GeForce GTX 1650 vs Radeon HD 6790

Intro

Compare those specifications to the Radeon HD 6790, which uses a 40 nm design. AMD has clocked the core frequency at 840 MHz. The GDDR5 memory works at a frequency of 1050 MHz on this particular card. It features 800 SPUs along with 40 TAUs and 16 ROPs.

GeForce GTX 1650		131072 MB/sec
	Difference: 3328 (3%)

Texel Rate

The GeForce GTX 1650 is a lot (more or less 148%) faster with regards to texture filtering than the Radeon HD 6790. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 6790		33600 Mtexels/sec
	Difference: 49560 (148%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1650 is superior to the Radeon HD 6790, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 6790		13440 Mpixels/sec
	Difference: 34080 (254%)

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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 memory bandwidth is, the lower the potential to reach the max fill rate.
