GeForce GT 1030		49152 MB/sec
	Difference: 142848 (291%)

Texel Rate

The Geforce GTX 670 should be quite a bit (approximately 153%) more effective at anisotropic filtering than the GeForce GT 1030. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 62000 (153%)

Pixel Rate

The Geforce GTX 670 will be a lot (approximately 45%) better at full screen anti-aliasing than the GeForce GT 1030, and also should be capable of handling higher screen resolutions better. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 9040 (45%)

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 (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a 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. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
