GeForce 9600 GSO 512MB vs Radeon HD 5450

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
GeForce 9600 GSO 512MB		90 Watts
	Difference: 71 Watts (374%)

Memory Bandwidth

In theory, the GeForce 9600 GSO 512MB will be 350% faster than the Radeon HD 5450 in general, due to its greater bandwidth. (explain)

GeForce 9600 GSO 512MB		57600 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 44800 (350%)

Texel Rate

The GeForce 9600 GSO 512MB should be a lot (more or less 500%) better at texture filtering than the Radeon HD 5450. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 26000 (500%)

Pixel Rate

The GeForce 9600 GSO 512MB should be much (more or less 300%) faster with regards to full screen anti-aliasing than the Radeon HD 5450, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce 9600 GSO 512MB		10400 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 7800 (300%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 rate is also dependant on quite a few 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.
