GeForce GTX 1660 Ti vs Radeon R9 270X

Intro

Compare those specs to the Radeon R9 270X, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory is set to run at a speed of 1400 MHz on this card. It features 1280 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Texel Rate

The GeForce GTX 1660 Ti should be a lot (about 80%) more effective at texture filtering than the Radeon R9 270X. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 64000 (80%)

Pixel Rate

The GeForce GTX 1660 Ti will be quite a bit (more or less 125%) more effective at AA than the Radeon R9 270X, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 40000 (125%)

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 (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
