GeForce GT 430 1GB vs Radeon HD 5750 512MB

Intro

Compare all that to the Radeon HD 5750 512MB, which comes with GPU clock speed of 700 MHz, and 512 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

GeForce GT 430 1GB		60 Watts
Radeon HD 5750 512MB		86 Watts
	Difference: 26 Watts (43%)

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 512MB should in theory be much superior to the GeForce GT 430 1GB overall. (explain)

Radeon HD 5750 512MB		73600 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 44800 (156%)

Texel Rate

The Radeon HD 5750 512MB is quite a bit (about 125%) faster with regards to anisotropic filtering than the GeForce GT 430 1GB. (explain)

Radeon HD 5750 512MB		25200 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 14000 (125%)

Pixel Rate

The Radeon HD 5750 512MB should be a lot (more or less 300%) better at FSAA than the GeForce GT 430 1GB, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 5750 512MB		11200 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 8400 (300%)

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 data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
