Both support triple 4K displays, which is rare for compact desktops. This means you can run a wide workspace easily.
The connectivity ports are similar, but the E3B has a slight edge in future-proofing.
If you just need to see the hardware side by side, this table is the fastest way to check.
Which has the stronger processor for your work
The processor is the main reason to choose one over the other.
The E3B’s 7530U has 6 cores and 12 threads. This is a significant jump in raw power. Before you buy anything, it is worth looking at desktop versus mini pc.
The P2’s 7330U has 4 cores and 8 threads. It is still a solid Zen 3 chip.
However, for video editing or compiling code, the E3B is much faster.
The extra cores help when you run many browser tabs and apps at once.
If you only run Excel and Chrome, the P2 is more than enough.
But for heavy multitasking, the E3B is the stronger choice.
Think of the P2 as a reliable office worker. Think of the E3B as a power user’s tool.
If your workload includes virtual machines or light 3D work, the E3B’s cores will keep up.
For simple document writing and web browsing, both will feel snappy and responsive.
Gaming performance and graphics limits
Both use integrated graphics, so neither replaces a dedicated GPU.
The E3B’s Vega 7 can run esports titles like Valorant or Fortnite.
The P2’s Vega 6 struggles with the same games at high settings.
For casual gaming, the E3B is the only one that works well.
If you just want to stream 4K video, both are fine.
The E3B wins this category if you plan to play modern games.
The difference in compute units makes a real difference in frame rates.
The E3B has more graphics power, which keeps games smoother.
Do not expect to play AAA titles on either machine at high settings.
They are both mini PCs, so the cooling limits are a factor here.
If you are a gamer, the E3B is the clear winner in this section.
For a home theater box, the P2’s graphics are plenty for video playback. Loaders in this spot often ask about small form factor pc as well.
Storage and RAM expandability options
Both come with 16GB of LPDDR4X RAM.
This memory is soldered, so you cannot add more later.
The E3B has two M.2 slots for storage expansion.
This lets you add a second drive or a larger SSD.
Check the P2’s manual to see if it has the same dual slot layout.
If you need to grow your storage without a new machine, the E3B is the safer bet.
The 16GB RAM limit is a fixed spec for both models.
This means you cannot upgrade to 32GB later on either unit.
Buy the amount of RAM you think you need at the start.
For most users, 16GB is enough for daily tasks and light gaming.
The E3B’s dual M.2 slots are a major advantage for storage.
You can add a fast NVMe drive for games and a cheaper SATA drive for files.
Check the KAMRUI spec sheet to confirm the exact SSD type for the P2.
Pro tip: Do not try to upgrade the soldered RAM. It is not possible. Focus on the storage slots instead.
The E3B includes the dual M.2 slots you need to expand storage easily.
