GeForce GT 430 vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which comes with GPU core speed of 1650 MHz, and 8192 MB of GDDR6 memory running at 1937 MHz through a 256-bit bus. It also features 3072 SPUs, 192 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 190 Watts (317%)

Memory Bandwidth

Performance-wise, the GeForce RTX 2080 SUPER should in theory be much superior to the GeForce GT 430 overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 479104 (1664%)

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (about 2729%) more effective at AF than the GeForce GT 430. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 305600 (2729%)

Pixel Rate

The GeForce RTX 2080 SUPER should be a lot (more or less 3671%) better at full screen anti-aliasing than the GeForce GT 430, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 102800 (3671%)

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 maximum amount of information (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 clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
