GeForce 8800 GT 512MB vs GeForce RTX 2070

Intro

Compare all that to the GeForce RTX 2070, which features GPU clock speed of 1410 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 64 Raster Operation Units.

GeForce 8800 GT 512MB		105 Watts
GeForce RTX 2070		175 Watts
	Difference: 70 Watts (67%)

Memory Bandwidth

Theoretically, the GeForce RTX 2070 should perform quite a bit faster than the GeForce 8800 GT 512MB in general. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 401152 (696%)

Texel Rate

The GeForce RTX 2070 should be much (more or less 504%) more effective at texture filtering than the GeForce 8800 GT 512MB. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 169440 (504%)

Pixel Rate

The GeForce RTX 2070 should be a lot (approximately 840%) more effective at full screen anti-aliasing than the GeForce 8800 GT 512MB, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 80640 (840%)

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 data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
