Rmatamini P99S Mini PC Gets 16GB RAM Upgrade Without Price Increase
A budget mini PC from Newegg now ships with 16GB of RAM instead of 8GB, but the upgrade comes with a trade-off: DDR4 has been replaced by older DDR3 memory.
A rare price stability in a volatile market
According to TechRadar, the Rmatamini P99S mini PC is still available at Newegg for $229, nine months after the outlet first covered it. In a year when memory prices have climbed sharply — a situation the publication refers to as "RAM-mageddon" — the device has received a memory upgrade at no additional cost.
The system now ships with 16GB of RAM, up from 8GB in the earlier version. However, the upgrade includes a notable substitution: the memory type has shifted from DDR4 to DDR3. The operating system has also been updated from Windows 10 Pro to Windows 11 Pro.
Hardware specifications and performance
The mini PC measures 201 x 201 x 147 mm and includes a GeForce GTS450 GPU with 2GB of dedicated memory. Combined with the system RAM, total available memory reaches 18GB.
At its core is a 16-core, 32-thread Intel Xeon server CPU. TechRadar reports the processor achieves a Passmark score of 18,847, placing it ahead of the AMD Ryzen Z1 in multi-threaded performance. The publication notes the CPU outperforms others in this price bracket, though it runs hot and loud under load.
The package also includes a 256GB SSD, a 450W power supply, and 13 ports and connectors, excluding two antennas.
The trade-offs to consider
TechRadar's review is candid about the compromises. The GTS 450 is an older GPU. Power consumption is described as "outrageous." Beyond the DDR3 downgrade, the system uses dated components that may not suit all users.
The publication frames the central question directly: whether a buyer can accept these drawbacks in exchange for the performance and memory capacity at this price point.
How it compares to alternatives
TechRadar identifies two competing mini PCs in the sub-$300 range.
The Bosgame E5 Plus is listed at $219 on Amazon for Prime members, a 27% discount. It features an AMD Ryzen 3 5400U CPU, two 2.5Gb LAN ports, support for three 4K monitors, and an AMD integrated GPU. Compared to the Xeon in the Rmatamini, it offers faster single-thread performance but lower multi-thread performance. It ships with 8GB of shared memory.
The Chuwi LarkBox X costs $294.49. It uses an Intel Core i3-1220p CPU, which TechRadar says nearly doubles the single-thread score of the Xeon but still trails in multi-threaded workloads. It has half the memory of the upgraded Rmatamini but is described as a more modern, compact, and power-efficient option with up-to-date connectivity.
What this means for buyers
TechRadar's assessment suggests the P99S occupies a specific niche: users who prioritize raw multi-threaded performance and memory capacity over efficiency, modern connectivity, and acoustic comfort. The upgrade from 8GB to 16GB of RAM is meaningful for multitasking and memory-intensive applications, but the shift to DDR3 memory may partially offset those gains in real-world performance.
For users whose workloads benefit from high core counts — such as virtualization, encoding, or certain professional applications — the P99S may remain compelling at $229. For those who value quiet operation, lower power draw, or newer platform features, the Bosgame E5 Plus or Chuwi LarkBox X may be more appropriate despite their limitations.
TechRadar notes its overall opinion of the device has changed little since the initial review, maintaining that it has no direct rivals at this price point.
