Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9400 GT 256MB		50 Watts
GeForce GTX 1050 3GB		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

In theory, the GeForce GTX 1050 3GB should be 572% quicker than the GeForce 9400 GT 256MB in general, because of its greater data rate. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
GeForce 9400 GT 256MB		12800 MB/sec
	Difference: 73216 (572%)

Texel Rate

The GeForce GTX 1050 3GB is much (more or less 1419%) faster with regards to texture filtering than the GeForce 9400 GT 256MB. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce 9400 GT 256MB		4400 Mtexels/sec
	Difference: 62416 (1419%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 3GB is a better choice, by far. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce 9400 GT 256MB		2200 Mpixels/sec
	Difference: 31208 (1419%)

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 (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied in one second. This is calculated by multiplying the total texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
