GeForce GTX 1660 Ti vs Radeon HD 5970

Intro

The GeForce GTX 1660 Ti features a clock frequency of 1500 MHz and a GDDR6 memory speed of 12000 MHz. It also makes use of a 192-bit bus, and uses a 12 nm design. It features 1536 SPUs, 96 Texture Address Units, and 48 ROPs.

Compare those specs to the Radeon HD 5970, which features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1600 SPUs along with 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti 120 Watts
Radeon HD 5970 294 Watts
Difference: 174 Watts (145%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti will be 15% quicker than the Radeon HD 5970 overall, because of its greater data rate. (explain)

GeForce GTX 1660 Ti 294912 MB/sec
Radeon HD 5970 256000 MB/sec
Difference: 38912 (15%)

Texel Rate

The Radeon HD 5970 is much (more or less 61%) more effective at AF 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

If running with lots of anti-aliasing is important to you, then the Radeon HD 5970 is the winner, by a large margin. (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 maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
