GeForce GTX 1650 vs Radeon HD 7850

Intro

Compare all that to the Radeon HD 7850, which has a GPU core clock speed of 860 MHz, and 2048 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 32 ROPs.

GeForce GTX 1650		75 Watts
Radeon HD 7850		130 Watts
	Difference: 55 Watts (73%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7850 should perform a small bit faster than the GeForce GTX 1650 in general. (explain)

Radeon HD 7850		153600 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 22528 (17%)

Texel Rate

The GeForce GTX 1650 should be much (about 51%) better at texture filtering than the Radeon HD 7850. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 7850		55040 Mtexels/sec
	Difference: 28120 (51%)

Pixel Rate

The GeForce GTX 1650 should be quite a bit (more or less 73%) faster with regards to AA than the Radeon HD 7850, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 7850		27520 Mpixels/sec
	Difference: 20000 (73%)

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 MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
