GeForce GT 430 1GB vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which comes with a GPU core clock speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
Radeon HD 6750		86 Watts
	Difference: 26 Watts (43%)

Memory Bandwidth

Theoretically, the Radeon HD 6750 should perform quite a bit faster than the GeForce GT 430 1GB in general. (explain)

Radeon HD 6750		64000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The Radeon HD 6750 should be much (approximately 133%) more effective at AF than the GeForce GT 430 1GB. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 14900 (133%)

Pixel Rate

The Radeon HD 6750 is much (about 314%) faster with regards to FSAA than the GeForce GT 430 1GB, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 8800 (314%)

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 (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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