GeForce 9600 GSO 512MB vs Radeon HD 5450

Intro

Compare those specs to the Radeon HD 5450, which has GPU clock speed of 650 MHz, and 512 MB of DDR3 memory set to run at 800 MHz through a 64-bit bus. It also features 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Radeon HD 5450		5200 Mtexels/sec
	Difference: 26000 (500%)

Pixel Rate

The GeForce 9600 GSO 512MB should be a lot (about 300%) faster with regards to FSAA than the Radeon HD 5450, and capable of handling 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 largest amount of data (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card 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 most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
