GeForce GTX 1660 Ti vs Radeon R9 295X2

Intro

The GeForce GTX 1660 Ti features a clock speed of 1500 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit bus, and makes use of a 12 nm design. It is made up of 1536 SPUs, 96 Texture Address Units, and 48 Raster Operation Units.

Compare those specs to the Radeon R9 295X2, which uses a 28 nm design. AMD has clocked the core frequency at 1018 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this model. It features 2816 SPUs as well as 176 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX 1660 Ti 144000 Mtexels/sec
Difference: 214336 (149%)

Pixel Rate

The Radeon R9 295X2 will be quite a bit (about 81%) faster with regards to full screen anti-aliasing than the GeForce GTX 1660 Ti, and also will be capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
