GeForce 8800 GT 1GB vs GeForce RTX 2070

Intro

Compare all that to the GeForce RTX 2070, which has clock speeds of 1410 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 2304 SPUs as well as 144 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce RTX 2070		175 Watts
	Difference: 70 Watts (67%)

Memory Bandwidth

The GeForce RTX 2070, in theory, should be quite a bit faster than the GeForce 8800 GT 1GB in general. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 401152 (696%)

Texel Rate

The GeForce RTX 2070 should be quite a bit (more or less 504%) more effective at texture filtering than the GeForce 8800 GT 1GB. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 169440 (504%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2070 is the winner, by far. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce 8800 GT 1GB		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 a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
