GeForce GT 430 (OEM) vs Radeon HD 7750

Intro

Compare that to the Radeon HD 7750, which comes with core clock speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 RAM. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
GeForce GT 430 (OEM)		60 Watts
	Difference: 5 Watts (9%)

Memory Bandwidth

Performance-wise, the Radeon HD 7750 should in theory be quite a bit superior to the GeForce GT 430 (OEM) overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 43200 (150%)

Texel Rate

The Radeon HD 7750 will be much (more or less 129%) faster with regards to anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 14400 (129%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 7750 is superior to the GeForce GT 430 (OEM), and very much so. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 10000 (357%)

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 max amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, 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 most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
