GeForce GT 1030 vs GeForce GT 130

Intro

Compare all of that to the GeForce GT 130, which has a GPU core clock speed of 500 MHz, and 768 MB of DDR2 memory set to run at 250 MHz through a 192-bit bus. It also is comprised of 48 Stream Processors, 24 Texture Address Units, and 16 ROPs.

GeForce GT 130		12000 MB/sec
	Difference: 37152 (310%)

Texel Rate

The GeForce GT 1030 will be much (approximately 237%) better at anisotropic filtering than the GeForce GT 130. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 28480 (237%)

Pixel Rate

The GeForce GT 1030 should be a lot (about 153%) faster with regards to AA than the GeForce GT 130, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 12240 (153%)

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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
