Compare any two graphics cards:
Radeon HD 4870 1GB vs Radeon R9 380 4G
IntroThe Radeon HD 4870 1GB makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM runs at a speed of 900 MHz on this card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon R9 380 4G, which features a core clock frequency of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 380 4G should theoretically perform a lot faster than the Radeon HD 4870 1GB in general. (explain)
Texel RateThe Radeon R9 380 4G is a lot (about 262%) more effective at texture filtering than the Radeon HD 4870 1GB. (explain)
Pixel RateThe Radeon R9 380 4G is much (about 159%) better at full screen anti-aliasing than the Radeon HD 4870 1GB, and also capable of handling higher screen resolutions better. (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 (counted in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling 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 graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends 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 maximum fill rate.
