GeForce GTX 1630 vs GeForce GTX 590

Intro

Compare all of that to the GeForce GTX 590, which comes with a clock speed of 607 MHz and a GDDR5 memory speed of 855 MHz. It also makes use of a 384-bit bus, and makes use of a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 590		365 Watts
	Difference: 290 Watts (387%)

Memory Bandwidth

Performance-wise, the GeForce GTX 590 should in theory be quite a bit superior to the GeForce GTX 1630 overall. (explain)

GeForce GTX 590		328320 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 230016 (234%)

Texel Rate

The GeForce GTX 590 will be much (about 40%) better at AF than the GeForce GTX 1630. (explain)

GeForce GTX 590		77696 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 22016 (40%)

Pixel Rate

The GeForce GTX 590 is quite a bit (more or less 109%) faster with regards to full screen anti-aliasing than the GeForce GTX 1630, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 590		58272 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 30432 (109%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 chip could possibly write 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
