GeForce GT 240 GDDR5 vs GeForce RTX 3080

Intro

Compare all that to the GeForce RTX 3080, which uses a 8 nm design. nVidia has set the core speed at 1440 MHz. The GDDR6X memory runs at a speed of 1188 MHz on this specific model. 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 240 GDDR5		70 Watts
GeForce RTX 3080		320 Watts
	Difference: 250 Watts (357%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 should be 1331% quicker than the GeForce GT 240 GDDR5 overall, because of its greater data rate. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 724147 (1331%)

Texel Rate

The GeForce RTX 3080 should be much (more or less 2125%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 374080 (2125%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3080 is superior to the GeForce GT 240 GDDR5, by far. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 133840 (3042%)

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 megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 the video card can 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 colour 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
