GeForce GTX 1650 vs Radeon HD 6770

Intro

Compare all of that to the Radeon HD 6770, which makes use of a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 RAM works at a frequency of 1050 MHz on this particular card. It features 800 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon HD 6770		108 Watts
	Difference: 33 Watts (44%)

Memory Bandwidth

In theory, the GeForce GTX 1650 should be a lot faster than the Radeon HD 6770 in general. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 6770		67200 MB/sec
	Difference: 63872 (95%)

Texel Rate

The GeForce GTX 1650 should be quite a bit (about 131%) more effective at AF than the Radeon HD 6770. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 6770		36000 Mtexels/sec
	Difference: 47160 (131%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1650 is the winner, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 6770		14400 Mpixels/sec
	Difference: 33120 (230%)

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 data (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
