KAMRUI E3B (Ryzen Embedded V2748) — Fair Price, Fair Performance?

KAMRUI E3B (Ryzen Embedded V2748) — Fair Price, Fair Performance?

Carbon fiber texture and chrome KAMRUI logo

TL;DR: The KAMRUI E3B with the Ryzen Embedded V2748 is an 8-core/16-thread budget mini PC suitable for daily work, streaming, indie gaming, even tried running a local LLM on it. The fan is basically silent, the build feels way nicer than the price suggests, but the SATA SSD is begging to be replaced. Worth the money if you know what you're getting.

This MiniPC was provided by AceMagic/KAMRUI for review, with NO editorial constraints, all my opinions are my own.

Build Quality & First Impressions

The E3B looks and feels better than it should at this price. The top lid has a diagonal carbon fiber texture with a chrome logo that gives it a more premium vibe than the typical budget mini PC. The chassis is plastic, but it's solid.

This device has a plenty of USB ports with total of 6x USB A, I wish it had an extra USB-C, and 2.5GbE instead of gigabit, but I can't complain at this price point.

The box comes with VESA mount and all necessary screws to mount it to the back of your monitor, as well as a HDMI cable and 65W Power brick.

Two SODIMM slots (one populated with Puskill 16GB), Netac SATA SSD, second M.2 slot marked \"PCIE+SATA\"

Front panel: power button, audio jack, 2x USB-A 3.2 Gen2, USB-C

Rear panel: 4x USB-A, Gigabit LAN, DisplayPort, HDMI, DC-in, exhaust vents

Rubber feet hiding screws

one small annoyance, is the rubber feet to access the screws underneath, they are fixed with some adhesive, and it doesn't re-stick perfectly.

What Can It Actually Do?

This is what actually matters, as at this price point you are not getting this to compare it to the more powerful Ryzen 7 8845HS.

Daily Driver - Browsing, Office, Media Consumption and Multitasking

Windows 11 Pro (24H2) comes pre-installed with zero bloatware found, I also run a full Malwarebytes deep scan out of the box before windows was updated later to 25H2.

Deep scan: 401,992 items, zero threats

When running this with multiple chrome tabs 12+ (YouTube, Gmail, Reddit, Google Docs), it handled everything well with no issues.

The 8 cores 16 threads give it a good multitasking headroom, switching between apps was responsive with no issues.

The only thing that held back the performance is the SATA SSD, while app launches are not slow, but they are not the NVMe fast. More on that below.

Video Streaming — YouTube 2K and 4K

I tested YouTube playback using the stats-for-nerds overlay:

  • 1440p 60fps (VP9): 12 dropped frames out of 1,974 total. Essentially perfect.
  • 4K 60fps (VP9): 96 dropped frames out of 5,481 total. Watchable with occasional micro-stutters but not flawless.

For Netflix, Disney+, and general streaming at 1080p or 1440p, this machine has zero issues. 4K YouTube is the only exception, where the Vega 7 iGPU starts working hard. For a living room media PC, this is more than capable.

Gaming?!

I tested Hollow Knight: Silksong and it ran at a locked 60 FPS with the CPU barely breaking a sweat (10% usage, 65°C). GPU was at 75% utilization, 60°C. Perfectly smooth, no drops.

Hollow Knight: Silksong at 60 FPS, CPU 10%, GPU 75%, 65°C

I see this is the right category of games for this machine, Indie titles/2D games/older 3d titles.

Benchmarks

A single-core score of 1,462 and multi-core of 5,083 is solid numbers for a budget embedded chip

Benchmark Score
Geekbench 6 Single-Core 1,462
Geekbench 6 Multi-Core 5,083
Geekbench 6 GPU (Vulkan) 7,638
CrystalDiskMark Seq Read 554 MB/s
CrystalDiskMark Seq Write 483 MB/s
CrystalDiskMark 4K Random Read 25.6 MB/s
CrystalDiskMark 4K Random Write 112.9 MB/s

The storage numbers confirm this is a SATA SSD, not NVMe. Sequential speeds around 550/483 are typical SATA. The 25.6 MB/s random 4K read is the number that actually affects how snappy things feel, but an NVMe swap would wake it up. The good news: there's a second M.2 slot inside that accepts both NVMe and SATA, so you can add faster storage.

Thermals and Power

During the stress tests, I ran HWinfo64

Thermals and power under sustained load

I noticed that this machine is noticeably silent under the load, while you may slightly hear fan ramping up for seconds before stabilizing back to silent.

while thermals peak to mid 80s it is within the specs of this embedded APU, clocks were steady around 3.9 GHz.

One thing worth mentioning here is that this machine BIOS is locked, there is no option to adjust the TDP (which is fixed to 30W) or control shared memory allocation to the Vega iGPU.

Local LLMs, I tried it so you don't have to

yes, I know, I was just curios to see how it will perform with a shared single channel 16 GB DDR4 3200 Mhz.

so I fired up LM studio and loaded the new Gemma4 E3B, and I got 6 tokens/sec, well, it technically loaded the model, but surely this is not meant for local LLMs.

Gemma4 E2B - 6 Tok/Sec

Conclusion:

The KAMRUI E3B with the Ryzen Embedded V2748 sits in an interesting spot in the budget mini PC market. The 8 cores, silent operation, triple display support, and solid build quality make it a good daily use machine.

The weak points are the SATA SSD is slow for 2026, the RAM ships single-channel, the BIOS is locked down with no TDP or iGPU memory adjustments, and opening the chassis is little annoying. But these are mostly upgradeable problems, not fundamental flaws.

For someone who needs a compact, quiet desktop that handles real multitasking, plays indie games, streams media reliably, and doesn't cost a fortune the E3B will be a good choice for its price.
