GeForce GTX 1070 Ti vs Radeon RX Vega 64

Intro

The GeForce GTX 1070 Ti features a GPU clock speed of 1607 MHz, and the 8192 MB of GDDR5 RAM is set to run at 2000 MHz through a 256-bit bus. It also is made up of 2432 SPUs, 152 TAUs, and 64 ROPs.

Compare all that to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has set the core speed at 1247 MHz. The HBM2 memory runs at a speed of 1890 MHz on this card. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
