Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 6670 (OEM)
IntroThe GeForce GTS 250 512MB makes use of a 65/55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 memory runs at a speed of 1100 MHz on this particular model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 6670 (OEM), which has a clock frequency of 800 MHz and a GDDR5 memory frequency 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 BandwidthAs far as performance goes, the GeForce GTS 250 512MB should in theory be a little bit better than the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe GeForce GTS 250 512MB should be quite a bit (approximately 146%) more effective at anisotropic filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTS 250 512MB 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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
