GeForce 8800 GS vs Radeon HD 6450 (OEM)

Intro

Compare those specifications to the Radeon HD 6450 (OEM), which features a clock frequency of 625 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 64-bit bus, and makes use of a 40 nm design. It 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)		31 Watts
GeForce 8800 GS		105 Watts
	Difference: 74 Watts (239%)

Memory Bandwidth

The GeForce 8800 GS, in theory, should be quite a bit faster than the Radeon HD 6450 (OEM) in general. (explain)

GeForce 8800 GS		38400 MB/sec
Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 25600 (200%)

Texel Rate

The GeForce 8800 GS should be quite a bit (more or less 428%) more effective at texture filtering than the Radeon HD 6450 (OEM). (explain)

GeForce 8800 GS		26400 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 21400 (428%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GS is a better choice, by far. (explain)

GeForce 8800 GS		6600 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 4100 (164%)

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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
