GeForce RTX 3090 vs Radeon VII

Intro

The GeForce RTX 3090 features a GPU core clock speed of 1395 MHz, and the 24576 MB of GDDR6X memory runs at 1219 MHz through a 384-bit bus. It also is comprised of 10496 Stream Processors, 328 TAUs, and 112 ROPs.

Compare those specifications to the Radeon VII, which has a core clock speed of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also features a 4096-bit bus, and uses a 7 nm design. It features 3840 SPUs, 240 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
