Radeon HD 6850 vs Radeon HD 6950 2GB
Intro
The Radeon HD 6850 features core clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 960 SPUs as well as 48 Texture Address Units and 32 ROPs.Compare all that to the Radeon HD 6950 2GB, which features GPU core speed of 800 MHz, and 2048 MB of GDDR5 memory set to run at 1250 MHz through a 256-bit bus. It also features 1408 Stream Processors, 88 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the 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 [...]
