Compare any two graphics cards:
Radeon HD 4830 512MB vs Radeon R7 250X
IntroThe Radeon HD 4830 512MB uses a 55 nm design. AMD has set the core frequency at 575 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 640(128x5) SPUs along with 32 TAUs and 16 ROPs.Compare all of that to the Radeon R7 250X, which features GPU core speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the Radeon R7 250X should in theory be a lot better than the Radeon HD 4830 512MB overall. (explain)
Texel RateThe Radeon R7 250X is quite a bit (approximately 117%) faster with regards to anisotropic filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R7 250X is superior to the Radeon HD 4830 512MB, 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 max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
