GeForce GTX 1630 vs GeForce GTX 580

Intro

Compare all of that to the GeForce GTX 580, which comes with a core clock speed of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 384-bit bus, and makes use of a 40 nm design. It features 512 SPUs, 64 Texture Address Units, and 48 ROPs.

GeForce GTX 580		49408 Mtexels/sec
	Difference: 6272 (13%)

Pixel Rate

The GeForce GTX 580 should be a lot (more or less 33%) better at FSAA than the GeForce GTX 1630, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 580		37056 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 9216 (33%)

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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
