GeForce GTX 1660 Ti vs Radeon HD 5970

Intro

The GeForce GTX 1660 Ti has a GPU clock speed of 1500 MHz, and the 6144 MB of GDDR6 memory runs at 1500 MHz through a 192-bit bus. It also is made up of 1536 Stream Processors, 96 Texture Address Units, and 48 ROPs.

Compare those specs to the Radeon HD 5970, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific model. It features 1600 SPUs as well as 160 Texture Address Units and 64 ROPs.

Radeon HD 5970 256000 MB/sec
Difference: 38912 (15%)

Texel Rate

The Radeon HD 5970 is much (approximately 61%) better at anisotropic filtering than the GeForce GTX 1660 Ti. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 1660 Ti 144000 Mtexels/sec
Difference: 88000 (61%)

Pixel Rate

The Radeon HD 5970 will be much (approximately 29%) better at FSAA than the GeForce GTX 1660 Ti, and also able to handle higher screen resolutions more effectively. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 1660 Ti 72000 Mpixels/sec
Difference: 20800 (29%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core 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 that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
