Radeon R9 280 vs Radeon RX 6700 XT

Intro

Compare those specifications to the Radeon RX 6700 XT, which has core clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 RAM. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Radeon R9 280		240000 MB/sec
	Difference: 153216 (64%)

Texel Rate

The Radeon RX 6700 XT will be a lot (more or less 255%) better at anisotropic filtering than the Radeon R9 280. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 266864 (255%)

Pixel Rate

The Radeon RX 6700 XT should be much (more or less 398%) more effective at FSAA than the Radeon R9 280, and should be capable of handling higher resolutions better. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 280		29856 Mpixels/sec
	Difference: 118688 (398%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
