GeForce GTX 650 Ti 2GB vs GeForce RTX 2070

Intro

Compare that to the GeForce RTX 2070, which features a core clock frequency of 1410 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 12 nm design. It features 2304 SPUs, 144 Texture Address Units, and 64 ROPs.

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 143648 (242%)

Pixel Rate

If using a high resolution is important to you, then the GeForce RTX 2070 is superior to the GeForce GTX 650 Ti 2GB, and very much so. (explain)

GeForce RTX 2070		90240 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 75392 (508%)

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 maximum amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one 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 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
