GeForce GTX 1630 vs GeForce GTX 950

Intro

Compare those specifications to the GeForce GTX 950, which features core clock speeds of 1024 MHz on the GPU, and 1652 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 6528 (13%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950 is superior to the GeForce GTX 1630, though only just barely. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 4928 (18%)

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 (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
