GeForce GT 450 (OEM) vs GeForce RTX 2080 SUPER

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 144 Watts (136%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER will be 429% faster than the GeForce GT 450 (OEM) in general, due to its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 411904 (429%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (more or less 1571%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 297840 (1571%)

Pixel Rate

The GeForce RTX 2080 SUPER is a lot (more or less 457%) faster with regards to anti-aliasing than the GeForce GT 450 (OEM), and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 86640 (457%)

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 over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
