Radeon HD 6950 2GB vs Radeon HD 6970
Intro
The Radeon HD 6950 2GB comes with a GPU clock speed of 800 MHz, and the 2048 MB of GDDR5 memory is set to run at 1250 MHz through a 256-bit bus. It also is made up of 1408 Stream Processors, 88 Texture Address Units, and 32 Raster Operation Units.Compare all of that to the Radeon HD 6970, which has core speeds of 880 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

5 Responses to “Radeon HD 6950 2GB vs Radeon HD 6970”Could you compare HD6950 2GB with HD6970 mod to the factory HD6970?
JD it would be the same.
If the 6950 was flashed bios to 6970 will it give the same fps and same performance ?

@swiftymicvey .. No it won't perform as good as a stock 6970, as its behind on the TMU's, core & memory clocks. Unless any of the folk talking up the 6950 can magically bump the TMU's and simultaneously bump the core & memory on a 6950 to the same level, it will still be behind overall in benchmarks and in real-time, 3D gaming performance. No amount of wishful thinking will change that.
