Radeon HD 6670 (OEM) 1GB		64000 MB/sec
	Difference: 50688 (79%)

Texel Rate

The GeForce GTX 1050 is quite a bit (more or less 182%) more effective at AF than the Radeon HD 6670 (OEM) 1GB. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 6670 (OEM) 1GB		19200 Mtexels/sec
	Difference: 34960 (182%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 is the winner, by a large margin. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 6670 (OEM) 1GB		6400 Mpixels/sec
	Difference: 36928 (577%)

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 max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, 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 maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
