GeForce RTX 2070 vs Geforce GTX 1080 Ti

Intro

The GeForce RTX 2070 uses a 12 nm design. nVidia has set the core frequency at 1410 MHz. The GDDR6 RAM works at a frequency of 14 MHz on this particular card. It features 2304 SPUs along with 144 TAUs and 64 Rasterization Operator Units.

Compare all that to the Geforce GTX 1080 Ti, which features core speeds of 1480 MHz on the GPU, and 1376 MHz on the 11264 MB of GDDR5X RAM. It features 3584 SPUs as well as 224 Texture Address Units and 88 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better 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 maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
