GeForce GTX 1650 vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which uses a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this particular card. It features 1344 SPUs as well as 112 Texture Address Units and 32 ROPs.

GeForce GTX 1650		83160 Mtexels/sec
	Difference: 19320 (23%)

Pixel Rate

The GeForce GTX 1650 will be quite a bit (about 62%) more effective at full screen anti-aliasing than the Geforce GTX 670, and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 18240 (62%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
