Compare any two graphics cards:
Radeon HD 4850 1GB vs Radeon R9 280X
IntroThe Radeon HD 4850 1GB has a GPU core speed of 625 MHz, and the 1024 MB of GDDR4 memory runs at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.Compare that to the Radeon R9 280X, which uses a 28 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 280X should perform quite a bit faster than the Radeon HD 4850 1GB in general. (explain)
Texel RateThe Radeon R9 280X will be much (approximately 335%) faster with regards to AF than the Radeon HD 4850 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 280X is superior to the Radeon HD 4850 1GB, 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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to 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 get to the max fill rate.
