Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon RX 470
IntroThe Radeon HD 6670 (OEM) 1GB makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon RX 470, which has GPU core speed of 926 MHz, and 8192 MB of GDDR5 RAM set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 470 should theoretically be quite a bit faster than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe Radeon RX 470 should be a lot (about 517%) more effective at anisotropic filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon RX 470 is the winner, by far. (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 max amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 per second. This number is worked out by multiplying the total 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
