GeForce RTX 3070 vs GeForce RTX 3090

Intro

The GeForce RTX 3070 features clock speeds of 1500 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 5888 SPUs along with 184 Texture Address Units and 96 Rasterization Operator Units.

Compare those specs to the GeForce RTX 3090, which uses a 8 nm design. nVidia has clocked the core speed at 1395 MHz. The GDDR6X memory runs at a speed of 1219 MHz on this card. It features 10496 SPUs along with 328 Texture Address Units and 112 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
