GeForce 8800 GTX vs GeForce RTX 2070

Intro

Compare all of that to the GeForce RTX 2070, which features a clock frequency of 1410 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit memory bus, and uses a 12 nm design. It is made up of 2304 SPUs, 144 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTX		155 Watts
GeForce RTX 2070		175 Watts
	Difference: 20 Watts (13%)

Memory Bandwidth

The GeForce RTX 2070 should in theory be much faster than the GeForce 8800 GTX in general. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 372352 (431%)

Texel Rate

The GeForce RTX 2070 is quite a bit (about 452%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 166240 (452%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2070 is superior to the GeForce 8800 GTX, and very much so. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 76440 (554%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
