GeForce GTX 1660 Ti vs Radeon R9 295X2

Intro

The GeForce GTX 1660 Ti comes with a GPU core clock speed of 1500 MHz, and the 6144 MB of GDDR6 RAM runs at 1500 MHz through a 192-bit bus. It also features 1536 SPUs, 96 Texture Address Units, and 48 Raster Operation Units.

Compare those specifications to the Radeon R9 295X2, which has a clock frequency of 1018 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 512-bit memory bus, and uses a 28 nm design. It is made up of 2816 SPUs, 176 Texture Address Units, and 64 ROPs.

Difference: 345088 (117%)

Texel Rate

The Radeon R9 295X2 should be a lot (more or less 149%) faster with regards to texture filtering 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 is a lot (more or less 81%) more effective at AA than the GeForce GTX 1660 Ti, and capable of handling higher resolutions more effectively. (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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once 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 AA, High Dynamic Range and high resolutions.

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

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