Radeon R9 270 vs Radeon RX 6950 XT

Intro

Compare all of that to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1925 MHz. The GDDR6 RAM runs at a speed of 2250 MHz on this specific model. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Radeon R9 270		179200 MB/sec
	Difference: 410624 (229%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (approximately 756%) better at AF than the Radeon R9 270. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 544000 (756%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6950 XT is the winner, by far. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 217600 (756%)

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 information (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If 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, 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 is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
