Geforce GTX 1080 Ti vs Radeon VII

Intro

The Geforce GTX 1080 Ti makes use of a 16 nm design. nVidia has clocked the core frequency at 1480 MHz. The GDDR5X memory runs at a frequency of 1376 MHz on this specific card. It features 3584 SPUs along with 224 Texture Address Units and 88 Rasterization Operator Units.

Compare those specifications to the Radeon VII, which comes with a core clock speed of 1400 MHz and a HBM2 memory speed of 1000 MHz. It also makes use of a 4096-bit memory bus, and makes use of a 7 nm design. It is made up of 3840 SPUs, 240 Texture Address Units, and 64 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be processed in one 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied 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 one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
