GeForce GTX 465 vs Radeon HD 6750

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
GeForce GTX 465		200 Watts
	Difference: 114 Watts (133%)

Memory Bandwidth

The GeForce GTX 465 should theoretically perform quite a bit faster than the Radeon HD 6750 in general. (explain)

GeForce GTX 465		102592 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 38592 (60%)

Texel Rate

The GeForce GTX 465 should be just a bit (approximately 2%) faster with regards to AF than the Radeon HD 6750. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 608 (2%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 7824 (67%)

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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
