Compare any two graphics cards:
Radeon HD 6970 vs Radeon HD 7970
IntroThe Radeon HD 6970 makes use of a 40 nm design. AMD has clocked the core speed at 880 MHz. The GDDR5 RAM is set to run at a speed of 1375 MHz on this specific model. It features 1536 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.Compare those specs to the Radeon HD 7970, which has GPU core speed of 925 MHz, and 3072 MB of GDDR5 memory set to run at 1375 MHz through a 384-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe Radeon HD 7970 should in theory be a lot faster than the Radeon HD 6970 in general. (explain)
Texel RateThe Radeon HD 7970 will be a lot (approximately 40%) faster with regards to AF than the Radeon HD 6970. (explain)
Pixel RateThe Radeon HD 7970 is a bit (approximately 5%) faster with regards to FSAA than the Radeon HD 6970, and also will be capable of handling higher screen resolutions while still performing well. (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
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though. Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This 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 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 maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

But they are so loud :S
cheaper than plus 2 or extreme
