UM870 Slim vs UM790 Pro Specs
Processor performance
The MINISFORUM Slim Ryzen 7 Mini PC uses the AMD Ryzen 7 8745H. It has eight cores and sixteen threads with a boost clock up to 4.9GHz. The MINISFORUM Venus Ryzen 9 Mini PC features the AMD Ryzen 9 7940HS. This processor also has eight cores and sixteen threads but reaches a higher boost speed of 5.2GHz. The Venus model offers a slightly higher maximum frequency. This gives it a small edge in raw processing speed for demanding tasks. Both chips support the same thread count for parallel workloads.
Memory expansion limits
Both mini PCs come with 32GB of DDR5 RAM installed. However, their maximum upgrade paths differ. The MINISFORUM Slim Ryzen 7 Mini PC supports expansion up to 96GB of RAM. The MINISFORUM Venus Ryzen 9 Mini PC supports a maximum of 64GB. If you plan to add more memory later for heavy multitasking or virtualization, the Slim model offers greater headroom. The Venus model is limited to two 32GB modules. This makes the Slim unit the better choice for future-proofing memory capacity.
Display connectivity
The MINISFORUM Slim Ryzen 7 Mini PC provides three distinct video outputs. It includes one HDMI 2.1 port, one USB4 port, and one DisplayPort 1.4. This allows you to connect three independent displays simultaneously. The MINISFORUM Venus Ryzen 9 Mini PC offers two HDMI 2.1 ports and two USB4 ports. It supports four screens total. However, the Slim model includes a dedicated DisplayPort, which is useful for specific monitors. The Venus model relies on HDMI and USB4 for all connections. Both support high-resolution outputs for productivity.
USB port variety
The MINISFORUM Slim Ryzen 7 Mini PC includes two USB 3.2 Gen2 Type-A ports and two USB 2.0 ports. This gives you four standard USB-A connections alongside the high-speed USB4 port. The MINISFORUM Venus Ryzen 9 Mini PC features four USB 3.2 Gen2 Type-A ports. It lacks the slower USB 2.0 ports. The Venus model provides more high-speed USB-A ports for peripherals like mice or drives. This is advantageous if you connect many devices that do not require USB4 speeds. The Slim model offers a mix of speeds.
Cooling system
The MINISFORUM Venus Ryzen 9 Mini PC highlights its Cold Wave 2.0 cooling system. It uses liquid metal cooling and includes active coolers for both the memory and the SSD. This setup aims to maintain performance with lower noise levels. The MINISFORUM Slim Ryzen 7 Mini PC data does not specify a liquid metal cooling solution or dedicated active component coolers. It mentions a performance mode TPD up to 65W but lacks detailed thermal management specs. The Venus model appears to have a more advanced thermal design for sustained loads.
Choose the right Mini PC for you
Users needing triple external displays
The UM870 Slim supports three independent displays via HDMI 2.1, USB4, and DisplayPort 1.4. This setup allows you to run 8K@60Hz and 4K@120Hz screens simultaneously. The Venus model only supports four screens if you use its two HDMI ports and two USB4 ports, but the Slim offers more diverse output types for mixed resolution needs.
Users prioritizing maximum CPU speed
The UM790 Pro uses the Ryzen 9 7940HS, which boosts up to 5.2 GHz. This is higher than the Slim’s Ryzen 7 8745H, which tops out at 4.9 GHz. Both have eight cores, but the higher clock speed on the Venus model provides better performance for single-threaded tasks and heavy computing workloads.
Users wanting more storage flexibility
The UM870 Slim includes two M.2 2280 slots, allowing you to install up to two 2TB SSDs for a total of 4TB. The Venus model also has two slots but lists 1TB storage capacity in its key specs. The Slim’s explicit support for dual slot expansion offers greater potential for local data storage.
Users wanting advanced cooling features
The Venus UM790 Pro features a liquid metal cooling system with active memory and SSD coolers. This Cold Wave 2.0 design aims to lower noise levels while maintaining performance. The Slim does not mention this specific cooling technology in its data, making the Venus the better choice for sustained thermal management.
