Radeon HD 6450 (OEM) vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which has core speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 282112 (2204%)

Texel Rate

The Radeon RX 5600 should be much (approximately 3420%) better at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 171000 (3420%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5600 is a better choice, and very much so. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 85500 (3420%)

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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's 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 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
