GeForce GTX 1630 vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1024 MHz. The GDDR5 RAM runs at a speed of 1652 MHz on this specific card. It features 768 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 950		90 Watts
	Difference: 15 Watts (20%)

Memory Bandwidth

The GeForce GTX 950, in theory, should be just a bit faster than the GeForce GTX 1630 overall. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 7424 (8%)

Texel Rate

The GeForce GTX 1630 should be a bit (about 13%) more effective at texture filtering than the GeForce GTX 950. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 950 is a better choice, but it probably won't make a huge difference. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
