GeForce GTX 1660 Ti vs Radeon R9 290X

Intro

Compare those specifications to the Radeon R9 290X, which has core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2816 SPUs along with 176 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
Radeon R9 290X		300 Watts
	Difference: 180 Watts (150%)

Memory Bandwidth

Performance-wise, the Radeon R9 290X should in theory be a little bit better than the GeForce GTX 1660 Ti in general. (explain)

Radeon R9 290X		320000 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 25088 (9%)

Texel Rate

The GeForce GTX 1660 Ti should be just a bit (approximately 2%) more effective at anisotropic filtering than the Radeon R9 290X. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon R9 290X		140800 Mtexels/sec
	Difference: 3200 (2%)

Pixel Rate

The GeForce GTX 1660 Ti is quite a bit (more or less 41%) better at anti-aliasing than the Radeon R9 290X, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R9 290X		51200 Mpixels/sec
	Difference: 20800 (41%)

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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount 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 handling 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 can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
