GeForce GT 430 (OEM) vs Radeon HD 5450

Intro

Compare those specs to the Radeon HD 5450, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM works at a speed of 800 MHz on this model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the GeForce GT 430 (OEM) should in theory be a lot superior to the Radeon HD 5450 overall. (explain)

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

Texel Rate

The GeForce GT 430 (OEM) should be quite a bit (more or less 115%) better at anisotropic filtering than the Radeon HD 5450. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 430 (OEM) is superior to the Radeon HD 5450, but it probably won't make a huge difference. (explain)

GeForce GT 430 (OEM)		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 (in units of MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
