Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 6670 (OEM)
IntroThe GeForce GTS 450 1GB comes with a GPU core speed of 783 MHz, and the 1024 MB of GDDR5 RAM runs at 902 MHz through a 128-bit bus. It also is comprised of 192 SPUs, 32 TAUs, and 16 ROPs.
Compare that to the Radeon HD 6670 (OEM), which has clock speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 6670 (OEM) should theoretically be just a bit superior to the GeForce GTS 450 1GB overall. (explain)
Texel RateThe GeForce GTS 450 1GB will be much (more or less 31%) more effective at anisotropic filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe GeForce GTS 450 1GB is much (approximately 96%) more effective at anti-aliasing than the Radeon HD 6670 (OEM), and should be capable of handling higher 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
