Radeon HD 6670 (OEM) 1GB vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has set the core speed at 1968 MHz. The GDDR6 RAM is set to run at a speed of 2000 MHz on this specific model. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

Radeon RX 6600 XT		160 Watts
	Difference: 97 Watts (154%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 XT should be 310% faster than the Radeon HD 6670 (OEM) 1GB in general, because of its higher bandwidth. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon HD 6670 (OEM) 1GB		64000 MB/sec
	Difference: 198144 (310%)

Texel Rate

The Radeon RX 6600 XT should be much (approximately 1212%) more effective at AF than the Radeon HD 6670 (OEM) 1GB. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon HD 6670 (OEM) 1GB		19200 Mtexels/sec
	Difference: 232704 (1212%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is a better choice, by a large margin. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon HD 6670 (OEM) 1GB		6400 Mpixels/sec
	Difference: 119552 (1868%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
