Compare any two graphics cards:
Radeon HD 4850 1GB vs Radeon R7 250X 2GB
IntroThe Radeon HD 4850 1GB uses a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR4 RAM works at a frequency of 993 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.Compare all of that to the Radeon R7 250X 2GB, which features clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250X 2GB should be just a bit faster than the Radeon HD 4850 1GB overall. (explain)
Texel RateThe Radeon R7 250X 2GB should be quite a bit (about 60%) faster with regards to AF than the Radeon HD 4850 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many 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.
