GeForce RTX 2080 Ti vs Radeon R9 280

Intro

The GeForce RTX 2080 Ti uses a 12 nm design. nVidia has clocked the core frequency at 1350 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this specific model. It features 4352 SPUs as well as 272 Texture Address Units and 88 Rasterization Operator Units.

Compare those specs to the Radeon R9 280, which comes with a clock frequency of 933 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
