GeForce GTX 1650 vs GeForce GTX 650

Intro

Compare all of that to the GeForce GTX 650, which has a clock frequency of 1058 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
GeForce GTX 1650		75 Watts
	Difference: 11 Watts (17%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 1650 should in theory be a lot superior to the GeForce GTX 650 in general. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 51072 (64%)

Texel Rate

The GeForce GTX 1650 is quite a bit (more or less 146%) better at anisotropic filtering than the GeForce GTX 650. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 49304 (146%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1650 is superior to the GeForce GTX 650, by far. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 30592 (181%)

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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
