GeForce GTX 1650 vs Radeon HD 5450

Intro

Compare those specifications to the Radeon HD 5450, which comes with core clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
GeForce GTX 1650		75 Watts
	Difference: 56 Watts (295%)

Memory Bandwidth

The GeForce GTX 1650 should in theory be a lot faster than the Radeon HD 5450 in general. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 118272 (924%)

Texel Rate

The GeForce GTX 1650 is much (approximately 1499%) faster with regards to anisotropic filtering than the Radeon HD 5450. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 77960 (1499%)

Pixel Rate

The GeForce GTX 1650 is a lot (more or less 1728%) more effective at full screen anti-aliasing than the Radeon HD 5450, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 44920 (1728%)

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 MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
