Unlike Zen 3, Zen 4 offers AVX512 support along with other improvements such as larger caches/registers/buffers across the board.
- GAMING PC - The Radeon 780M (12 CUs / 768 shaders, up to 2,600 MHz) can drive multiple displays simultaneously with a resolution of up to 8K. Hardware encoding and hardware decoding of the most common video codecs (AV1, AVC, HEVC) is also no problem; playing the latest games on FSR settings without issues.
- 64GB DDR5 RAM + 1TB SSD - The K12 mini computer is equipped with Dual 32GB (Total 64GB) SO-DIMM DDR5 5600MHz memory sticks. 1TB PCIe 4.0 SSD and 3x M.2 2280 expansion slots, each supporting up to 8TB (24TB max).

- OCULINK PORT - The Oculink port on the rear interface enables higher bandwidth capabilities, better frame rates and lower lag. The standard also operates at PCIe x4 speeds, compared to Thunderbolt's x3. Gamers and content creators can benefit from Oculink's higher bandwidth, resulting in better performance and lower lag for eGPU setups
- FAST 2.5GBE + WIFI 6E + BT 5.2 - Ethernet 2.5GbE LAN port design provides more applications, such as firewall, multichannel aggregation, soft routing, file storage server. Built-in WIFI 6E / Bluetooth 5.2 is more stable and efficient to connect multiple wireless devices such as projector, printer, monitor, speakers and etc.
- TRIPLE COOLING FANS WITH LIGHTING - Dual turbo CPU fans + a massive DDR5/SSD cooling fan deliver silent, ultra-efficient cooling (just 35dB in Quiet Mode!), while the 3 advanced heatpipes and 360° airflow keep your Ultra 9 285H Mini PC frosty under heavy loads.
