GeForce GT 430 vs Radeon HD 5450

Intro

Compare all of that to the Radeon HD 5450, which makes use of a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 memory is set to run at a frequency of 800 MHz on this specific card. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
GeForce GT 430		60 Watts
	Difference: 41 Watts (216%)

Memory Bandwidth

The GeForce GT 430 should in theory be quite a bit faster than the Radeon HD 5450 overall. (explain)

GeForce GT 430		28800 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 16000 (125%)

Texel Rate

The GeForce GT 430 will be much (approximately 115%) faster with regards to anisotropic filtering than the Radeon HD 5450. (explain)

GeForce GT 430		11200 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 6000 (115%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 430 is superior to the Radeon HD 5450, though not by far. (explain)

GeForce GT 430		2800 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 200 (8%)

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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 in one second. This figure is calculated by multiplying the total number of texture units 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 number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
