GeForce 9600 GT 1GB vs Radeon HD 6450 (OEM) 1GB

Intro

Compare all that to the Radeon HD 6450 (OEM) 1GB, which comes with GPU core speed of 750 MHz, and 1024 MB of GDDR5 memory running at 900 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6450 (OEM) 1GB		31 Watts
GeForce 9600 GT 1GB		95 Watts
	Difference: 64 Watts (206%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GT 1GB should be 100% faster than the Radeon HD 6450 (OEM) 1GB in general, due to its higher bandwidth. (explain)

GeForce 9600 GT 1GB		57600 MB/sec
Radeon HD 6450 (OEM) 1GB		28800 MB/sec
	Difference: 28800 (100%)

Texel Rate

The GeForce 9600 GT 1GB is a lot (more or less 247%) better at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)

GeForce 9600 GT 1GB		20800 Mtexels/sec
Radeon HD 6450 (OEM) 1GB		6000 Mtexels/sec
	Difference: 14800 (247%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9600 GT 1GB is the winner, and very much so. (explain)

GeForce 9600 GT 1GB		10400 Mpixels/sec
Radeon HD 6450 (OEM) 1GB		3000 Mpixels/sec
	Difference: 7400 (247%)

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 (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 bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 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 number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
