Radeon HD 6950 2GB vs Radeon HD 6970
Intro
The Radeon HD 6950 2GB makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular card. It features 1408 SPUs along with 88 TAUs and 32 ROPs.Compare those specs to the Radeon HD 6970, which features core clock speeds of 880 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs along with 96 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across 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 type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of 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 per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum 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.
