Texel Rate

The Radeon RX 470 4GB should be a lot (more or less 222%) better at texture filtering than the GeForce GTX 260. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 81664 (222%)

Pixel Rate

The Radeon RX 470 4GB is much (approximately 84%) better at full screen anti-aliasing than the GeForce GTX 260, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 13504 (84%)

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 maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
