GeForce GTX 1660 Ti vs Radeon R9 270

Intro

The GeForce GTX 1660 Ti uses a 12 nm design. nVidia has set the core frequency at 1500 MHz. The GDDR6 RAM is set to run at a frequency of 12000 MHz on this particular card. It features 1536 SPUs as well as 96 Texture Address Units and 48 ROPs.

Compare all that to the Radeon R9 270, which uses a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 RAM works at a speed of 1400 MHz on this card. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti 120 Watts
Radeon R9 270 150 Watts
Difference: 30 Watts (25%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti will be 65% quicker than the Radeon R9 270 in general, due to its higher bandwidth. (explain)

GeForce GTX 1660 Ti 294912 MB/sec
Radeon R9 270 179200 MB/sec
Difference: 115712 (65%)

Texel Rate

The GeForce GTX 1660 Ti is quite a bit (about 100%) faster with regards to texture filtering than the Radeon R9 270. (explain)

GeForce GTX 1660 Ti 144000 Mtexels/sec
Radeon R9 270 72000 Mtexels/sec
Difference: 72000 (100%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1660 Ti is a better choice, and very much so. (explain)

GeForce GTX 1660 Ti 72000 Mpixels/sec
Radeon R9 270 28800 Mpixels/sec
Difference: 43200 (150%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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.
