GeForce GT 430 vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which comes with core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 should be a lot faster than the GeForce GT 430 in general. (explain)

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

Texel Rate

The Radeon HD 6750 is quite a bit (more or less 133%) better at AF than the GeForce GT 430. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6750 is a better choice, by a large margin. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce GT 430		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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
