Compare any two graphics cards:
Radeon HD 5670 vs Radeon R9 M380
IntroThe Radeon HD 5670 makes use of a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon R9 M380, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1500 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R9 M380 should in theory be much better than the Radeon HD 5670 in general. (explain)
Texel RateThe Radeon R9 M380 is a lot (more or less 158%) faster with regards to texture filtering than the Radeon HD 5670. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 M380 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: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock 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 one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
