GeForce GTX 1630 vs GeForce GTX 480

Intro

Compare those specifications to the GeForce GTX 480, which uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR5 memory is set to run at a frequency of 924 MHz on this particular card. It features 480 SPUs along with 60 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 480		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically, the GeForce GTX 480 should be a lot faster than the GeForce GTX 1630 in general. (explain)

GeForce GTX 480		177408 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 79104 (80%)

Texel Rate

The GeForce GTX 1630 will be quite a bit (about 33%) better at anisotropic filtering than the GeForce GTX 480. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 13680 (33%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 480 is a better choice, by a large margin. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 5760 (21%)

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 (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
