Compare any two graphics cards:
VS

GeForce GT 430 (OEM) vs Radeon HD 6570 (OEM) 1GB

Intro

The GeForce GT 430 (OEM) comes with a GPU clock speed of 700 MHz, and the 2048 MB of GDDR3 RAM runs at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular card. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6570 (OEM) 1GB 50 Watts
GeForce GT 430 (OEM) 60 Watts
Difference: 10 Watts (20%)

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB is much (approximately 39%) faster with regards to AF than the GeForce GT 430 (OEM). (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
GeForce GT 430 (OEM) 11200 Mtexels/sec
Difference: 4400 (39%)

Pixel Rate

The Radeon HD 6570 (OEM) 1GB is a lot (approximately 86%) faster with regards to full screen anti-aliasing than the GeForce GT 430 (OEM), and also able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 6570 (OEM) 1GB 5200 Mpixels/sec
GeForce GT 430 (OEM) 2800 Mpixels/sec
Difference: 2400 (86%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
