Radeon HD 6750 1GB		64000 MB/sec
	Difference: 50688 (79%)

Texel Rate

The GeForce GTX 1050 is a lot (approximately 108%) faster with regards to texture filtering than the Radeon HD 6750 1GB. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 28060 (108%)

Pixel Rate

The GeForce GTX 1050 is quite a bit (more or less 274%) more effective at anti-aliasing than the Radeon HD 6750 1GB, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 31728 (274%)

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 max amount of information (counted in megabytes per second) that can be transferred over 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 type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
