Compare any two graphics cards:
GeForce GT 430 (OEM) vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GT 430 (OEM) uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.
Compare all that to the Radeon HD 6570 (OEM) 2GB, which features GPU core speed of 650 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6570 (OEM) 2GB should theoretically be much better than the GeForce GT 430 (OEM) in general. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB will be quite a bit (about 39%) faster with regards to anisotropic filtering than the GeForce GT 430 (OEM). (explain)
Pixel RateThe Radeon HD 6570 (OEM) 2GB is a lot (more or less 86%) faster with regards to AA than the GeForce GT 430 (OEM), and will be able to handle higher 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 (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
