Radeon HD 6450 (OEM) vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which has GPU core speed of 1670 MHz, and 4096 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1408 Stream Processors, 88 Texture Address Units, and 32 ROPs.

Radeon RX 5500		229376 MB/sec
Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 216576 (1692%)

Texel Rate

The Radeon RX 5500 should be quite a bit (about 2839%) faster with regards to texture filtering than the Radeon HD 6450 (OEM). (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 141960 (2839%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 is the winner, and very much so. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 50940 (2038%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
