Geforce GTX 1080 Ti vs Radeon RX 5700

Intro

The Geforce GTX 1080 Ti has a clock speed of 1480 MHz and a GDDR5X memory speed of 1376 MHz. It also makes use of a 352-bit bus, and makes use of a 16 nm design. It features 3584 SPUs, 224 TAUs, and 88 Raster Operation Units.

Compare those specifications to the Radeon RX 5700, which makes use of a 7 nm design. AMD has set the core speed at 1465 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
