Compare any two graphics cards:
Radeon HD 4730 vs Radeon R9 390X 8G
IntroThe Radeon HD 4730 comes with a clock speed of 700 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon R9 390X 8G, which has clock speeds of 1050 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 RAM. It features 2816 SPUs along with 176 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 390X 8G should theoretically be much better than the Radeon HD 4730 in general. (explain)
Texel RateThe Radeon R9 390X 8G is a lot (approximately 725%) better at texture filtering than the Radeon HD 4730. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 390X 8G is a better choice, by a large margin. (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 information (measured in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one 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 graphics 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 that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
