GeForce GTX 1660 Ti vs Radeon R9 295X2

Intro

The GeForce GTX 1660 Ti makes use of a 12 nm design. nVidia has set the core speed at 1500 MHz. The GDDR6 RAM runs at a frequency of 12000 MHz on this particular model. It features 1536 SPUs along with 96 TAUs and 48 Rasterization Operator Units.

Compare those specifications to the Radeon R9 295X2, which comes with clock speeds of 1018 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2816 SPUs along with 176 TAUs and 64 Rasterization Operator Units.

Texel Rate

The Radeon R9 295X2 is a lot (approximately 149%) faster with regards to AF than the GeForce GTX 1660 Ti. (explain)

Radeon R9 295X2 358336 Mtexels/sec
GeForce GTX 1660 Ti 144000 Mtexels/sec
Difference: 214336 (149%)

Pixel Rate

The Radeon R9 295X2 should be quite a bit (more or less 81%) better at FSAA than the GeForce GTX 1660 Ti, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 295X2 130304 Mpixels/sec
GeForce GTX 1660 Ti 72000 Mpixels/sec
Difference: 58304 (81%)

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 data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could 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 Raster Operations Pipelines by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
