It's great to hear that DEPED has upgraded their desktop units. Based on your predictions, it seems that these new units will have a significant performance boost compared to their previous laptops. The AMD Ryzen 5 processor with Radeon Vega integrated graphics is a great combination, providing both processing power and decent graphics capabilities.
As for the RAM, you mentioned that it could be around 8 to 16GB. This would be a good amount for general use and some light gaming. However, if the desktops are intended for more demanding applications, such as video editing or 3D modeling, then 16GB or more would be preferable.
It's also great to hear that the new desktop units will be equipped with an SSD. This will provide faster boot times and application load times compared to the previous slow HDDs.
As for the dedicated GPU, it would be a welcome addition for those who want to use the desktops for gaming or more demanding graphics work. However, it's important to note that DEPED's main focus might not be on gaming or graphics-intensive work. Therefore, it's possible that they may not include dedicated GPUs in their desktop units.
Overall, the new DEPED desktop units seem like a significant improvement over their previous laptops. It will be interesting to see the final specifications and performance of the new desktops once they are released.
