Texel Rate

The Radeon HD 6970 should be much (approximately 109%) faster with regards to anisotropic filtering than the GeForce GT 1030. (explain)

Radeon HD 6970		84480 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 44000 (109%)

Pixel Rate

The Radeon HD 6970 is much (more or less 39%) more effective at FSAA than the GeForce GT 1030, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 6970		28160 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 7920 (39%)

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 (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
