GeForce 9500 GT DDR2 vs Radeon HD 5750 1GB

Intro

Compare those specifications to the Radeon HD 5750 1GB, which has GPU core speed of 700 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
Radeon HD 5750 1GB		86 Watts
	Difference: 36 Watts (72%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB should be 360% quicker than the GeForce 9500 GT DDR2 in general, because of its higher data rate. (explain)

Radeon HD 5750 1GB		73600 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 57600 (360%)

Texel Rate

The Radeon HD 5750 1GB should be quite a bit (about 186%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)

Radeon HD 5750 1GB		25200 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 16400 (186%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is the winner, and very much so. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 6800 (155%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per 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 this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
