GeForce GT 430 (OEM) vs Radeon HD 3650 256MB

Intro

Compare all of that to the Radeon HD 3650 256MB, which comes with a GPU core clock speed of 725 MHz, and 256 MB of DDR2 memory set to run at 800 MHz through a 128-bit bus. It also is made up of 120(24x5) Stream Processors, 8 Texture Address Units, and 4 ROPs.

GeForce GT 430 (OEM)		11200 Mtexels/sec
Radeon HD 3650 256MB		5800 Mtexels/sec
	Difference: 5400 (93%)

Pixel Rate

The Radeon HD 3650 256MB will be a little bit (more or less 4%) more effective at anti-aliasing than the GeForce GT 430 (OEM), and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 3650 256MB		2900 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 100 (4%)

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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
