GeForce GT 1030		49152 MB/sec
	Difference: 3840 (8%)

Texel Rate

The GeForce GT 1030 is quite a bit (more or less 279%) faster with regards to AF than the Radeon HD 3850 1GB. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 3850 1GB		10688 Mtexels/sec
	Difference: 29792 (279%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 1030 is the winner, and very much so. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 3850 1GB		10688 Mpixels/sec
	Difference: 9552 (89%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If 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 are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
