GeForce GTX 1630 vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1630 makes use of a 12 nm design. nVidia has set the core speed at 1740 MHz. The GDDR6 memory runs at a speed of 1500 MHz on this card. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare that to the GeForce GTX 1660 Ti, which comes with a clock speed of 1500 MHz and a GDDR6 memory frequency of 1500 MHz. It also features a 192-bit memory bus, and makes use of a 12 nm design. It is comprised of 1536 SPUs, 96 Texture Address Units, and 48 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
