GeForce GTX 1070 Ti vs Radeon HD 7970

Intro

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

Compare all of that to the Radeon HD 7970, which has GPU core speed of 925 MHz, and 3072 MB of GDDR5 memory set to run at 1375 MHz through a 384-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
