GeForce GT 1030 vs GeForce RTX 2080

Intro

Compare all of that to the GeForce RTX 2080, which has a core clock speed of 1515 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit memory bus, and makes use of a 12 nm design. It is made up of 2944 SPUs, 184 Texture Address Units, and 64 Raster Operation Units.

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

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 should in theory be a lot better than the GeForce GT 1030 in general. (explain)

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

Texel Rate

The GeForce RTX 2080 will be quite a bit (about 589%) more effective 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

The GeForce RTX 2080 is much (more or less 379%) more effective at anti-aliasing than the GeForce GT 1030, and should be able to handle higher resolutions better. (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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
