GeForce RTX 2080 vs Radeon RX 480 4GB

Intro

The GeForce RTX 2080 has a core clock frequency of 1515 MHz and a GDDR6 memory frequency of 14 MHz. It also makes use of a 256-bit bus, and uses a 12 nm design. It is made up of 2944 SPUs, 184 TAUs, and 64 ROPs.

Compare those specifications to the Radeon RX 480 4GB, which makes use of a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this particular card. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
