GeForce GT 430 1GB vs Radeon HD 5450

Intro

Compare those specs to the Radeon HD 5450, which has core clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

	Difference: 41 Watts (216%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 430 1GB is 125% quicker than the Radeon HD 5450 in general, due to its higher data rate. (explain)

GeForce GT 430 1GB		28800 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 16000 (125%)

Texel Rate

The GeForce GT 430 1GB is quite a bit (more or less 115%) better at anisotropic filtering than the Radeon HD 5450. (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 6000 (115%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 430 1GB is superior to the Radeon HD 5450, though not by far. (explain)

GeForce GT 430 1GB		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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
