GeForce 8600 GT 512MB DDR2 vs GeForce RTX 2070

Intro

Compare those specifications to the GeForce RTX 2070, which uses a 12 nm design. nVidia has set the core frequency at 1410 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this particular card. It features 2304 SPUs along with 144 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
GeForce RTX 2070		175 Watts
	Difference: 128 Watts (272%)

Memory Bandwidth

In theory, the GeForce RTX 2070 should be 3484% faster than the GeForce 8600 GT 512MB DDR2 overall, because of its higher data rate. (explain)

GeForce RTX 2070		458752 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 445952 (3484%)

Texel Rate

The GeForce RTX 2070 will be a lot (approximately 2250%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce RTX 2070		203040 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 194400 (2250%)

Pixel Rate

The GeForce RTX 2070 is quite a bit (about 1989%) more effective at AA than the GeForce 8600 GT 512MB DDR2, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 85920 (1989%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can 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 Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
