GeForce GT 1030		30 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 80 Watts (267%)

Memory Bandwidth

Performance-wise, the GeForce GTX 650 Ti 2GB should theoretically be quite a bit superior to the GeForce GT 1030 in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 37248 (76%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be much (more or less 47%) more effective at texture filtering than the GeForce GT 1030. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 18912 (47%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 1030 is a better choice, by far. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 5392 (36%)

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 (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
