GeForce GTX 1630 vs GeForce GTX 950

Intro

Compare that to the GeForce GTX 950, which has a GPU core clock speed of 1024 MHz, and 2048 MB of GDDR5 RAM set to run at 1652 MHz through a 128-bit bus. It also features 768 SPUs, 48 TAUs, and 32 ROPs.

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950 is the winner, 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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result 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, High Dynamic Range 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 worked out by multiplying the total amount of texture units of the card by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
