GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 1660 Ti

Intro

Compare those specifications to the GeForce GTX 1660 Ti, which uses a 12 nm design. nVidia has set the core speed at 1500 MHz. The GDDR6 RAM runs at a frequency of 1500 MHz on this specific model. It features 1536 SPUs as well as 96 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB GDDR3		47 Watts
GeForce GTX 1660 Ti		120 Watts
	Difference: 73 Watts (155%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti will be 1217% faster than the GeForce 8600 GT 1GB GDDR3 in general, due to its greater data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 272512 (1217%)

Texel Rate

The GeForce GTX 1660 Ti is a lot (more or less 1567%) faster with regards to anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 135360 (1567%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1660 Ti is a better choice, and very much so. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 67680 (1567%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
