GeForce GT 1030 vs GeForce RTX 2080

Intro

Compare those specifications to the GeForce RTX 2080, which comes with GPU core speed of 1515 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2944 Stream Processors, 184 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce RTX 2080		215 Watts
	Difference: 185 Watts (617%)

Memory Bandwidth

The GeForce RTX 2080 should in theory be quite a bit faster than the GeForce GT 1030 overall. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 409600 (833%)

Texel Rate

The GeForce RTX 2080 should be much (more or less 589%) better at AF than the GeForce GT 1030. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 238280 (589%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2080 is the winner, by far. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 76720 (379%)

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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video 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 its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
