GeForce GTX 1630 vs GeForce GTX 660

Intro

Compare all of that to the GeForce GTX 660, which comes with clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 960 SPUs along with 80 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 660		140 Watts
	Difference: 65 Watts (87%)

Memory Bandwidth

Performance-wise, the GeForce GTX 660 should in theory be quite a bit superior to the GeForce GTX 1630 in general. (explain)

GeForce GTX 660		144192 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 45888 (47%)

Texel Rate

The GeForce GTX 660 should be a lot (approximately 41%) better at anisotropic filtering than the GeForce GTX 1630. (explain)

GeForce GTX 660		78400 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 22720 (41%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1630 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 660		23520 Mpixels/sec
	Difference: 4320 (18%)

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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
