1. TOPC’s new AMD mini PC features an MCIO interface, offering doubled bandwidth (128Gbps) for eGPU connections compared to traditional OCuLink ports.
2. The mini PC is equipped with the AMD Ryzen 7 H 255 processor and Radeon 780M iGPU, capable of handling 1080p gaming with adjusted settings.
3. The system includes up to 24GB LPDDR5 RAM, two M.2 slots, and supports WiFi 6E and Bluetooth 5.3, with options for different RAM configurations at competitive prices.
4. The MCIO port’s full potential is limited by the CPU’s PCIe 4.0 support; an upgraded model with PCIe 5.0 compatible CPU is anticipated.
Introduction of TOPC’s AMD-powered Mini PC with MCIO Interface
TOPC has recently announced their latest mini PC that runs on AMD’s processor in China. The cool thing about this system is that it features an MCIO interface, a new technology designed for connecting eGPUs. Though GPD has announced something similar called the Box, which uses PCIe 5.0 x8, it still hasn’t been released to market yet. The MCIO connection stands out as it serves as a more effective replacement to the usual OCuLink port usually seen on mini PCs and handheld gadgets, which usually relies on PCIe 4.0 x4 connections that can handle 64Gbps bandwidth.
Comparison of Bandwidth and Performance
The MCIO PCIe 4.0 x8 interface that the TOPC mini PC adopts is capable of delivering 128Gbps bandwidth, doubling the usual bandwidth of traditional OCuLink connections. This increase should notably reduce performance loss when paired with compatible eGPU, making gaming and graphics-intensive activities more smoother. Users who need better external GPU performance might find this feature quite appealing, especially for high-quality video editing or 3D rendering tasks.
Details about the Mini PC’s Hardware
The mini desktop dubbed TOPC TA255 is powered by the AMD Ryzen 7 H 255 CPU, a refreshed processor from AMD’s Hawk Point series. It also incorporates the Radeon 780M integrated GPU, which can comfortably run many games at 1080p resolution with lower visual settings. The system offers up to 24GB of LPDDR5 RAM and has two M.2 slots that support SSDs for storage expansion. However, TOPC pointed out that this particular CPU doesn’t support PCIe 5.0, limiting the full potential of the MCIO port. There are rumors about newer versions possibly featuring upgraded CPUs that can fully exploit MCIO 5.0 capabilities.
Connectivity Options and Pricing in China
- Wireless connection includes WiFi 6E and Bluetooth 5.3, ensuring modern and fast connectivity.
- In Chinese markets, the mini PC is offered with 16GB of RAM at package price of CNY 2,699 (~$395), and a 24GB version for CNY 2,999 (~$438).
- These prices do not include storage, and it isn’t clear if TOPC plans to release this model globally or keep it confined to China for now.
The detailed specifications and future plans for this AMD mini PC show that it aims to balance compactness with powerful connectivity options, though some limitations due to CPU choice are evident. Whether or not it will reach a broader market remains to be seen, but it certainly poses interesting opportunities for mini-PC enthusiasts and tech lovers alike.
