Compare any two graphics cards:
Radeon HD 4850 1GB vs Radeon R7 250X 2GB
IntroThe Radeon HD 4850 1GB makes use of a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR4 memory runs at a speed of 993 MHz on this specific model. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.Compare all of that to the Radeon R7 250X 2GB, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R7 250X 2GB should perform a little bit faster than the Radeon HD 4850 1GB in general. (explain)
Texel RateThe Radeon R7 250X 2GB should be a lot (about 60%) better at texture filtering than the Radeon HD 4850 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R7 250X 2GB is a better choice, 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
