GeForce RTX 2070 Super vs Geforce GTX 690

Intro

Compare that to the Geforce GTX 690, which comes with a core clock speed of 915 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.

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

Memory Bandwidth

The GeForce RTX 2070 Super should in theory be just a bit faster than the Geforce GTX 690 in general. (explain)

Geforce GTX 690		384512 MB/sec
	Difference: 74240 (19%)

Texel Rate

The GeForce RTX 2070 Super should be a bit (about 10%) more effective at texture 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

If using high levels of AA is important to you, then the GeForce RTX 2070 Super is the winner, by far. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, 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 maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
