Radeon HD 6450 (OEM) vs Radeon RX 5600 XT
Intro
The Radeon HD 6450 (OEM) features a GPU core clock speed of 625 MHz, and the 512 MB of GDDR3 RAM runs at 800 MHz through a 64-bit bus. It also is made up of 160 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.Compare all of that to the Radeon RX 5600 XT, which comes with a core clock frequency of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit bus, and makes use of a 7 nm design. It features 2304 SPUs, 144 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
