Radeon HD 6970 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which features a clock frequency of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also features a 64-bit memory bus, and uses a 6 nm design. It features 1024 SPUs, 64 TAUs, and 32 ROPs.

Texel Rate

The Radeon RX 6500 XT is a lot (approximately 67%) more effective at texture filtering than the Radeon HD 6970. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon HD 6970		84480 Mtexels/sec
	Difference: 56320 (67%)

Pixel Rate

The Radeon RX 6500 XT should be a lot (about 150%) better at FSAA than the Radeon HD 6970, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 6970		28160 Mpixels/sec
	Difference: 42240 (150%)

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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
