GeForce 8400 GS 512MB vs GeForce RTX 3060

Intro

Compare those specs to the GeForce RTX 3060, which comes with core speeds of 1320 MHz on the GPU, and 1875 MHz on the (Unknown) MB of GDDR6 memory. It features 3584 SPUs along with 112 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8400 GS 512MB		40 Watts
GeForce RTX 3060		170 Watts
	Difference: 130 Watts (325%)

Memory Bandwidth

Performance-wise, the GeForce RTX 3060 should in theory be a lot superior to the GeForce 8400 GS 512MB overall. (explain)

GeForce RTX 3060		368640 MB/sec
GeForce 8400 GS 512MB		6400 MB/sec
	Difference: 362240 (5660%)

Texel Rate

The GeForce RTX 3060 will be quite a bit (more or less 2743%) better at AF than the GeForce 8400 GS 512MB. (explain)

GeForce RTX 3060		147840 Mtexels/sec
GeForce 8400 GS 512MB		5200 Mtexels/sec
	Difference: 142640 (2743%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3060 is the winner, and very much so. (explain)

GeForce RTX 3060		63360 Mpixels/sec
GeForce 8400 GS 512MB		2600 Mpixels/sec
	Difference: 60760 (2337%)

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 max amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
