GeForce RTX 3050 vs Geforce GTX 680

Intro

Compare those specifications to the Geforce GTX 680, which has a GPU core clock speed of 1006 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 TAUs, and 32 ROPs.

GeForce RTX 3050		130 Watts
Geforce GTX 680		195 Watts
	Difference: 65 Watts (50%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3050 will be 19% faster than the Geforce GTX 680 in general, because of its greater bandwidth. (explain)

GeForce RTX 3050		229376 MB/sec
Geforce GTX 680		192256 MB/sec
	Difference: 37120 (19%)

Texel Rate

The Geforce GTX 680 will be a bit (approximately 4%) better at anisotropic filtering than the GeForce RTX 3050. (explain)

Geforce GTX 680		128768 Mtexels/sec
GeForce RTX 3050		124160 Mtexels/sec
	Difference: 4608 (4%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3050 is superior to the Geforce GTX 680, by a large margin. (explain)

GeForce RTX 3050		49664 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 17472 (54%)

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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
