Radeon HD 6450 (OEM) vs Radeon RX 5500 XT
Intro
The Radeon HD 6450 (OEM) uses a 40 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 memory works at a speed of 800 MHz on this particular model. It features 160 SPUs along with 8 Texture Address Units and 4 ROPs.Compare those specifications to the Radeon RX 5500 XT, which comes with a GPU core clock speed of 1717 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also features 1408 Stream Processors, 88 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
