GeForce GT 340 vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which comes with core speeds of 1650 MHz on the GPU, and 1937 MHz on the 8192 MB of GDDR6 RAM. It features 3072 SPUs along with 192 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 181 Watts (262%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should be 834% faster than the GeForce GT 340 in general, because of its higher data rate. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 453504 (834%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (about 1700%) better at anisotropic filtering than the GeForce GT 340. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 299200 (1700%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2080 SUPER is the winner, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 101200 (2300%)

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 (counted in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out 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 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 that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
