Compare any two graphics cards:
Radeon HD 5870 vs Radeon R9 290
IntroThe Radeon HD 5870 comes with a GPU clock speed of 850 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1200 MHz through a 256-bit bus. It also is made up of 1600(320x5) Stream Processors, 80 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon R9 290, which makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this specific card. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 290 should be 108% faster than the Radeon HD 5870 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon R9 290 will be quite a bit (approximately 88%) more effective at anisotropic filtering than the Radeon HD 5870. (explain)
Pixel RateThe Radeon R9 290 should be much (approximately 88%) better at anti-aliasing than the Radeon HD 5870, and also will be capable of handling higher screen resolutions more effectively. (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: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
