Compare any two graphics cards:
Radeon HD 6950 2GB vs Radeon R9 295X2
IntroThe Radeon HD 6950 2GB makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this specific model. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.Compare all that to the Radeon R9 295X2, which has a clock speed of 1018 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 512-bit bus, and makes use of a 28 nm design. It is made up of 2816 SPUs, 176 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 295X2 should theoretically be a lot better than the Radeon HD 6950 2GB in general. (explain)
Texel RateThe Radeon R9 295X2 is quite a bit (approximately 409%) better at anisotropic filtering than the Radeon HD 6950 2GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 295X2 is a better choice, 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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
