Compare any two graphics cards:
Radeon HD 5830 vs Radeon R9 295X2
IntroThe Radeon HD 5830 makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific model. It features 1120(224x5) SPUs along with 56 TAUs and 16 ROPs.Compare those specifications to the Radeon R9 295X2, which features a core clock frequency of 1018 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 512-bit bus, and makes use of a 28 nm design. It is comprised of 2816 SPUs, 176 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 295X2 should theoretically be quite a bit better than the Radeon HD 5830 overall. (explain)
Texel RateThe Radeon R9 295X2 should be much (approximately 700%) faster with regards to anisotropic filtering than the Radeon HD 5830. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 295X2 is superior to the Radeon HD 5830, 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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
