Compare any two graphics cards:
Radeon HD 4870 2GB vs Radeon R7 260X
IntroThe Radeon HD 4870 2GB uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory works at a speed of 900 MHz on this card. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon R7 260X, which has GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1625 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 4870 2GB should in theory be a small bit superior to the Radeon R7 260X in general. (explain)
Texel RateThe Radeon R7 260X is much (about 105%) more effective at anisotropic filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateThe Radeon R7 260X will be quite a bit (more or less 47%) faster with regards to full screen anti-aliasing than the Radeon HD 4870 2GB, and also able to handle higher resolutions more effectively. (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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core 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 most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
