GeForce RTX 2060 vs Radeon R9 270

Intro

Compare all of that to the Radeon R9 270, which features core speeds of 900 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 RAM. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Radeon R9 270		179200 MB/sec
	Difference: 164864 (92%)

Texel Rate

The GeForce RTX 2060 should be much (more or less 128%) faster with regards to anisotropic filtering than the Radeon R9 270. (explain)

GeForce RTX 2060		163800 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 91800 (128%)

Pixel Rate

The GeForce RTX 2060 should be quite a bit (about 128%) more effective at full screen anti-aliasing than the Radeon R9 270, and able to handle higher screen resolutions better. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 36720 (128%)

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 data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card 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 most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
