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.
  • 32GB DDR5 RAM + 2TB SSD - The K12 mini computer is equipped with Dual 16GB (Total 32GB) SO-DIMM DDR5 5600MHz memory sticks. 2TB PCIe 4.0 SSD and 3x M.2 2280 expansion slots, each supporting up to 8TB (24TB max).
