GeForce GTX 470 vs Radeon HD 6750

Intro

Compare all that to the Radeon HD 6750, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Radeon HD 6750		86 Watts
GeForce GTX 470		215 Watts
	Difference: 129 Watts (150%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 470 should perform much faster than the Radeon HD 6750 overall. (explain)

GeForce GTX 470		133920 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 69920 (109%)

Texel Rate

The GeForce GTX 470 is a lot (about 30%) more effective at texture filtering than the Radeon HD 6750. (explain)

GeForce GTX 470		33992 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 7892 (30%)

Pixel Rate

The GeForce GTX 470 should be quite a bit (more or less 109%) more effective at FSAA than the Radeon HD 6750, and also able to handle higher resolutions while still performing well. (explain)

GeForce GTX 470		24280 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 12680 (109%)

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 transported across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
