Radeon HD 6950 2GB vs Radeon HD 6970
Intro
The Radeon HD 6950 2GB has a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is made up of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.Compare those specs to the Radeon HD 6970, which features GPU core speed of 880 MHz, and 2048 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 96 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to 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.
