GeForce 9600 GSO 1.5GB vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 512 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
GeForce 9600 GSO 1.5GB		84 Watts
	Difference: 29 Watts (53%)

Memory Bandwidth

The Radeon HD 7750 should in theory be much faster than the GeForce 9600 GSO 1.5GB overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 9600 GSO 1.5GB		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The GeForce 9600 GSO 1.5GB should be a small bit (more or less 3%) faster with regards to texture filtering than the Radeon HD 7750. (explain)

GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 800 (3%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 7750 is superior to the GeForce 9600 GSO 1.5GB, and very much so. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 9600 GSO 1.5GB		6600 Mpixels/sec
	Difference: 6200 (94%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface 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 ANOTHER 2x. The better the card's memory bandwidth, the better 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 are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
