Compare any two graphics cards:
Radeon HD 4870 512MB vs Radeon RX 460
IntroThe Radeon HD 4870 512MB uses a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this particular model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon RX 460, which has a clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4870 512MB, in theory, should perform a bit faster than the Radeon RX 460 in general. (explain)
Texel RateThe Radeon RX 460 should be much (more or less 103%) faster with regards to texture filtering than the Radeon HD 4870 512MB. (explain)
Pixel RateThe Radeon RX 460 is a lot (approximately 45%) better at anti-aliasing than the Radeon HD 4870 512MB, and also should be able to handle higher resolutions while still performing well. (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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
