Radeon HD 6850 vs Radeon HD 6950 2GB
Intro
The Radeon HD 6850 has a GPU core clock speed of 775 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 256-bit bus. It also features 960 Stream Processors, 48 Texture Address Units, and 32 Raster Operation Units.Compare those specs to the Radeon HD 6950 2GB, which has a clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach 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 [...]
