GeForce GT 1030 vs GeForce GTX 660 Ti

Intro

Compare those specifications to the GeForce GTX 660 Ti, which has a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 memory set to run at 1500 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 Texture Address Units, and 24 Raster Operation Units.

GeForce GT 1030		49152 MB/sec
	Difference: 94848 (193%)

Texel Rate

The GeForce GTX 660 Ti is much (about 153%) better at anisotropic filtering than the GeForce GT 1030. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 62000 (153%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 660 Ti is the winner, not by a very large margin though. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 1720 (8%)

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 (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
