GeForce GTX 1070 Ti vs Radeon RX 470 4GB

Intro

The GeForce GTX 1070 Ti makes use of a 16 nm design. nVidia has clocked the core speed at 1607 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this particular model. It features 2432 SPUs as well as 152 Texture Address Units and 64 Rasterization Operator Units.

Compare those specifications to the Radeon RX 470 4GB, which comes with GPU clock speed of 926 MHz, and 4096 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels 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 amount of Render Output Units by the the card's clock speed. 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
