Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 5750 1GB uses a 40 nm design. ATi has set the core speed at 700 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this card. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which features a core clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5750 1GB should theoretically be just a bit faster than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 5750 1GB will be quite a bit (approximately 31%) faster with regards to texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 5750 1GB will be much (about 75%) more effective at FSAA than the Radeon HD 6670 (OEM) 1GB, and will be able to handle higher resolutions more effectively. (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.

Specifications
Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
