GeForce GTX 1650 vs Radeon HD 6850

Intro

Compare all of that to the Radeon HD 6850, which has core clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 960 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 6850		128000 MB/sec
	Difference: 3072 (2%)

Texel Rate

The GeForce GTX 1650 is a lot (more or less 124%) faster with regards to texture filtering than the Radeon HD 6850. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 6850		37200 Mtexels/sec
	Difference: 45960 (124%)

Pixel Rate

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

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 6850		24800 Mpixels/sec
	Difference: 22720 (92%)

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 (counted in MB per second) that can be transported over the external memory interface within a 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 ANOTHER 2x. The better the bandwidth is, 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 worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 ability to reach the max fill rate.
