GeForce RTX 3060 vs Geforce GTX 690

Intro

Compare that to the Geforce GTX 690, which features a core clock speed of 915 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3060		170 Watts
Geforce GTX 690		300 Watts
	Difference: 130 Watts (76%)

Memory Bandwidth

In theory, the Geforce GTX 690 is 4% quicker than the GeForce RTX 3060 overall, due to its greater bandwidth. (explain)

Geforce GTX 690		384512 MB/sec
GeForce RTX 3060		368640 MB/sec
	Difference: 15872 (4%)

Texel Rate

The Geforce GTX 690 is much (approximately 58%) better at anisotropic filtering than the GeForce RTX 3060. (explain)

Geforce GTX 690		234240 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 86400 (58%)

Pixel Rate

The GeForce RTX 3060 should be a little bit (approximately 8%) better at anti-aliasing than the Geforce GTX 690, and also should be able to handle higher screen resolutions better. (explain)

GeForce RTX 3060		63360 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 4800 (8%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, 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 texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
