RYZEN 7 H 255 CPU – The Ryzen 7 H 255 is a chip from the Hawk Point family and is an upgraded version of the older Ryzen 7 8745H and has 8 cores (16 threads thanks to SMT support) that run at up to 4.9 GHz, together with the powerful Radeon 780M iGPU. 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).
