Radeon HD 6670 (OEM) 1GB vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has clocked the core speed at 2200 MHz. The GDDR6 RAM works at a speed of 2250 MHz on this model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (about 1000%) better at anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and also should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 6670 (OEM) 1GB		6400 Mpixels/sec
	Difference: 64000 (1000%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
