GeForce GT 430 1GB vs Radeon HD 5670

Intro

Compare those specs to the Radeon HD 5670, which makes use of a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 4300 (38%)

Pixel Rate

The Radeon HD 5670 should be much (about 121%) more effective at FSAA than the GeForce GT 430 1GB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 5670		6200 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 3400 (121%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
