Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 9800 GT 1GB comes with a GPU core clock speed of 600 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 112 Stream Processors, 56 TAUs, and 16 ROPs.
Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which has a core clock frequency of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6570 (OEM) 2GB should perform a bit faster than the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 1GB is quite a bit (about 115%) faster with regards to AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 9800 GT 1GB is superior to the Radeon HD 6570 (OEM) 2GB, by far. (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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling 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 that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
