GeForce GTX 1650 vs Radeon HD 5450

Intro

Compare those specifications to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 memory works at a frequency of 800 MHz on this specific card. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

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 perform much faster than the Radeon HD 5450 overall. (explain)

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

Texel Rate

The GeForce GTX 1650 is quite a bit (about 1499%) more effective at texture 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 will be a lot (more or less 1728%) better at full screen anti-aliasing than the Radeon HD 5450, and also 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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
