GeForce 9400 GT 256MB vs GeForce RTX 2080 SUPER

Intro

Compare those specs to the GeForce RTX 2080 SUPER, which makes use of a 12 nm design. nVidia has set the core frequency at 1650 MHz. The GDDR6 memory runs at a frequency of 1937 MHz on this card. It features 3072 SPUs along with 192 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9400 GT 256MB		50 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 200 Watts (400%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER will be 3868% faster than the GeForce 9400 GT 256MB overall, because of its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce 9400 GT 256MB		12800 MB/sec
	Difference: 495104 (3868%)

Texel Rate

The GeForce RTX 2080 SUPER will be quite a bit (more or less 7100%) more effective at anisotropic filtering than the GeForce 9400 GT 256MB. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce 9400 GT 256MB		4400 Mtexels/sec
	Difference: 312400 (7100%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is the winner, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce 9400 GT 256MB		2200 Mpixels/sec
	Difference: 103400 (4700%)

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 (in units of megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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