Compare any two graphics cards:
Radeon HD 7950 vs Radeon HD 7970
IntroThe Radeon HD 7950 comes with a clock frequency of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It features 1792 SPUs, 112 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 7970, which features a core clock frequency of 925 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7970 should in theory be a small bit better than the Radeon HD 7950 in general. (explain)
Texel RateThe Radeon HD 7970 should be much (more or less 32%) better at texture filtering than the Radeon HD 7950. (explain)
Pixel RateThe Radeon HD 7970 will be a bit (approximately 16%) faster with regards to full screen anti-aliasing than the Radeon HD 7950, and able to handle higher screen 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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.

6 Responses to “Radeon HD 7950 vs Radeon HD 7970”I thought that the HD 7950 had 3GB of memory...
it does..... silllyyyyy
There is a 3GB version of the 7950. It's a separate item on the lists displayed on this site.
Go to the top of the page, click the dropdown lists, select the 3GB version. Now that wasn't hard, was it?
Yeah, I didn't saw it the first time... sorry, my bad.
