GeForce GTX 1660 Ti vs Radeon HD 6990

Intro

The GeForce GTX 1660 Ti has core speeds of 1500 MHz on the GPU, and 12000 MHz on the 6144 MB of GDDR6 memory. It features 1536 SPUs along with 96 TAUs and 48 Rasterization Operator Units.

Compare all that to the Radeon HD 6990, which uses a 40 nm design. AMD has set the core frequency at 830 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this particular model. It features 1536 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1660 Ti is the winner, by a large margin. (explain)

GeForce GTX 1660 Ti 72000 Mpixels/sec
Radeon HD 6990 53120 Mpixels/sec
Difference: 18880 (36%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 speed of the chip. The better this number, the better the 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 video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
