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 clocked the core frequency at 738 MHz. The GDDR3 RAM runs at a frequency of 1100 MHz on this specific model. It features 128 SPUs as well as 64 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6670 (OEM), which features core speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 250 512MB should theoretically be a bit superior to the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe GeForce GTS 250 512MB will be much (more or less 146%) faster with regards to texture filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTS 250 512MB is a better choice, by a large margin. (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 information (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
