GeForce GT 1030 vs GeForce GTX 660

Intro

Compare those specs to the GeForce GTX 660, which has core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 960 SPUs along with 80 Texture Address Units and 24 ROPs.

GeForce GT 1030		49152 MB/sec
	Difference: 95040 (193%)

Texel Rate

The GeForce GTX 660 will be quite a bit (about 94%) more effective at texture filtering than the GeForce GT 1030. (explain)

GeForce GTX 660		78400 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 37920 (94%)

Pixel Rate

The GeForce GTX 660 is a little bit (approximately 16%) better at FSAA than the GeForce GT 1030, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 660		23520 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 3280 (16%)

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: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
