GeForce GTX 1660 Ti vs Radeon R7 250X

Intro

Compare that to the Radeon R7 250X, which has a clock speed of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Radeon R7 250X		95 Watts
GeForce GTX 1660 Ti		120 Watts
	Difference: 25 Watts (26%)

Memory Bandwidth

Theoretically, the GeForce GTX 1660 Ti should be quite a bit faster than the Radeon R7 250X overall. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 222912 (310%)

Texel Rate

The GeForce GTX 1660 Ti should be a lot (approximately 260%) faster with regards to AF than the Radeon R7 250X. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 104000 (260%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1660 Ti is superior to the Radeon R7 250X, and very much so. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 56000 (350%)

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 transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per 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 the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
