Compare any two graphics cards:
Radeon HD 7950 vs Radeon R9 280
IntroThe Radeon HD 7950 features a core clock frequency of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It features 1792 SPUs, 112 TAUs, and 32 ROPs.Compare that to the Radeon R9 280, which makes use of a 28 nm design. AMD has set the core frequency at 933 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this model. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe Radeon R9 280 should be a small bit (about 17%) more effective at texture filtering than the Radeon HD 7950. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 280 is superior to the Radeon HD 7950, but it probably won't make a huge difference. (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 MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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.

One Response to “Radeon HD 7950 vs Radeon R9 280”7950 does not have 1500 MB of RAM, it has 3G. Not at 800 MHz, it is at 850, auto-boosts to 925 if not hot. R9 has 850, boosts to 950 is not hot (1000 for the OC). It also has the same bus width, print density, mapping units and texture units becaue it's the same fucking card. It is not 17% better, not higher TDP.
This is basically all you do. Compare cards. You can't catch on the same card being the same? Way to provide a service. 10 buttons so I can share my findings with the world, not one to report an issue. The bloody frame with prices ALL say 7950 3GB. You didn't even read your own page.
