Compare any two graphics cards:
Radeon HD 5870 vs Radeon R7 250X 2GB
IntroThe Radeon HD 5870 makes use of a 40 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this specific card. It features 1600(320x5) SPUs as well as 80 TAUs and 32 Rasterization Operator Units.Compare all that to the Radeon R7 250X 2GB, which features a GPU core clock speed of 1000 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5870 should be quite a bit faster than the Radeon R7 250X 2GB in general. (explain)
Texel RateThe Radeon HD 5870 should be a lot (approximately 70%) more effective at AF than the Radeon R7 250X 2GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 5870 is the winner, and very much so. (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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units 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 processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
