind 2011: SQ 1x280kg - BP 1x180kg - DL 1x280kg - MP 1x130kg [...]
