Radeon R9 280X vs Radeon RX 6700 XT

Intro

Compare that to the Radeon RX 6700 XT, which comes with GPU core speed of 2321 MHz, and (Unknown) MB of GDDR6 memory set to run at 2000 MHz through a 192-bit bus. It also is made up of 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Radeon RX 6700 XT		230 Watts
Radeon R9 280X		250 Watts
	Difference: 20 Watts (9%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT should be 37% faster than the Radeon R9 280X overall, due to its greater data rate. (explain)

Radeon RX 6700 XT		393216 MB/sec
Radeon R9 280X		288000 MB/sec
	Difference: 105216 (37%)

Texel Rate

The Radeon RX 6700 XT will be quite a bit (about 241%) more effective at texture filtering than the Radeon R9 280X. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 262560 (241%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6700 XT is superior to the Radeon R9 280X, by a large margin. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 121344 (446%)

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 data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the potential to reach the max fill rate.
