GeForce RTX 3070 vs GeForce RTX 3090

Intro

The GeForce RTX 3070 comes with a GPU core speed of 1500 MHz, and the 8192 MB of GDDR6 memory runs at 1750 MHz through a 256-bit bus. It also features 5888 SPUs, 184 Texture Address Units, and 96 ROPs.

Compare all of that to the GeForce RTX 3090, which has GPU clock speed of 1395 MHz, and 24576 MB of GDDR6X memory running at 1219 MHz through a 384-bit bus. It also is comprised of 10496 Stream Processors, 328 Texture Address Units, and 112 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070 220 Watts
GeForce RTX 3090 350 Watts
Difference: 130 Watts (59%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3090 will be -100% faster than the GeForce RTX 3070 in general, because of its higher bandwidth. (explain)

GeForce RTX 3090 958668 MB/sec
GeForce RTX 3070 (Unknown) MB/sec
Difference: 958668 (-100%)

Texel Rate

The GeForce RTX 3090 should be much (about 66%) faster with regards to texture filtering than the GeForce RTX 3070. (explain)

GeForce RTX 3090 457560 Mtexels/sec
GeForce RTX 3070 276000 Mtexels/sec
Difference: 181560 (66%)

Pixel Rate

If using a high resolution is important to you, then the GeForce RTX 3090 is superior to the GeForce RTX 3070, though only just barely. (explain)

GeForce RTX 3090 156240 Mpixels/sec
GeForce RTX 3070 144000 Mpixels/sec
Difference: 12240 (9%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
