GeForce GTS 150		32000 MB/sec
	Difference: 179200 (560%)

Texel Rate

The Radeon RX 470 is a lot (more or less 150%) faster with regards to AF than the GeForce GTS 150. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 71168 (150%)

Pixel Rate

The Radeon RX 470 is quite a bit (about 150%) better at FSAA than the GeForce GTS 150, and capable of handling higher resolutions while still performing well. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 17792 (150%)

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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
