Compare any two graphics cards:
Radeon HD 6670 (OEM) vs Radeon R9 M270X
IntroThe Radeon HD 6670 (OEM) uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this model. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.Compare that to the Radeon R9 M270X, which comes with a clock speed of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R9 M270X should in theory be a bit better than the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe Radeon R9 M270X will be quite a bit (more or less 51%) faster with regards to texture filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M270X 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: Bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed 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 can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
