Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon R9 M275X
IntroThe Radeon HD 6670 (OEM) 1GB features a GPU clock speed of 800 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon R9 M275X, which makes use of a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 M275X should in theory be a little bit better than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe Radeon R9 M275X should be a lot (approximately 88%) better at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 M275X is superior to the Radeon HD 6670 (OEM) 1GB, and very much so. (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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
