Compare any two graphics cards:
Radeon HD 4870 2GB vs Radeon R7 260X
IntroThe Radeon HD 4870 2GB has a GPU core speed of 750 MHz, and the 2048 MB of GDDR5 memory is set to run at 900 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon R7 260X, which makes use of a 28 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1625 MHz on this card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4870 2GB should in theory perform a small bit faster than the Radeon R7 260X overall. (explain)
Texel RateThe Radeon R7 260X is a lot (about 105%) more effective at texture filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateThe Radeon R7 260X will be quite a bit (approximately 47%) faster with regards to anti-aliasing than the Radeon HD 4870 2GB, and able to handle higher resolutions without slowing down too much. (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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
