GeForce GTX 1050 3GB vs GeForce GTX 950

Intro

Compare all that to the GeForce GTX 950, which features GPU clock speed of 1024 MHz, and 2048 MB of GDDR5 memory set to run at 1652 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 48 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 3GB		75 Watts
GeForce GTX 950		90 Watts
	Difference: 15 Watts (20%)

Memory Bandwidth

In theory, the GeForce GTX 950 should be 23% quicker than the GeForce GTX 1050 3GB in general, because of its higher data rate. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 19712 (23%)

Texel Rate

The GeForce GTX 1050 3GB will be a lot (about 36%) more effective at anisotropic filtering than the GeForce GTX 950. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 17664 (36%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1050 3GB is superior to the GeForce GTX 950, though not by far. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce GTX 950		32768 Mpixels/sec
	Difference: 640 (2%)

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 information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
