GeForce GTX 1660 Ti vs Radeon RX 590

Intro

The GeForce GTX 1660 Ti uses a 12 nm design. nVidia has set the core frequency at 1500 MHz. The GDDR6 memory works at a frequency of 12000 MHz on this specific card. It features 1536 SPUs along with 96 TAUs and 48 Rasterization Operator Units.

Compare all of that to the Radeon RX 590, which features clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
