Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GTS 250 512MB features a GPU core clock speed of 738 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 ROPs.Compare all that to the Radeon HD 6670 (OEM) 1GB, which has a core clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTS 250 512MB should perform just a bit faster than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTS 250 512MB should be quite a bit (more or less 146%) more effective at AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTS 250 512MB 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 max amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of 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.
