GeForce GTX 470 vs GeForce RTX 2080 SUPER

Intro

The GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 RAM is set to run at a frequency of 837 MHz on this specific model. It features 448 SPUs along with 56 Texture Address Units and 40 Rasterization Operator Units.

Compare those specs to the GeForce RTX 2080 SUPER, which makes use of a 12 nm design. nVidia has set the core speed at 1650 MHz. The GDDR6 RAM works at a speed of 1937 MHz on this particular card. It features 3072 SPUs as well as 192 TAUs and 64 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
