Radeon R9 285 vs Radeon RX 6700 XT

Intro

Compare those specs to the Radeon RX 6700 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 2321 MHz. The GDDR6 memory works at a speed of 2000 MHz on this specific model. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Radeon R9 285		176000 MB/sec
	Difference: 217216 (123%)

Texel Rate

The Radeon RX 6700 XT is quite a bit (about 261%) more effective at AF than the Radeon R9 285. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 285		102816 Mtexels/sec
	Difference: 268544 (261%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6700 XT is the winner, by far. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 285		29376 Mpixels/sec
	Difference: 119168 (406%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 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 number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
