Compare any two graphics cards:
GeForce GTX 650 vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GTX 650 features core speeds of 1058 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.
Compare all that to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 650 should theoretically be much better than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTX 650 is much (approximately 76%) better at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 650 is a lot (approximately 165%) more effective at full screen anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and also capable of handling higher screen 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
