Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon RX 460 2GB
IntroThe Radeon HD 4830 1GB has a core clock speed of 575 MHz and a GDDR4 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is made up of 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.Compare that to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 460 2GB should perform much faster than the Radeon HD 4830 1GB in general. (explain)
Texel RateThe Radeon RX 460 2GB should be quite a bit (more or less 232%) better at anisotropic filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateThe Radeon RX 460 2GB should be much (about 90%) faster with regards to full screen anti-aliasing than the Radeon HD 4830 1GB, and also 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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
