GeForce RTX 3090 vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this particular model. It features 1344 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 670		170 Watts
GeForce RTX 3090		350 Watts
	Difference: 180 Watts (106%)

Memory Bandwidth

The GeForce RTX 3090, in theory, should perform much faster than the Geforce GTX 670 in general. (explain)

GeForce RTX 3090		958668 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 766668 (399%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (about 346%) better at anisotropic filtering than the Geforce GTX 670. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 355080 (346%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3090 is the winner, by far. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 126960 (434%)

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 information (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 maximum fill rate.
