Compare any two graphics cards:
Radeon HD 6990 vs Radeon HD 7970
IntroThe Radeon HD 6990 comes with a GPU core speed of 830 MHz, and the 2048 MB of GDDR5 memory runs at 1250 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 7970, which uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory runs at a frequency of 1375 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6990 should theoretically be much better than the Radeon HD 7970 in general. (explain)
Texel RateThe Radeon HD 6990 should be quite a bit (more or less 35%) faster with regards to anisotropic filtering than the Radeon HD 7970. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6990 is superior to the Radeon HD 7970, by far. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.

8 Responses to “Radeon HD 6990 vs Radeon HD 7970”LOL and i was just about to buy a 7970! imma going for a 6990
Is Superkewldude retarded?
Dont just look at performance look at the power consumtion too :l
OMG how about 6990 in crossfire!
😛
if you look at the specs, really effective bandwidth would be better on the 7970 because of the PCIe 3.0 (providing you have a PCIe 3.0 compatible board) and it has better open GL 4.2 admittedly its only .1 better but thats the difference between playing BRINK and not playing BRINK.or any other game. and note too that the 6990 here has 2 cores where as the 7970 has one.

i think, we should waiting for 7990 😀 more fantastic than above.
I think, we should know that the 7990 🙂 will be expensive as FUUUUUUUUUUUUUUUUUUUUUUUU
