GeForce 9600 GSO 768MB vs Radeon HD 6750

Intro

Compare all that to the Radeon HD 6750, which has a core clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

GeForce 9600 GSO 768MB		84 Watts
Radeon HD 6750		86 Watts
	Difference: 2 Watts (2%)

Memory Bandwidth

In theory, the Radeon HD 6750 should be much faster than the GeForce 9600 GSO 768MB overall. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce 9600 GSO 768MB is just a bit (about 1%) better at texture filtering than the Radeon HD 6750. (explain)

GeForce 9600 GSO 768MB		26400 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 300 (1%)

Pixel Rate

The Radeon HD 6750 is a lot (about 76%) better at AA than the GeForce 9600 GSO 768MB, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 5000 (76%)

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 megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
