Inside the ultra-minimalist glossy black housing of the soundproofed Nanoxia Deep Silence 4 system case we find a powerful 3.5GHz Intel Core i7-4770K processor, which adds Hyper Threading and a slight speed bump over the 3.4GHz Core i5. Unfortunately, for those craving ultimate speed, this CPU is running at its stock speed and is therefore running slower than any of the overclocked Core i5 chips. Overclocking requires considerably more power and more cooling, so Quiet PC has focused on keeping the system running as quietly as possible rather than reaching for the upper limits of speed.

Quiet PC Serenity Mini Gamer: benchmarks

PCMark 7 returned a score of 5098 points, which is hardly to be sniffed at, but when you consider that this is a more expensive processor delivering much lower performance than an overclocked Core i5, you’ll need to share Quiet PC’s preference for peace and quiet over performance if this is to be the gaming PC for you. Gaming performance of the Serenity Mini Gamer also lags significantly behind the competition. Crucially, our high-quality 1080p-resolution tests all fell far below 60 fps, so keen gamers will need to reduce quality settings to obtain smooth game play. Even the 720p-mode test of Alien vs Predator failed to reach 60 fps. The PC is fitted with a Gigabyte GTX 650 Ti OC Windforce graphics card, but its factory overclocking can’t make up for this considerably less powerful GPU.
