GeForce GTX 1660 Ti vs Radeon R9 280X

Intro

Compare all that to the Radeon R9 280X, which comes with a clock speed of 850 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Radeon R9 280X		108800 Mtexels/sec
	Difference: 35200 (32%)

Pixel Rate

The GeForce GTX 1660 Ti should be a lot (more or less 165%) faster with regards to full screen anti-aliasing than the Radeon R9 280X, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 44800 (165%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
