Compare any two graphics cards:
Radeon HD 6750 vs Radeon R9 390X 8G
IntroThe Radeon HD 6750 features a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720 SPUs, 36 TAUs, and 16 ROPs.Compare those specs to the Radeon R9 390X 8G, which comes with GPU core speed of 1050 MHz, and 8192 MB of GDDR5 memory set to run at 1500 MHz through a 512-bit bus. It also is comprised of 2816 SPUs, 176 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 390X 8G should be quite a bit faster than the Radeon HD 6750 in general. (explain)
Texel RateThe Radeon R9 390X 8G is much (about 608%) more effective at AF than the Radeon HD 6750. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 390X 8G is a better choice, 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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
