GeForce GTX 1660 Ti vs GeForce GTX 650

Intro

The GeForce GTX 1660 Ti features a clock frequency of 1500 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of 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.

Compare all of that to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core frequency at 1058 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this model. It features 384 SPUs along with 32 TAUs and 16 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
