GeForce GT 220 GDDR3 vs GeForce RTX 3080

Intro

Compare all of that to the GeForce RTX 3080, which uses a 8 nm design. nVidia has set the core frequency at 1440 MHz. The GDDR6X memory runs at a speed of 1188 MHz on this card. It features 8704 SPUs as well as 272 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
GeForce RTX 3080		320 Watts
	Difference: 262 Watts (452%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 is 2304% quicker than the GeForce GT 220 GDDR3 in general, due to its higher bandwidth. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 746163 (2304%)

Texel Rate

The GeForce RTX 3080 is much (approximately 3817%) better at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 381680 (3817%)

Pixel Rate

The GeForce RTX 3080 is quite a bit (more or less 2665%) more effective at FSAA than the GeForce GT 220 GDDR3, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 133240 (2665%)

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 megabytes per second) that can be transported across the external memory interface in a second. It's calculated 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 it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
