GeForce GTX 1050 3GB vs GeForce GTX 650 Ti

Intro

Compare those specifications to the GeForce GTX 650 Ti, which comes with a core clock frequency of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 768 SPUs, 64 Texture Address Units, and 16 ROPs.

As far as performance goes, the GeForce GTX 650 Ti should in theory be a small bit superior to the GeForce GTX 1050 3GB overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 384 (0%)

Texel Rate

The GeForce GTX 1050 3GB will be a bit (about 13%) more effective at texture filtering than the GeForce GTX 650 Ti. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 7424 (13%)

Pixel Rate

The GeForce GTX 1050 3GB is quite a bit (more or less 125%) better at full screen anti-aliasing than the GeForce GTX 650 Ti, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 18560 (125%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the 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 number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
