Compare any two graphics cards:
Radeon HD 6970 vs Radeon HD 7970
IntroThe Radeon HD 6970 has a clock frequency of 880 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It features 1536 SPUs, 96 Texture Address Units, and 32 ROPs.Compare all that to the Radeon HD 7970, which uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe Radeon HD 7970, in theory, should be a lot faster than the Radeon HD 6970 overall. (explain)
Texel RateThe Radeon HD 7970 should be much (more or less 40%) better at AF than the Radeon HD 6970. (explain)
Pixel RateThe Radeon HD 7970 will be a bit (about 5%) more effective at FSAA than the Radeon HD 6970, and capable of handling higher resolutions better. (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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If 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 can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

4 Responses to “Radeon HD 6970 vs Radeon HD 7970”lol guys, get a 6970, its a lot cheaper
Do want! But still, then I have to invest in a new Mobo, and then it would be about double the price of a 6990
6990 > 7970
2x 6970 > 6990 > 7970
But they are so loud :S
get 7970 and replace the cooler with arctic cooler 7970
cheaper than plus 2 or extreme
