GeForce GT 1030		49152 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 23872 (94%)

Texel Rate

The GeForce GT 1030 is a lot (about 212%) better at AF than the GeForce GT 320. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 27520 (212%)

Pixel Rate

The GeForce GT 1030 is quite a bit (more or less 369%) faster with regards to FSAA than the GeForce GT 320, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 15920 (369%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should 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, HDR 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 calculated by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
