GeForce GTX 1630 vs GeForce GTX 570

Intro

Compare all of that to the GeForce GTX 570, which has core speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 RAM. It features 480 SPUs along with 60 TAUs and 40 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 570		219 Watts
	Difference: 144 Watts (192%)

Memory Bandwidth

In theory, the GeForce GTX 570 is 55% faster than the GeForce GTX 1630 overall, because of its higher data rate. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 53696 (55%)

Texel Rate

The GeForce GTX 1630 should be a lot (about 27%) more effective at texture filtering than the GeForce GTX 570. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 11760 (27%)

Pixel Rate

The GeForce GTX 570 will be a little bit (about 5%) more effective at FSAA than the GeForce GTX 1630, and also will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 570		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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 reach the maximum fill rate.
