GeForce GTX 1660 Ti vs Radeon R9 280

Intro

Compare those specifications to the Radeon R9 280, which uses a 28 nm design. AMD has clocked the core frequency at 933 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this model. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.

Radeon R9 280		240000 MB/sec
	Difference: 54912 (23%)

Texel Rate

The GeForce GTX 1660 Ti will be quite a bit (approximately 38%) more effective at anisotropic filtering than the Radeon R9 280. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 39504 (38%)

Pixel Rate

The GeForce GTX 1660 Ti should be much (approximately 141%) better at full screen anti-aliasing than the Radeon R9 280, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R9 280		29856 Mpixels/sec
	Difference: 42144 (141%)

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 MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
