Compare any two graphics cards:
Radeon HD 6850 vs Radeon HD 6950 2GB
IntroThe Radeon HD 6850 has core clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 960 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.Compare all of 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 runs at a speed of 1250 MHz on this specific model. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6950 2GB should theoretically be quite a bit better than the Radeon HD 6850 overall. (explain)
Texel RateThe Radeon HD 6950 2GB should be a lot (approximately 89%) better at AF than the Radeon HD 6850. (explain)
Pixel RateThe Radeon HD 6950 2GB should be a small bit (about 3%) faster with regards to FSAA than the Radeon HD 6850, and also should be able to handle higher resolutions without slowing down too much. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 many 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 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 [...]
