GeForce RTX 2070 Super vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which has GPU clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 256-bit bus. It also features 1344 SPUs, 112 TAUs, and 32 ROPs.

Geforce GTX 670		192000 MB/sec
	Difference: 266752 (139%)

Texel Rate

The GeForce RTX 2070 Super will be much (about 151%) better at texture filtering than the Geforce GTX 670. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 154320 (151%)

Pixel Rate

The GeForce RTX 2070 Super should be much (more or less 251%) more effective at anti-aliasing than the Geforce GTX 670, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 73440 (251%)

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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
