GeForce GT 430 1GB vs Radeon HD 4350

Intro

Compare all that to the Radeon HD 4350, which features GPU clock speed of 575 MHz, and 512 MB of DDR2 RAM running at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Theoretically speaking, the GeForce GT 430 1GB should be 260% faster than the Radeon HD 4350 overall, due to its higher data rate. (explain)

GeForce GT 430 1GB		28800 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 20800 (260%)

Texel Rate

The GeForce GT 430 1GB will be a lot (approximately 143%) more effective at texture filtering than the Radeon HD 4350. (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 6600 (143%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 430 1GB is superior to the Radeon HD 4350, and very much so. (explain)

GeForce GT 430 1GB		2800 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 500 (22%)

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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
