GeForce GTX 1660 Ti vs GeForce GTX 650

Intro

Compare all that to the GeForce GTX 650, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this specific card. It features 384 SPUs as well as 32 Texture Address Units and 16 ROPs.

GeForce GTX 650		80000 MB/sec
	Difference: 214912 (269%)

Texel Rate

The GeForce GTX 1660 Ti is a lot (more or less 325%) faster with regards to anisotropic filtering than the GeForce GTX 650. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 110144 (325%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1660 Ti is superior to the GeForce GTX 650, and very much so. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 55072 (325%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
