Radeon HD 6450 (OEM) vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has clocked the core speed at 1968 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 249344 (1948%)

Texel Rate

The Radeon RX 6600 XT is quite a bit (about 4938%) faster with regards to AF than the Radeon HD 6450 (OEM). (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 246904 (4938%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is superior to the Radeon HD 6450 (OEM), by a large margin. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 123452 (4938%)

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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its 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 card's 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
