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

Intro

Compare all that to the Radeon HD 6570 (OEM) 1GB, which has a GPU core clock speed of 650 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation 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 memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB will be much (more or less 39%) better at anisotropic filtering 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 should be a lot (about 86%) faster with regards to FSAA than the GeForce GT 430 (OEM), and will be capable of handling higher resolutions without slowing down too much. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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.
