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

Intro

The GeForce GT 430 (OEM) uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory runs at a speed of 900 MHz on this card. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Compare those specs to the Radeon HD 6570 (OEM) 1GB, which has a clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

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

Memory Bandwidth

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

Texel Rate

The Radeon HD 6570 (OEM) 1GB is quite a bit (approximately 39%) more effective at 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

If running with a high screen resolution is important to you, then the Radeon HD 6570 (OEM) 1GB is the winner, by far. (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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
