GeForce GTX 1630 vs GeForce GTX 650

Intro

The GeForce GTX 1630 uses a 12 nm design. nVidia has set the core frequency at 1740 MHz. The GDDR6 RAM runs at a frequency of 1500 MHz on this specific card. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare that to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core frequency at 1058 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this card. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 650 80000 MB/sec
Difference: 18304 (23%)

Texel Rate

The GeForce GTX 1630 should be a lot (approximately 64%) faster with regards to anisotropic filtering than the GeForce GTX 650. (explain)

GeForce GTX 1630 55680 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 21824 (64%)

Pixel Rate

The GeForce GTX 1630 will be quite a bit (more or less 64%) faster with regards to full screen anti-aliasing than the GeForce GTX 650, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 1630 27840 Mpixels/sec
GeForce GTX 650 16928 Mpixels/sec
Difference: 10912 (64%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the 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 video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
