GeForce 9400 GT 256MB vs GeForce GTX 1050 Ti

Intro

Compare those specs to the GeForce GTX 1050 Ti, which has a clock speed of 1290 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It is made up of 768 SPUs, 48 TAUs, and 32 Raster Operation Units.

GeForce GTX 1050 Ti		114688 MB/sec
GeForce 9400 GT 256MB		12800 MB/sec
	Difference: 101888 (796%)

Texel Rate

The GeForce GTX 1050 Ti should be a lot (approximately 1307%) more effective at anisotropic filtering than the GeForce 9400 GT 256MB. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
GeForce 9400 GT 256MB		4400 Mtexels/sec
	Difference: 57520 (1307%)

Pixel Rate

The GeForce GTX 1050 Ti will be quite a bit (about 1776%) better at FSAA than the GeForce 9400 GT 256MB, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
GeForce 9400 GT 256MB		2200 Mpixels/sec
	Difference: 39080 (1776%)

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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR 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 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 most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
