GeForce 8800 GTX vs GeForce RTX 2080 SUPER

Intro

Compare all of that to the GeForce RTX 2080 SUPER, which has GPU core speed of 1650 MHz, and 8192 MB of GDDR6 memory set to run at 1937 MHz through a 256-bit bus. It also is made up of 3072 Stream Processors, 192 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTX		155 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 95 Watts (61%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER is 488% faster than the GeForce 8800 GTX overall, due to its greater data rate. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 421504 (488%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (more or less 761%) more effective at AF than the GeForce 8800 GTX. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 280000 (761%)

Pixel Rate

The GeForce RTX 2080 SUPER is quite a bit (approximately 665%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTX, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 91800 (665%)

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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 the texel rate, the better the video card will be at 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
