Radeon R9 270X vs Radeon RX 6700 XT

Intro

Compare all that to the Radeon RX 6700 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 2321 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this particular card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

	Difference: 214016 (119%)

Texel Rate

The Radeon RX 6700 XT will be much (more or less 364%) better at texture filtering than the Radeon R9 270X. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 291360 (364%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6700 XT is a better choice, by a large margin. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 116544 (364%)

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: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
