GeForce GT 430 vs Radeon HD 6450 (OEM) 1GB

Intro

Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which comes with GPU clock speed of 750 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 64-bit bus. It also is made up of 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6450 (OEM) 1GB		31 Watts
GeForce GT 430		60 Watts
	Difference: 29 Watts (94%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce GT 430 will be a lot (more or less 87%) better at AF than the Radeon HD 6450 (OEM) 1GB. (explain)

GeForce GT 430		11200 Mtexels/sec
Radeon HD 6450 (OEM) 1GB		6000 Mtexels/sec
	Difference: 5200 (87%)

Pixel Rate

The Radeon HD 6450 (OEM) 1GB should be a small bit (about 7%) better at FSAA than the GeForce GT 430, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 6450 (OEM) 1GB		3000 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 200 (7%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
