GeForce RTX 2060 vs Radeon HD 5450

Intro

The GeForce RTX 2060 makes use of a 12 nm design. nVidia has clocked the core frequency at 1365 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this specific card. It features 1920 SPUs as well as 120 Texture Address Units and 48 Rasterization Operator Units.

Compare those specifications to the Radeon HD 5450, which features a clock speed of 650 MHz and a DDR3 memory frequency of 800 MHz. It also features a 64-bit bus, and uses a 40 nm design. It is comprised of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
