GeForce RTX 3070 vs GeForce RTX 3090

Intro

The GeForce RTX 3070 features a GPU core speed of 1500 MHz, and the 8192 MB of GDDR6 RAM is set to run at 1750 MHz through a 256-bit bus. It also features 5888 SPUs, 184 TAUs, and 96 ROPs.

Compare those specs to the GeForce RTX 3090, which features clock speeds of 1395 MHz on the GPU, and 1219 MHz on the 24576 MB of GDDR6X memory. It features 10496 SPUs as well as 328 Texture Address Units and 112 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
