GeForce RTX 2070 Super vs Geforce GTX 690

Intro

Compare those specs to the Geforce GTX 690, which features GPU clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070 Super		215 Watts
Geforce GTX 690		300 Watts
	Difference: 85 Watts (40%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2070 Super will be 19% quicker than the Geforce GTX 690 overall, because of its higher bandwidth. (explain)

GeForce RTX 2070 Super		458752 MB/sec
Geforce GTX 690		384512 MB/sec
	Difference: 74240 (19%)

Texel Rate

The GeForce RTX 2070 Super will be a little bit (more or less 10%) better at anisotropic filtering than the Geforce GTX 690. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Geforce GTX 690		234240 Mtexels/sec
	Difference: 22560 (10%)

Pixel Rate

The GeForce RTX 2070 Super should be a lot (about 75%) more effective at full screen anti-aliasing than the Geforce GTX 690, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 44160 (75%)

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: Bandwidth is the largest amount of data (counted in MB 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 the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
