GeForce GTX 1070 Ti vs Radeon RX Vega 56

Intro

The GeForce GTX 1070 Ti uses a 16 nm design. nVidia has set the core speed at 1607 MHz. The GDDR5 RAM works at a frequency of 2000 MHz on this specific model. It features 2432 SPUs as well as 152 Texture Address Units and 64 ROPs.

Compare all of that to the Radeon RX Vega 56, which comes with GPU clock speed of 1156 MHz, and 8192 MB of HBM2 memory set to run at 1600 MHz through a 2048-bit bus. It also features 3584 Stream Processors, 224 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 number is worked out by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
