Compare any two graphics cards:
Radeon HD 4870 512MB vs Radeon RX 560
IntroThe Radeon HD 4870 512MB uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this particular model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon RX 560, which uses a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this specific model. It features 1024 SPUs as well as 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4870 512MB should be 0% quicker than the Radeon RX 560 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon RX 560 will be quite a bit (approximately 151%) more effective at anisotropic filtering than the Radeon HD 4870 512MB. (explain)
Pixel RateThe Radeon RX 560 is quite a bit (more or less 57%) faster with regards to full screen anti-aliasing than the Radeon HD 4870 512MB, and also will be capable of handling higher screen resolutions without losing too much performance. (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 data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units 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 applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
