GeForce GTX 660 Ti vs Radeon RX 5700

Intro

Compare that to the Radeon RX 5700, which makes use of a 7 nm design. AMD has set the core frequency at 1465 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this card. It features 2304 SPUs as well as 144 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX 660 Ti		144000 MB/sec
	Difference: 314752 (219%)

Texel Rate

The Radeon RX 5700 should be quite a bit (approximately 106%) better at texture filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 108480 (106%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 is the winner, by far. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 71800 (327%)

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 within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
