GeForce GTX 1650 vs Radeon HD 6850

Intro

Compare those specifications to the Radeon HD 6850, which features clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 960 SPUs along with 48 TAUs and 32 ROPs.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1650 should be a little bit faster than the Radeon HD 6850 in general. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 6850		128000 MB/sec
	Difference: 3072 (2%)

Texel Rate

The GeForce GTX 1650 is quite a bit (about 124%) better at AF than the Radeon HD 6850. (explain)

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

Pixel Rate

If using a high 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 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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
