Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 6670 (OEM)
IntroThe GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 memory is set to run at a frequency of 1100 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.Compare all of that to the Radeon HD 6670 (OEM), which comes with a GPU core clock speed of 800 MHz, and 512 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTS 250 1GB should be a little bit faster than the Radeon HD 6670 (OEM) overall. (explain)
Texel RateThe GeForce GTS 250 1GB will be much (approximately 146%) better at AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe GeForce GTS 250 1GB is much (more or less 85%) better at full screen anti-aliasing than the Radeon HD 6670 (OEM), and able to handle higher screen resolutions better. (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 information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount 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 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
