GeForce GTX 1630 vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which uses a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this card. It features 1344 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Geforce GTX 670		170 Watts
	Difference: 95 Watts (127%)

Memory Bandwidth

The Geforce GTX 670 should in theory perform much faster than the GeForce GTX 1630 in general. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 93696 (95%)

Texel Rate

The Geforce GTX 670 should be a lot (more or less 84%) faster with regards to texture filtering than the GeForce GTX 1630. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 46800 (84%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 670 is a better choice, not by a very large margin though. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 1440 (5%)

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 information (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the 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 maximum number of pixels the video card can possibly record to the local memory in one 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
