BOXX’s APEXX Matterhorn system is based on Intel’s Xeon W-3300 CPU architecture, and C621A chipset, and it represents the pinnacle of Intel’s single socket system performance, with up to 38 CPU cores, 8 channels of DDR4 memory, and 64 lanes of PCIe 4.0 connectivity. The system I am reviewing came configured with the top end Xeon W-3375 CPU, sporting 38 cores, listed as running between 2.5 and 4.0 GHz, with 57MB of cache (1.5MB/Core).

It also has 4 M.2 slots, one of which came populated with a 1TB SSD. The system also shipped to me with an NVidia A6000 card in it, which is the top pro-visualization card in their formerly Quadro lineup.
