GeForce GTX 1650 vs GeForce GTX 275

Intro

Compare all of that to the GeForce GTX 275, which makes use of a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 RAM runs at a frequency of 1134 MHz on this model. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

GeForce GTX 275		127008 MB/sec
	Difference: 4064 (3%)

Texel Rate

The GeForce GTX 1650 should be much (more or less 64%) faster with regards to texture filtering than the GeForce GTX 275. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 32520 (64%)

Pixel Rate

The GeForce GTX 1650 should be quite a bit (approximately 168%) better at AA than the GeForce GTX 275, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 29796 (168%)

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 max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
