GeForce GTX 1660 Ti vs Radeon R9 290

Intro

Compare all that to the Radeon R9 290, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this particular card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 25088 (9%)

Texel Rate

The GeForce GTX 1660 Ti is a small bit (approximately 13%) faster with regards to texture filtering than the Radeon R9 290. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon R9 290		128000 Mtexels/sec
	Difference: 16000 (13%)

Pixel Rate

The GeForce GTX 1660 Ti should be quite a bit (more or less 41%) more effective at AA than the Radeon R9 290, and should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon R9 290		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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling 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 video card could 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 ROPs by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
