GeForce GTX 1630 vs GeForce GTX 470

Intro

Compare all that to the GeForce GTX 470, which comes with a GPU core clock speed of 607 MHz, and 1280 MB of GDDR5 RAM running at 837 MHz through a 320-bit bus. It also features 448 Stream Processors, 56 TAUs, and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 470		215 Watts
	Difference: 140 Watts (187%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 470 should perform quite a bit faster than the GeForce GTX 1630 in general. (explain)

GeForce GTX 470		133920 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 35616 (36%)

Texel Rate

The GeForce GTX 1630 will be much (about 64%) better at texture filtering than the GeForce GTX 470. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 21688 (64%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1630 is the winner, but not by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 470		24280 Mpixels/sec
	Difference: 3560 (15%)

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 data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
