GeForce GTX 1650 vs Radeon HD 6870

Intro

Compare all of that to the Radeon HD 6870, which has clock speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 1120 SPUs as well as 56 Texture Address Units and 32 ROPs.

Radeon HD 6870		151 Watts
	Difference: 76 Watts (101%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6870 is 3% quicker than the GeForce GTX 1650 in general, due to its greater data rate. (explain)

Radeon HD 6870		134400 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 3328 (3%)

Texel Rate

The GeForce GTX 1650 should be much (approximately 65%) more effective at anisotropic filtering than the Radeon HD 6870. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 6870		50400 Mtexels/sec
	Difference: 32760 (65%)

Pixel Rate

The GeForce GTX 1650 is quite a bit (about 65%) more effective at full screen anti-aliasing than the Radeon HD 6870, and able to handle higher resolutions better. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 6870		28800 Mpixels/sec
	Difference: 18720 (65%)

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 data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
