GeForce RTX 2060 vs Geforce GTX 780

Intro

The GeForce RTX 2060 features a clock speed of 1365 MHz and a GDDR6 memory frequency of 14000 MHz. It also makes use of a 192-bit bus, and makes use of a 12 nm design. It is comprised of 1920 SPUs, 120 TAUs, and 48 ROPs.

Compare those specifications to the Geforce GTX 780, which uses a 28 nm design. nVidia has set the core speed at 863 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this model. It features 2304 SPUs along with 192 Texture Address Units and 48 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If 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, High Dynamic Range 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 texture units by the core clock speed of the chip. The higher this number, the better the 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 that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
