Dimensions and Compatibility

A comparison of video cards NVIDIA GeForce 800A vs ATI Radeon HD 3850 AGP in terms of length, connection interface, as well as the number of required pins for power on the motherboard (power supply). 
If you are considering a new graphics card to upgrade your system, you should consider the following:
1) Measure the length of your existing graphics card; if it is shorter, you will have to buy an extra larger system case. This will be useful not only for the video card to fit there, but also for more efficient cooling of the system.
2) The number of power phases on the motherboard and power supply compatibility. High performance graphics cards require higher wattage power supplies and some of them need more pins to be connected to the motherboard. So make sure that your motherboard supports the video card.
This is all you need to know when analyzing a comparison between graphics cards NVIDIA GeForce 800A and ATI Radeon HD 3850 AGP in connection interface and main dimensions.

Graphics memory (technical specifications)

Video memory comparison NVIDIA GeForce 800A vs ATI Radeon HD 3850 AGP A very important model comparison unit, here you will understand which video card deserves your attention and which you can safely forget. In today's reality, new working applications, even games, are becoming more demanding on the hardware resources of the computer, where video memory is one of the important ones. The more memory of the video card, the faster the data is processed and less lag is observed when watching video, gaming, rendering. 
Which video card to choose by memory between NVIDIA GeForce 800A and {{video_card_name_2}?
1) Look at the GDDR type. The higher it is, the more modern and performant the model is.
2) How much memory is installed? The more memory, the faster multiple data sets will be handled.
3) Bandwidth. The higher the figure, the better.
4) Memory bus width. Similar to the fourth point.

As you can see, determining the winner of this comparison is not that difficult. You just need to compare the characteristics and decide in favor of the model with the best performance.
