4) The manufacturing process (lithography), indicated in nanometers, the smaller the value, the more advanced the graphics card.
Do not forget to study the comparison of video card test results in benchmarks, it will complement the overall picture of the analysis when reviewing the advantages and disadvantages.

Dimensions and Compatibility

A comparison of video cards NVIDIA GeForce GT 645M vs AMD Radeon R6 (Carrizo) 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 GT 645M and AMD Radeon R6 (Carrizo) in connection interface and main dimensions.

Graphics memory (technical specifications)

Video memory comparison NVIDIA GeForce GT 645M vs AMD Radeon R6 (Carrizo) 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 GT 645M 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.

Port and Display Support

Port and display support for NVIDIA GeForce GT 645M and AMD Radeon R6 (Carrizo) may be different. When comparing models, it is important to determine what type of monitor and other external devices connection is provided, this is important for connecting not only multiple monitors, but also other accessories. 
For example, DisplayPort and HDMI differ drastically in the quality of the digital signal transmission, plus if you are looking to buy a new graphics card from these two models, it is important to consider which connector is available on your monitor, as you may need to buy a new cable or adapter DisplayPort > HDMI or vice versa.
When comparing NVIDIA GeForce GT 645M and AMD Radeon R6 (Carrizo), choose the graphics card with the more modern HDMI port.

Technologies

Let us compare video cards NVIDIA GeForce GT 645M and AMD Radeon R6 (Carrizo) according to the technologies their manufacturers have implemented. For your reference, not all video card models have these specifications, so a comparison of video card technologies may not occur if one of the two models being compared lacks this specification.
In a comparison between NVIDIA GeForce GT 645M and AMD Radeon R6 (Carrizo) it is possible to give advantage to the model which has at least some technological advantages. It does not affect the overall performance in any way, so we can consider the presence of technology as a simple bonus.

API support

A basic comparison of GPUs NVIDIA GeForce GT 645M and AMD Radeon R6 (Carrizo) for different API versions. 
An API (Application Programming Interface) is a programming interface for interacting with various software.
This information will be useful if you:
1) Looking for a video card to develop applications or programs.
2) Looking for the best graphics card for a developer (universal solution).
3) Want to find the best graphics card for computer or mobile game development.
4) Looking for a graphics card for coding.
No matter what you are looking for you need a graphics card for, you should choose the one that is right for your price and you will find basic API support for developing applications and programs in any of them.

Mining hashrates

Let's compare mining video cards NVIDIA GeForce GT 645M and AMD Radeon R6 (Carrizo). Before exploring the evaluation of cryptocurrency mining, you should know that not all models are suitable for such use. Video cards with less than 8 gigabytes of memory will simply not recoup their cost. 
The complexity of mining is increasing every year, so if you are looking for a video card for a fast payback - you need to pay attention to the top models, which are on the first lines of video cards rating. 
It is very important to understand that video cards in cryptocurrency mining mode work uninterruptedly, almost to the wear and tear of their hardware resource. That is why even the most expensive models often break down.
