Compare any two graphics cards:
Radeon HD 5870 vs Radeon RX 470 4GB
IntroThe Radeon HD 5870 uses a 40 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this specific model. It features 1600(320x5) SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon RX 470 4GB, which has core clock speeds of 926 MHz on the GPU, and 1650 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 470 4GB will be 38% faster than the Radeon HD 5870 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon RX 470 4GB is quite a bit (about 74%) better at AF than the Radeon HD 5870. (explain)
Pixel RateThe Radeon RX 470 4GB should be a bit (approximately 9%) faster with regards to full screen anti-aliasing than the Radeon HD 5870, and should be able to handle higher 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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the bandwidth is, the lower the ability to reach the max fill rate.
