GeForce GTS 450 1GB vs GeForce GTX 1650

Intro

Compare those specs to the GeForce GTX 1650, which makes use of a 12 nm design. nVidia has clocked the core frequency at 1485 MHz. The GDDR5 RAM runs at a frequency of 2001 MHz on this card. It features 896 SPUs along with 56 Texture Address Units and 32 ROPs.

GeForce GTX 1650		75 Watts
GeForce GTS 450 1GB		106 Watts
	Difference: 31 Watts (41%)

Memory Bandwidth

In theory, the GeForce GTX 1650 should be a lot faster than the GeForce GTS 450 1GB overall. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GTS 450 1GB		57728 MB/sec
	Difference: 73344 (127%)

Texel Rate

The GeForce GTX 1650 should be quite a bit (more or less 232%) more effective at AF than the GeForce GTS 450 1GB. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 58104 (232%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1650 is a better choice, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 34992 (279%)

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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
