GeForce GT 430 1GB vs Radeon HD 6750

Intro

Compare those specs to the Radeon HD 6750, which makes use of a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific model. 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 1GB		60 Watts
Radeon HD 6750		86 Watts
	Difference: 26 Watts (43%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 should be quite a bit faster than the GeForce GT 430 1GB overall. (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 a lot (approximately 133%) better at anisotropic filtering 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 a lot (more or less 314%) more effective at FSAA than the GeForce GT 430 1GB, and will be capable of handling higher resolutions without slowing down too much. (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 data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
