GeForce GTX 1660 Ti vs Radeon HD 7950

Intro

Compare all of that to the Radeon HD 7950, which makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this model. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Radeon HD 7950		89600 Mtexels/sec
	Difference: 54400 (61%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1660 Ti is superior to the Radeon HD 7950, by a large margin. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 46400 (181%)

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 data (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
