Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
Radeon HD 6750		86 Watts
	Difference: 11 Watts (15%)

Memory Bandwidth

In theory, the Radeon RX 460 2GB is 75% faster than the Radeon HD 6750 overall, because of its greater bandwidth. (explain)

Radeon RX 460 2GB		112000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 48000 (75%)

Texel Rate

The Radeon RX 460 2GB is quite a bit (about 134%) faster with regards to anisotropic filtering than the Radeon HD 6750. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 34940 (134%)

Pixel Rate

The Radeon RX 460 2GB should be a lot (more or less 50%) faster with regards to full screen anti-aliasing than the Radeon HD 6750, and also should be able to handle higher screen resolutions better. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 5840 (50%)

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 information (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
