Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce 9600 GT 512MB has a GPU core speed of 650 MHz, and the 512 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is made up of 64 SPUs, 32 TAUs, and 16 Raster Operation Units.
Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. ATi has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6670 (OEM) 1GB should theoretically perform a bit faster than the GeForce 9600 GT 512MB in general. (explain)
Texel RateThe GeForce 9600 GT 512MB will be a little bit (approximately 8%) more effective at AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe GeForce 9600 GT 512MB is quite a bit (about 63%) better at AA than the Radeon HD 6670 (OEM) 1GB, and also will be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
